High-Silica Layer-like Zeolites Y from Seeding-Free Synthesis and Their Catalytic Performance in Low-Density Polyethylene Cracking.

Layer-like FAU-type zeolite Y was synthesized by an organosilane-assisted low-temperature hydrothermal method and its catalytic activity was verified in the low-density polyethylene (LDPE) cracking process. The synthesis procedure of high-silica layer-like zeolite Y was based on organosilane as a growth modifier, and for the first time, the seeding step was successfully avoided. The X-ray diffraction and electron microscopy studies, scanning electron microscopy and transmission electron microscopy confirmed the formation of pure FAU structure and zeolite particles of plate-like morphology arranged in the manner of the skeleton of a cuboctahedron. The in situ Fourier transform infrared (FT-IR) spectroscopic studies, low-temperature nitrogen sorption, and electron microscopy results provided detailed information on the obtained layer-like zeolite Y. The acidic and textural properties of layer-like zeolites Y were faced with the catalytic activity and selectivity in the cracking of LDPE. The quantitative assessment of catalyst selectivity performed in FT-IR/GC–MS operando studies pointed out that LDPE cracking over the layer-like material yielded value-added C3–C4 gases and C5–C6 liquid fraction at the expense of C7+ fraction. The detailed analysis of coke residue on the catalyst was also performed by means of FT-IR spectroscopy, thermogravimetric analysis, and thermoprogrammed oxidation coupled with mass spectrometry for the detection of oxidation products. The acidic and textural properties gave a foundation for the catalytic performance and coking of catalysts.

Oxidation of benzene to phenol with N2O over a hierarchical Fe/ZSM-5 catalyst

Catalytic oxidation of benzene with N2O to phenol over the hierarchical and microporous Fe/ZSM-5-based catalysts in a continuous fixed-bed reactor was investigated. The spent catalyst was in-situ regenerated by an oxidative treatment using N2O and in total 10 reaction-regeneration cycles were performed. A 100% N2O conversion, 93.3% phenol selectivity, and high initial phenol formation rate of 16.49 ± 0.06 mmolphenol gcatalyst−1 h−1 at time on stream (TOS) of 5 min, and a good phenol productivity of 147.06 mmolphenol gcatalyst−1 during catalyst life-time of 1800 min were obtained on a fresh hierarchical Fe/ZSM-5-Hi2.8 catalyst. With the reaction-regeneration cycle, N2O conversion is fully recovered within TOS of 3 h, moreover, the phenol productivity was decreased ca. 2.2 ± 0.8% after each cycle, leading to a total phenol productivity of ca. 0.44 tonphenol kgcatalyst−1 estimated for 300 cycles. Catalyst characterizations imply that the coke is rapidly deposited on catalyst surface in the initial TOS of 3 h (0.28 mgc gcatalyst−1 min−1) and gradually becomes graphitic during the TOS of 30 h with a slow formation rate of 0.06 mgc gcatalyst−1 min−1. Among others (e.g., the decrease of textural property and acidity), the nearly complete coverage of the active Fe-O-Al sites by coke accounts for the main catalyst deactivation. Besides these reversible deactivation characteristics related to coking, the irreversible catalyst deactivation is also observed with the reaction-regeneration cycle. The latter is reflected by a further decreased amount of the active Fe-O-Al sites, which agglomerate on catalyst surface with the cycle, likely associated with the hard coke residue that is not completely removed by the regeneration.

Mathematical simulation of furnace processes during fired pulverized coal

The article presents the study of combustion and heat transfer processes in large-scale objects are extremely difficult both analytically and experimentally. The combustion of non-design coals in boiler units is often accompanied by a decrease in the completeness of fuel burnup, undesirable redistribution of heat flows and other negative factors due to different thermal characteristics of the fuel. The possibility of effective burnout of polyfractional non-design solid fuel in the combustion chamber of a boiler unit with solid ash removal is considered on the basis of a numerical study of jointly occurring aerothermochemical processes. The problem of numerical modeling of the staged burnout of coal particles is solved, starting from the evaporation of the moisture contained in them to the burning out of their coke residue when moving in the carrier phase. Numerical studies of physical and chemical processes in the combustion chamber were carried out for three loads (50%, 70%, 100%) based on the developed FIRE 3D calculation complex. The Euler-Lagrange model for a dusty flow is applied, the closure of the averaged Navier-Stokes equations is performed by the k-ε turbulence model, the second order of accuracy is used in numerical calculations. The main results of three-dimensional modeling are presented in the form of velocity and temperature fields, the distribution of O2 and CO concentrations along the height of the furnace volume. The results of mathematical modeling showed good agreement with the available analytical values. Based on the data obtained, it can be stated that it is possible to organize the combustion of non-design fuel in the boiler unit under consideration. It has been established that when operating at loads below the nominal, a redistribution of burner jets is observed, which negatively affects the reliability and efficiency of the boiler. To increase the efficiency of the boiler unit at reduced loads, a wider study of options for redistributing the proportions of the fuel-air mixture and secondary air is necessary.

Spectral Characteristics of the Glow of Coal Flames during the Exposure to Laser Pulses

The results of measuring the characteristics of the glow of coal flames at the initial moments of ignition under the action of laser pulses of a neodymium laser (1064 nm, 120 μs) are presented. In microparticles of coal grades DG, G, Zh, and K, when the corresponding critical energy densities are exceeded during a laser pulse, the surface ignites and flame propagates at a speed of V~50 m/s. The emission spectra of flames are contributed by the emission of emitted hot coal particles, excited H2* and H2O* molecules, as well as the flame emission arising from the oxidation of carbon (CO*) and carbon monoxide (CO2*) by atmospheric oxygen. Keywords: coal, laser, ignition, flame, volatile substances, degree of coalification, coke residue.

Highly electrochemically and thermally stable donor–π–acceptor triphenylamine-based hole-transporting homopolymersviaoxidative polymerization

Polymers combining high electrochemical and thermal stability, good solubility, highTgand high coke residue with low-lying HOMO levels and reasonable hole mobilities in thin films are reported in this study.

Improving the environmental friendliness of a solid fuel boiler house using SHF energy

To reduce harmful emissions, solid fuel consumption and increase the efficiency of the boiler plant, an automated system with a combined heating device and a condensing air heater connected in series was designed. In a combined heating device (SHF + flue gases) equipped with a magnetron, quality control and additional preparation of solid fuel with a high moisture content (up to 80%) for combustion are carried out. In the condensing air heater, the heat of the flue gases coming into it from the combined heating deviceand the latent heat of vaporization are extracted. The use of this system allows reducing the moisture content and temperature of flue gases, the volume of harmful emissions from the boiler plant in the form of nitrogen oxides and dioxides (NOx), carbon oxides (CO), ash, volatile coke residues. By increasing the volume and reducing the corrosiveness of the condensate formed from the flue gases in the condensation air heater during the drying process of fuel with a high moisture content, it can be subsequently used as process and make-up water. Practical application of the system makes it possible to reduce the cost of generating heat energy by the boiler house by increasing the use of low-calorie fuel with a high moisture content in the form of waste from logging, wood processing, low-grade coal and peat, which also has a positive environmental effect.

Study of the phase transition ability of coal tar pitch and their coke products under the influence of temperature used to synthesise carbon composite materials

Using differential scanning calorimetry and thermogravimetric analysis showed the marking temperature of coal tar pitch is 107.8°C. The thermal decomposition of the pitch is divided into three main stages, corresponding to three phases α, β, γ, with a coke yield of 47% at 800°C. The change in the XRD diagram showed a clear transition from the amorphous state of carbon to the highly ordered crystalline structure of graphite after treatment at 2,200 and 2,700°С. The purity of the pitch sample and the structure of the CCC carbon-carbon composite material after heat treatment at 2,700°C were studied using scanning electron microscopy and energy-dispersive X-ray spectroscopy methods. The results showed that after heat treatment, the C content in the sample reached more than 99.5%, and the coke residues after graphitization were bound and connected to the carbon fabric into a mass of graphite material.

Thermogravimetric Analysis of the Combustion of Khakassia Coal, Pine Sawdust and their Blends

A thermogravimetric analysis (TGA) of the combustion of two long-flame hard coals from the Republic of Khakassia, pine sawdust and their blends in the air stream, depending on the chemical composition and thermal characteristics of the samples, was carried out. The ignition temperature and the burn-out temperature of the coke residue of the studied samples were determined by extrapolation using the TG and DTG curves. The indices of ignition, burnout and combustion are calculated taking into account the time parameters. The ignition temperature of pine sawdust was Ti = 308 °C, the burnout temperature was Tb = 490 °C. When sawdust was added to the coals, the combustion process of the blend shifted to lower temperatures, and the ignition temperature decreased by more than 100 °C compared to the ignition temperature of the coals. The energy -efficient compositions of blends that ensure their high combustion characteristics are determined

Kinetics of steam regeneration of SAPO-34 zeolite catalyst in methanol-to-olefins (MTO) process

• With the increase of regeneration temperature, the compositions of residual coke on the catalyst change from pyrene and phenanthrene to naphthalene; • The appearance of nitrogen oxide compounds during steam regeneration makes the regeneration temperature not too high. • We derive the kinetics of steam regeneration and obtain an activation energy of about 177.8 kJ/mol during the steam regeneration process. • Compared with the air combustion process, the steam regeneration process is more difficult to occur. Methanol-to-olefins (MTO) is industrially applied to produce ethylene and propylene using methanol converted from coal, synthetic gas, and biomass. SAPO-34 zeolites, as the most efficient catalyst in MTO process, are subject to the rapid deactivation due to coke deposition. Recent work shows that steam regeneration can provide advantages such as low carbon dioxide emission and enhanced light olefins yield in MTO process, compared to that by air regeneration. A kinetic study on the steam regeneration of spent SAPO-34 catalyst has been carried out in this work. In doing so, we first investigated the effect of temperature on the regeneration performance by monitoring the crystal structure, acidity, residual coke properties and other structural parameters. The results show that with the increase of regeneration temperature, the compositions of residual coke on the catalyst change from pyrene and phenanthrene to naphthalene, which are normally considered as active hydrocarbon pool species in MTO reaction. However, when the regeneration temperature is too high, nitrogen oxides can be found in the residual coke. Meanwhile, as the regeneration temperature increases, the quantity of residual coke reduces and the acidity, BET surface area and pore structure of the regenerated samples can be better recovered, resulting in prolonging catalyst lifetime. We have further derived the kinetics of steam regeneration, and obtained an activation energy of about 177.8 kJ·mol −1 . Compared that with air regeneration, the activation energy of steam regeneration is higher, indicating that the steam regeneration process is more difficult to occur.

The influence of ash-content pulverized coal particles on their burning characteristics in tuyere hearth

Effect of ash content in coal dust on the burning characteristics in tuyere zone of blast furnace is studied. The ash is considered as an individual fraction in addition to two fractions of coal dust. It is shown, that the variation of pulverized coal fractional composition allows increase of carbon monoxide yield and fuel particles burnout. The presence of ash results in oxygen zone extension and increase of coke residue burnout. At the same time the total coal dust burnout is lower than that of low-ash coal. Fine pulverized coal combustion is characterized by increased production of carbon monoxide and reduction of carbon dioxide percentage.

Direct non-thermal plasma regeneration of deactivated HZSM-5 for catalytic pyrolysis of rape straw

A direct non-thermal plasma (DNTP) method was proposed to remove coke after catalytic pyrolysis of rape straw at atmospheric pressure and room temperature. Through the optical emission spectroscopy (OES) analysis, it was found that the active substances O3 and O were generated inside the deactivated catalyst and reacted violently with the coke. After DNTP regeneration under different voltages of 20 kV, 22 kV, 24 kV, and 26 kV, the residual coke of each regenerated catalyst was almost completely removed, which were 2.65 %, 1.99 %, 1.29 %, and 0.30 %. Compared with fresh catalyst, the specific surface area of Cat-22 increased the most (34.09 %), and the total acid content increased by 24.11 %. The bio-oil obtained by Cat-22 had the highest monocyclic aromatic hydrocarbons content (46.93 %), which was 29.65 % higher than that of fresh catalyst. After fifteen cycles of catalysis-regeneration at 20 kV, it was found that the content of hydrocarbons of the bio-oil sample could be retained at 94.5 % of that in the original catalytic test. Through the DNTP technology based on the theoretical basis to realize the recycling of the catalyst, it will promote the development of biomass field in a more sustainable and cleaner way.

АСПЕКТИ РОЗРОБЛЕННЯ ВОГНЕЗАХИСНИХ КОМПОЗИЦІЙ ДЛЯ КОНСТРУКЦІЙ З ТЕКСТИЛЬНИХ ЗАЙМИСТИХ ВИРОБІВ

The results of experimental studies on the effectiveness of fire protection of easily erected structures made of flammable textile products are presented. An analysis of the directions of use of easily erected structures made of flammable textile products indicates a steady trend towards an increase in their use during the temporary fulfillment of certain tasks of the Armed Forces of Ukraine and units of the. During the heating of such structures, ignition and rapid spread of fire are possible. The operating statistics for easily erected structures have found a low level of safety due to the use of natural fibers (e.g., linen, cotton and blends), which are highly sensitive to heat and fire. Reduction of combustibility and the development of non-combustible and non-combustible materials is one of the main directions for preventing fires and solving the problem of expanding the scope of these materials. Treatment with fire protection means significantly affects the spread of the flame, allows you to reduce the smoke-generating ability and heat release significantly. After the test, it can be seen that the sample of the textile material sustains spontaneous combustion for more than 5 s; sample damage is more than 150 mm. After the test, it is clear that the sample of textile material does not support self-combustion for no more than 5 s; sample damage is no more than 100 mm. The inhibition of the process of ignition and flame propagation for such a sample is associated with the decomposition of fire retardants under the influence of temperature with the absorption of heat and the release of incombustible gases (nitrogen, carbon dioxide), a change in the direction of decomposition towards the formation of incombustible gases and a hardly combustible coke residue. This leads to an increase in the thickness of the coke layer and inhibition of the heat transfer of the high-temperature flame to the material, which indicates the possibility of the transition of textile materials during processing with a fire retardant composition to materials that are non-combustible, which do not spread the flame by the surface.

Catalytic effects of Al2O3 nano-particles on thermal cracking of heavy oil during in-situ combustion process

In-situ combustion (ISC) is regarded as one of the most promising and economic alternative in the development of heavy oil reservoir. Maintaining high temperature oxidation (HTO) reaction with a high cracking efficiency at relatively low fuel consumption is deemed particularly crucial for the success of ISC process. In this work, Al2O3 nano-particles as a catalyst for achieving this during ISC is investigated in three parts. First, kinetic cell experiments with ramped temperature oxidation (RTO) process were conducted on the heaviest fraction of crude oil (residue) to obtain the apparent activation energy (Ea) fingerprints for oil-oxygen reactions with and without Al2O3. Second, thermogravimetric analysis-mass spectrometry-differential scanning calorimetry (TGA-MS-DSC) was used to detect pyrolysis products from the residue and characterize its dynamic change during the process, with SEM and EDS employed to observe the morphology and verify the condition of nano-particles afterwards. Third, combustion tube experiments were performed on the whole crude to analyze the distinction between combustion behavior with and without Al2O3. The results showed addition of Al2O3 catalyst resulted in: Ea decreased and oscillated visibly, temperature of fire front increased by 60.3–83.6 °C, speed of propagation was enhanced by 37.3%, residual coke remains in the quartz sand at the end of combustion tube experiment decreased by 24.8%, production efficiency increased by 13–64% with the reduction of COx production (12.3%) and oxygen consumption (26.9%). This shows a higher ultimate oil recovery is possible with higher upgraded oil percentage during a catalyst-assisted ISC process, which bodes well for future field application.

The influence of heating on the carbon isotope composition, organic geochemistry and petrology of coal from the Upper Silesian Coal Basin (Poland): An experimental and field study

The impact of natural intra-deposit heating on the δ13C signature, organic geochemistry, and petrology of coal and coal-bearing rocks characterised by various degrees of coalification and palaeoenvironments in the Upper Silesian Coal Basin, Poland, is elaborated. Reconstruction of palaeofire performed by heating experiments up to 400 °C in open and semi-closed systems with different heating regimes confirms the crucial significance of temperature and oxygen access. In open-system heating, released 13C-depleted gases enrich residue coke in 13C compared to raw coal. Petrological examinations did not show the impact of palaeofires on the maceral properties of coal. However, the carried-out experiment caused the formation of devolatilisation pores, rounded edges, cracks, pale rims, as well as higher reflectance and paler colour that was what was expected. Extractable compounds become highly depleted, and low-weight organic compounds nearly absent. Relatively high contents of combustion-formed PAHs are an indicator of open-system heating. In semi-closed systems, the final total isotopic composition was almost unchanged as no components are carried away though changes in petrography and geochemistry occur. Increased extract yields reflect the release of bitumen from closed pores and partial pyrolysis of organic matter. Depletion of lighter n-alkane compounds, total carbon TC and volatiles decrease, and variable values of various alkyl aromatic hydrocarbon ratios are also indicative of semi-closed heating. Coal seams suspected of intra-deposit heating show geochemical and isotopic features similar to semi-closed- rather than open-system heating, and their δ13C signatures and organic geochemistry did not respond strongly during laboratory re-heating.

Physicochemical Phenomena of CO2 Injection in Polymetallic Ironmaking

Abandoned basic oxygen furnace gas (ABOFG) is a kind of byproduct fuel resource produced in the basic oxygen furnace (BOF) steelmaking process with a high temperature of 1773–1873 K and 20–40% (vol.%) CO and 20–30% (vol.%) CO2 and is usually ignited and discharged as waste gas (34.7% abandoned rate). The effects and physicochemical phenomena of injecting CO2‐containing ABOFG into high‐Cr‐bearing vanadia−titania magnetite ironmaking are investigated. The thermodynamic calculation shows that the ABOFG injection changes the gas partial pressure and the oxygen potential in the slag−coke interfaces and suppresses the titanium carbonitride formation. According to the results of softening−melting−dripping experiments, the content of titanium carbonitride in the high‐titanium slag decreases from 2.53% to 1.14% as the CO2 content in ABOFG increases from 0 to 30%, which is conducive to improving the high‐temperature physicochemical properties of molten slag. The recoveries of vanadium and chromium are also improved with the decrease in iron loss. Moreover, the residual coke still maintains a considerable compressive strength with a slight effect from ABOFG injection, which is expected to reduce carbon consumption.

Boudouard reaction accompanied by graphitization of wrinkled carbon layers in coke gasification: A theoretical insight into the classical understanding

The carbon dioxide gasification mechanism of coke was investigated by combining a particulate coke reaction experiment and theoretical calculations. Characterization results obtained via X-ray diffraction and X-ray photoelectron spectroscopy showed that the increase of graphitic carbon proportion, that is, a graphitization process, led to a decrease in the strength of the coke residue. Molecular dynamics simulations based on a reactive force field corresponded closely to the experimental characterization results. From this, the main formation path of carbon monoxide was identified to be accompanied by the reconstruction of carbon matrix. It is confirmed that defects on the carbon layer acted as key intermediates in the layer reconstruction and flattening. The energy and potential barrier of the obtained elementary reactions were determined by means of density functional theory. The highest potential barrier of the carbon layer oxidation by carbon dioxide molecules indicated that it was the rate-controlling step of the coke gasification process. Moreover, compared with the other carbon atoms, those with large wrinkle degree were likely to react with carbon dioxide to form a flat carbon layer. This work explains why different coke samples have significantly different activation energies for the carbon dioxide gasification reaction. Furthermore, the essential relationship between the coke strength and the gasification reaction is established, thereby providing theoretical support for improved utilization of coke in a blast furnace.

Efficient utilization of coal slime using anaerobic fermentation technology

In order to increase the utilization of coal slime, realize efficient utilization of resources and protect the environment, the feasibility of anaerobic fermentation technology employing coal slime was explored. The biodegradation of coal slimes and its influence on the utilization characteristics were analyzed using biogas production simulations, drying dehydration and thermogravimetric (TG) analysis. The results showed that the organic matter in various coal slimes could be converted to biomethane. In addition, the main methanogenic pathway was the reduction of CO2. Moreover, lower the metamorphic degree of coal slimes and higher the ash content, more conducive were they to the dehydration of coal slimes. After biodegradation, the temperatures of four coal slimes during the stages of release of moisture, volatile combustion, residual coke combustion and burnout advanced to varying degrees. Moreover, the combustion performance improved. The research results provided a novel idea for the efficient utilization of coal slime.

Utilization of waste tire powder for gaseous fuel generation via CO2 gasification using waste heat in converter vaporization cooling flue

This study proposes a novel approach to effectively solve the problems associated with reusing waste tires by injecting waste tire powder into the converter vaporization cooling flue (CVCF) to obtain gaseous fuels via CO2 gasification using high-temperature waste heat. The gasification behavior was investigated in a CO2 atmosphere using a thermogravimetry (TG)-mass spectrometry (MS) (TG-MS) system. A settling furnace was used to simulate CVCF to investigate the effects of gasification temperatures. The activation energy (E) was calculated using the Flynn-Wall-Ozaw (FWO) and Kissinger-Akahira- Sunose (KAS) methods. The main components in the gas phase were typically CO, CH4, H2, H2O, and C2H6 in a temperature range of 300°C–500 °C. The average activation energy of waste tire decomposition was 144.51 kJ/mol. The increase in temperature and decrease in particle size increased the amount of combustible gas and LHV value. The increase in the CO2/CO ratio decreased the content of residual coke from 12.62% to 11.98%. The lower heating values were determined to range between 8.75 and 10.27 MJ/Nm3. The research preliminarily confirmed the feasibility of injecting waste tire powders into the CVCF to generate gaseous fuels using waste heat via CO2 gasification.

A study of the polymerization of a monofunctional benzoxazine monomer based on phenol and aniline and its copolymerization with epoxy resins

In the work, the liquid monofunctional benzoxazine monomer based on phenol and aniline (P-a) was synthesized in melt and benzoxazine-epoxy compositions based on it were obtained. The processes of polymerization of a benzoxazine monomer and its copolymerization with epoxy resins of various structures and functionality in catalyzed and non-catalyzed systems have been investigated, and the rheological properties of the compositions have been evaluated. For the obtained polybenzoxazines and benzoxazine-epoxy copolymers, the thermal characteristics were determined, in particular, the glass transition temperature, the temperature of the onset of intense destruction and the coke residue. It has been established that the structure and functionality of epoxy resins have a different effect on the thermal characteristics of the copolymers.

Gasification Plants for Chemical Production: The Impact of Carbon Utilization on CO2 Capture from the Facility

Coal and other disadvantaged fuels such as petroleum coke and refinery bottoms can be used for the production of chemicals around the world. Coal is an established feedstock in gasification and has been the primary focus in markets like China, where the use of coal to chemicals is needed due to limited access to oil and natural gas reserves. Disadvantaged feedstocks such as petroleum coke and heavy residues are currently experiencing a shift in market utilization. New legislation on criteria pollutants in countries like India and IMO2020 legislation are reducing the size of petroleum coke and residue feedstock end markets. The need to dispose of these disadvantaged feedstocks has created new project opportunities for gasification plants. However, with the new opportunities come increasing pressures to lower the CO2 but also increasing the opportunity to take advantage of CO2 emission reduction benefits and/or to deploy the CO2 for enhanced oil recovery. Air Products provides high quality technical solutions as a technology supplier, process integrator and operator. This paper will present our unique perspective on the amenable streams for CO2 capture within the gasification plant, thoughts on how the technologies are developing to further reduce the overall CO2 footprint of a coal to syngas facility, and what the major driving forces are present in selecting technologies and process options. Gasification produces CO2 as a natural byproduct of the reactions taking place in the gasifier to produce syngas as well as downstream water gas shift reactions. The high temperatures and pressures that various gasification and shift processes can operate under provide potential capture points in the plant flowsheet depending on the quantity and purity of CO2 needed. In addition, product syngas requirements dictate the purity and CO to H2 ratio of the product syngas which has a direct influence over the amount of CO2 available to capture from the product syngas streams. Pressurized CO2 sources are a more cost effective way to capture high levels of CO2. As compared to SMR technologies in which approximately 50% of the CO2 is at pressure, solid and liquid gasification technologies contain almost all of the CO2 within the pressurized syngas stream. The amenable product stream locations vary in quantity, purity, and pressure of CO2. Therefore, the degree of capture from the plant is an important variable when selecting the location and technology employed to capture at a specific facility. Gasification also has the advantages of heat recovery from the process to produce steam which can offset the steam demand from low pressure CO2 sources like on purpose boilers. Heat recovery and integration options are core to producing an economic solution to the CO2 capture. Various technologies exist for the removal of CO2 from gasification plants. The methanol based Rectisol process is one technology employed in gasification plants for the effective removal of CO2 from the pressurized gasification syngas streams. It is a proven technology for purifying the syngas stream, but it is not the only technology which can be employed to capture CO2. Numerous studies on decarbonized fuels have outlined Rectisol as well as other acid gas removal technologies for power production. In this paper, the focus will be on revisiting these standby technology options and introducing additional technologies, like Air Products Sour PSA technology, that provide options to capture various levels and purities of CO2, for the solid or liquid feedstock to syngas markets. Currently, Air Products has formed a joint venture with the Luan Coal Group to operate a large-scale gasification plant which converts coal to liquids. The carbon in the coal does not leave the facility as CO2 as in decarbonized power production processes. A significant portion of the carbon is incorporated into the final product from the syngas. This utilization of carbon in the products influences the amenable envelope of technologies that can be used to capture CO2 from the plant. Maximizing the carbon that resides in product molecules provides an interesting twist on previous decarbonized power carbon capture studies. Maximizing carbon utilization provides insight into how to design the balance of plant and what technologies could be developed that would directly impact the material balance as well as the CO2 emissions from the overall facility. Air Products is uniquely positioned to analyze the technical challenges of capturing CO2 from gasification facilities. Identifying cost effective solutions to individual opportunities and the technical driving force influencing design choices will be discussed in this paper.
