Fabrication of carbon black nanoparticles from green algae and sugarcane bagasse

There are several industrial uses for carbon black (CB), an extremely fine powdered form of elemental carbon that is made up of coalesced particle aggregates and almost spherical colloidal particles. Most carbon black is produced from petroleum-derived feedstock, so there is a need to find an alternative method to produce CB, which relies on renewable resources such as algae and agricultural waste. A process involving hydrolysis, carbonization, and pyrolysis of green algae and sugarcane bagasse was developed, as the optimal hydrolysis conditions (16N sulfuric acid, 70 °C, 1 h, 1:30 g/ml GA or SC to sulfuric acid ratio), a hydrolysis ratio of 62% for SC and 85% for GA were achieved. The acidic solution was carbonized using a water bath, and the solid carbon was then further pyrolyzed at 900 °C. The obtained carbon black has a high carbon content of about 90% which is confirmed by EDX, XRD, and XPS analysis. By comparison carbon black from sugar cane bagasse (CBB) and carbon black from green algae Ulva lactuca (CBG) with commercial carbon black (CCB) it showed the same morphology which was confirmed by SEM analysis. The BET data, showed the high specific surface area of prepared CB, which was 605 (m2/g) for CBB and 424 (m2/g) for CBG compared with commercial carbon black (CBB) was 50 (m2/g), also the mean pore diameter of CBB, CBG and CCB indicated that CBB and CBG were rich in micropores, but CCB was rich in mesoporous according to IUPAC classification. This study might have created a technique that can be used to make carbon black from different kinds of biomass.

Effect of Temperature and Amount of Nickel Catalyst on Yield and Bio-Oil Composition in Pyrolysis of Sugarcane Bagasse

The abundance of bagasse waste from sugar cane processing needs special attention apart from being used for direct combustion in boilers. Sugarcane bagasse waste can be further processed by pyrolysis so that it will produce bio-oil, bio-gas and char products which have the potential to be used as fuel or high-value chemicals. Pyrolysis of bagasse was carried out to study the effect of temperature and the ratio of the amount of Ni catalyst on the yield and composition of bio-oil in the form of oxygen to carbon (O/C) ratio, hydrogen to carbon (H/C) ratio, higher heating value (HHV), content of oxygenated compounds and range of aromatic compounds. Pyrolysis of bagasse is carried out in a fixed bed reactor with a heating rate of 10-12 ºC/minute to the desired temperature. Pyrolysis with and without a catalyst was carried out at a temperature range of 300-600 ºC with a variation of Ni catalyst weighing 2.5 grams and 5 grams. Liquid product analysis was tested using GCMS (Gas Chromatography and Mass Spectroscopy) to determine the compound content in the liquid product resulting from pyrolysis of sugarcane bagasse. Bio-oil resulting from pyrolysis of sugarcane bagasse contains several dominant compounds including alcohol, fatty acids, esters, carotenoids and levoglucosan. However, the yield of sugarcane bagasse bio-oil without catalyst was dominated by high levoglucosan, namely 70.52%. Meanwhile, the bio oil resulting from pyrolysis which varied with 2.5 grams and 5 grams of Ni catalyst was dominated by esters, namely 69.07% and 81.68% respectively. These compounds have different chemical properties and applications, and understanding the composition of bio-oil can help in deciding how to use it efficiently.

Green hydroxyapatite-zeolite catalyst derived from steel waste as an effective catalyst for the hydrocarbon production via co-catalytic pyrolysis of sugarcane bagasse and high-density polyethylene

Hydroxyapatite-zeolite (HAP-ZE) catalyst prepared from steel waste was utilised in co-catalytic pyrolysis of sugarcane bagasse (SB) and high-density polyethylene (HDPE) for bio-oil production. The highest bio-oil yield (71.19 wt%) was obtained at HAP-ZE to SB/HDPE ratio of 1:6, and mass ratio of SB to HDPE of 40:60. HAP-ZE favoured the production of hydrocarbon and alcohol and inhibited the production of acid. The acid sites promoted the hydrogenation and deoxygenation via hydrocarbon pool while the basic sites promoted the deoxygenation reactions via decarboxylation and decarbonylation. HAP-ZE large pores facilitates access of bulky pyrolyzates to active sites, promoting deoxygenation and hydrocarbons formation.

Perspectives on the use of biochar in the valorization of mining wastes from sulfide minerals flotation: Recovery of metals and effects on toxicity

This study aims to evaluate the use of two biochars obtained by pyrolysis of sugarcane-bagasse and compare it with commercial activated carbons as catalysts for the recovery of metals from one mining waste from sulfide minerals flotation (MW). It is also intended to determine the influence of carbon materials on the toxicity of the final residues. Leaching tests were performed in 250 mL erlenmeyer flasks using plates with magnetic stirrers during 24 h, at 90 °C and a stirring speed of 350 rpm. For each test, 5 g of MW were mixed with carbon material in two ratios of MW/carbon material (1/0.1 and 1/0.2 wt/wt) and 100 mL of leaching agent (H2SO4 solution at pH = 0.8–0.9 and 5 gL−1 of Fe3+). The experimental results showed that the addition of biochar and activated carbon enhances the recovery of Cu and Zn. The use of commercial activated carbons in ratios of 1/0.1 and 1/0.2 MW/carbon material leads to the extraction of more than 91 % of Cu and 97 % of Zn, after 24 h of leaching. For biochars, the highest recovery values of Cu (82.9 %) and Zn (98.1 %) were achieved with biochar prepared at 750 °C and used in the ratio of 1/0.2. However, the addition of carbon materials does not improve the recovery of Co. The presence of carbon materials decreased the electrical conductivity and pH of the final residue. The leaching of samples MW + W35 (1/0.1) and MW + BC550 (1/0.1) leads to a germination index higher than 90 %. For two biochars, all samples showed non-phytotoxicity.

Multi-Distributed Activation Energy Model for Pyrolysis of Sugarcane Bagasse: Modelling Strategy and Thermodynamic Characterization

The multi-distributed activation energy model (multi-DAEM) is the most effective approach for outlining the kinetics model of biomass pyrolysis. The purpose of this study is to identify the optimal number and shape of the DAEM for sugarcane bagasse pyrolysis and to discuss its thermodynamic characteristics using the combination of multi-DAEM and differential thermal analysis (DTA). The heating rate of 10, 30, and 50 °C/min was employed. The results revealed that the multi-DAEM with five pseudo components and Weibull distribution shape gave the lowest relative root mean of the squared error (RRMSE) of 0.66% and 0.41%, respectively. Kinetic and thermodynamic studies showed that the 1st and 4th pseudo components which represent lignin, have activation energy (E0) of 189.6 and 180.6 kJ/mol, and less endothermic or possibly exothermic properties. Meanwhile, the 2nd, 3rd, and 5th pseudo components which represent cellulose, hemicellulose, and moisture have activation energy (E0) of 176.1, 152.2, and 145.6 kJ/mol, respectively, and endothermic properties.

Application of response surface methodology for the modelling and optimisation of bio-oil yield via intermediate pyrolysis process of sugarcane bagasse

ABSTRACT The search for renewable resources has grown globally as a result of the harmful effects of fossil fuel use on the environment, such as global warming and acid rain. Biomass fuels do not contribute to the accumulation of carbon dioxide in the atmosphere. This study utilised response surface methodology for the optimisation of pyrolysis process parameters (temperature, heating rate, reaction time, nitrogen flow rate, and particle size) at five levels of experimental runs to enhance bio-oil production from the intermediate pyrolysis of sugarcane bagasse. The bio-oil yield increased continuously with an increase in T (320–520°C) and H (7.5–12.5°C/min) due to complete pyrolysis, while a decrease in bio-oil was noticed at a T (520–720°C) and H (22.5–27.5°C/min) due to secondary cracking such as thermal cracking, repolymerisation and recondensation that might enhance the yield of NCG and biochar. The optimum bio-oil yield (46.7 wt%) was achieved at a temperature, reaction time, heating rate, nitrogen flow rate, and particle size of 493.7°C, 15.5 min, 24.5°C/min, 225 cm3/min, and 0.1 mm, respectively. Results showed that the predicted data closely correlated with the experimental data (p < 0.05, R2 = 0.9891). Hence, the model is suitable and can accurately predict the experimental data. The presence of alkene, alcohol, and ester makes the bio-oil applicable for energy generation to power heavy equipment, ships, compressor, and boilers. Likewise, the presence of by-products such as oleic acids, methyl ester, 9,17-octadecdienal, and 9,12-octadecadienoyl chloride makes it suitable as fuel for high-speed diesel engines, powering heavy machines, vehicle locomotion, marine equipment, mining types of machinery, and manufacturing industries.

Biochar: An environmentally friendly platform for construction of a SARS-CoV-2 electrochemical immunosensor

Waste management is a key feature to ensure sustainable consumption and production patterns, and to combat the impacts of climate change. In this scenario, the production of biochar from different biomasses results in environmental and economic advantages. In this study, biochar was produced from sugarcane bagasse pyrolysis, to immobilize biomolecules, in order to assemble an electrochemical immunosensor to detect antibodies against SARS-CoV-2. For this, screen-printed carbon electrodes (SPCE) were modified with a dispersion of biochar and used to immobilize the receptor-binding-domain (RBD) against virus S-protein, through EDC/NHS crosslinking reaction. Under the best set of experimental conditions, negative and positive serum samples responses distinguished based on a cutoff value of 82.3 %, at a 95 % confidence level. The immunosensor showed selective behavior to antibodies against yellow fever and its performance was stable up to 7 days of storage. Therefore, biochar yielded from sugarcane bagasse is an ecofriendly material that can be used as a platform to immobilize biomolecules for construction of electrochemical biosensors.

Magnetic biochar for removal of perfluorooctane sulphonate (PFOS): Interfacial interaction and adsorption mechanism

Perfluorooctane sulphonate (PFOS) as a long chain of persistent, bio-accumulative, and toxic emerging organic contaminant needs to be removed from contaminated water and soils. The development of cost-effective adsorbents is critical for remediation of PFOS. In this study, magnetic biochar (MBC) was synthesised by pre-modification of mineral-rich sugarcane bagasse (SB) with hematite nanoparticles (Fe 2 O 3 , ∼ 100 nm) for the adsorption of PFOS. Characterisation of MBC indicated the introduction of magnetic property and metals-based functional groups due to the incorporation of iron (hematite) nanoparticles. The oxygen-containing functional groups were retained by pyrolysis of sugarcane bagasse at low temperatures, which introduced hydrophilic properties of the MBC. The metal-based and hydrophilic functional groups could act as active sites for PFOS removal. Sorption isotherm results suggested maximum adsorption capacity of the MBC as 120 . 44 ± 12 . 37 mg/g for PFOS. Adsorption followed pseudo-second-order (PSO) kinetic model and Langmuir and Freundlich isotherm models, demonstrating monolayer and/or multilayer formation (depending on the solution concentration) of PFOS on the adsorbents through the physisorption and chemisorption of PFOS. The adsorption of PFOS decreased with increasing solution pH due to increase of electrostatic repulsion among negatively charged functional groups and anionic PFOS headgroup. Energy-dispersive X-ray spectroscopy (EDS) elemental mapping confirmed that PFOS (F) has strong co-distribution with oxygen, calcium, aluminium, potassium, and silicon, but limited co-distribution with carbon, indicating that electrostatic interaction and ion exchanges play a vital role in chemisorption. • Magnetic biochars (MBC) were synthesised from agricultural waste and iron nanoparticles. • The maximum adsorption capacity of MBC was 120.44 mg/g for PFOS. • PFOS–PFOS interaction, electrostatic interaction, and pore filling play critical role in PFOS adsorption. • Isotherm and kinetic model fitting demonstrated physisorption and chemisorption of PFOS.

Activated Carbon from Sugarcane Bagasse Pyrolysis for Heavy Metals Adsorption

Sugarcane bagasse is an agro-industrial waste available in enormous quantities in Egypt. It is rich of organic carbon which makes it a potential feedstock for activated carbon production. This study provides an optimized pyrolysis method for activated carbon production from Sugarcane bagasse. Sugarcane bagasse samples impregnated with sulfuric acid, for 24 h, and carbonized at 500 °C, for two hours, yielded the best activated carbon with a surface area of 431.375 m2/g. The best impregnation ratio was 2.5:1 (sulfuric acid/bagasse). The prepared activated carbon was used for adsorbing heavy metals (Pb, Cd, Mn, Cu, Cr) from Nile Tilapia reused frying oil. It could adsorb 80% of the heavy metals and particularly removed the Cd. The characteristics of the prepared activated carbon are comparable to those recommended for the commercial activated carbon. The production cost of the activated carbon using this method is about 707 $ which is cheaper than the commercial activated carbon by about 40%.

Valorization of Eucalyptus, Giant Reed Arundo, Fiber Sorghum, and Sugarcane Bagasse via Fast Pyrolysis and Subsequent Bio-Oil Gasification.

Fast pyrolysis of giant reed Arundo (Arundo donax), fiber sorghum (Sorghum bicolor L.Moench), eucalyptus (Eucalyptus spp.), and sugarcane bagasse (Saccharum officinarum) was studied in bench-scale bubbling fluidized bed reactor. Product yields were determined, and detailed physicochemical characterization for produced fast pyrolysis bio-oils (FPBOs) was carried out. The highest organic liquid yield (dry basis) was observed with sugarcane bagasse (59–62 wt %), followed by eucalyptus (49–53 wt %), giant reed Arundo (39 wt %), and fiber sorghum (34–42 wt %). After the pyrolysis experiments, produced FPBOs were gasified in an oxygen-blown autothermal catalytic reforming system for the produced synthesis gas. The gasifier consists of a partial oxidation zone where the FPBO is gasified, and the raw syngas is then reformed over a fixed bed steam-reforming catalyst in the reforming zone. The gas production (∼1.7 Nm3/kg FPBO) and composition (H2 ∼ 50 vol %, CO 20–25 vol %, and CO2 25–30 vol %) were similar for all FPBOs tested. These results show that the combination of fast pyrolysis with subsequent gasification provides a technically feasible and feedstock flexible solution for the production of synthesis gas.

Switching the production of oxygenated platform chemicals during pyrolysis of sugarcane bagasse by regulating the secondary reactions

The secondary reactions during biomass pyrolysis inhibit the selective conversion of biomass into value-added oxygenated platform chemicals. Herein, regulating the secondary reactions during pyrolysis of sugarcane bagasse was systemically explored by adjusting the pyrolysis temperature and H2SO4 loading. It is found that reducing the pyrolysis temperature of sugarcane bagasse from 500 to 300 °C suppresses both primary and secondary reactions. Further adjusting H2SO4 loading can promote primary depolymerization reactions and secondary dehydration reactions during pyrolysis of sugarcane bagasse at 300 °C. When H2SO4 loading is less than 0.5 %, the depolymerization of hemicellulose to form xylosan dominates. The highest yield of xylosan (30.3 %) is obtained by the pyrolysis of 0.5 % H2SO4-loaded sugarcane bagasse at 300 °C. When H2SO4 loading further increases from 0.5 to 1.0 %, the depolymerization of cellulose to levoglucosan becomes the major reaction. The highest yield of levoglucosan (34.2 %) is produced by pyrolysis of 1.0 % H2SO4-loaded sugarcane bagasse at 300 °C. When H2SO4 loading is greater than 1.0 %, the secondary dehydration reactions of cellulose and hemicellulose to respective levoglucosenone and furfural are dominant. These findings demonstrate that adjusting H2SO4 loading is capable of regulating primary and secondary reactions during biomass pyrolysis at low temperatures, thus enabling product switching.

Thermal Conversion of Sugarcane Bagasse Coupled with Vapor Phase Hydrotreatment over Nickel-Based Catalysts: A Comprehensive Characterization of Upgraded Products

In the present work, we compared the chemical profile of the organic compounds produced in non-catalytic pyrolysis of sugarcane bagasse at 500 °C with those obtained by the in-line catalytic upgrading of the vapor phase at 350 °C. The influence over the chemical profile was evaluated by testing two Ni-based catalysts employing an inert atmosphere (N2) and a reactive atmosphere (H2) under atmospheric pressure with yields of the liquid phase varying from 55 to 62%. Major changes in the chemical profile were evidenced in the process under the H2 atmosphere, wherein a higher degree of deoxygenation was identified due to the effect of synergistic action between the catalyst and H2. The organic fraction of the liquid phase, called bio-oil, showed an increase in the relative content of alcohols and phenolic compounds in the GC/MS fingerprint after the upgrading process, corroborating with the action of the catalytic process upon the compounds derived from sugar and carboxylic acids. Thus, the thermal conversion of sugarcane bagasse, in a process under an H2 atmosphere and the presence of Ni-based catalysts, promoted higher deoxygenation performance of the pyrolytic vapors, acting mainly through sugar dehydration reactions. Therefore, the adoption of this process can potentialize the use of this waste biomass to produce a bio-oil with higher content of phenolic species, which have a wide range of applications in the energy and industrial sectors.

Modelling of Liquid-Liquid Equilibria Using NRTL and UNIFAC Equations in the Extraction of Bio-Oil-Based Phenolics Produced from the Pyrolysis of Sugarcane Bagasse

An exploration on renewable energy resources has been paid more attention due to the depletion of the fossil-based energy resource. In addition, their safe and environmentally friendly properties have attracted experts’ interest. One of the renewable energy resources is the bio-oil produced from sugarcane bagasse. The bio-oil was produced through a pyrolysis at 500°C. However, the produced bio-oil showed a high content of phenolics, c.a. 40-60%. A liquid-liquid extraction to remove the phenolics using methanol-chloroform solvents would be beneficial to improve the stability of the bio-oil as well as to obtain high purity phenolics. Modelling of the liquid-liquid equilibria in the extraction was then developed using NRTL and UNIFAC equations. The empirical quantitative data of phase equilibrium system were calculated on both the extract and raffinate phases. The lowest RMSD value of 0.043160 was obtained from the calculations using NRTL equation at an extraction temperature of 50°C. Thus, the most suitable model was achieved using NRTL equation.

Green synthesis of carbon nanomaterials from sugarcane bagasse using bio-silica supported bimetallic nickel-based catalysts

Sugarcane bagasse (SCB) can be considered as an inexpensive and abundant source for the production of valuable carbon nanomaterials (CNMs). Herein, the synthesis of CNMs via sugarcane bagasse (SCB) pyrolysis was investigated using a simple two-stage process. Bio-silica extracted from rice husk (RH-SiO2) was loaded with 50%Ni, 40%Ni-10%Cu, 40%Ni-10%Mo, and 40%Ni-10%Co and evaluated as catalysts for the production of CNMs from pyrolysis products. The fresh catalysts were characterized by XRD, H2-TPR, and CO2-TPD analyses, while the spent catalysts were characterized using TEM and Raman spectroscopy. The XRD and TPR results of the fresh catalysts demonstrated the existence of non-interacted NiO species in the monometallic Ni/RH-SiO2 catalyst. However, mixed oxides of NixCu1-xO, NiMoO4, and NiCo2O4 species were presented in Ni-Cu, Ni-Mo, and Ni-Co catalysts, respectively, in addition to non-interacted NiO species. TEM images revealed the presence of both carbon nanotubes (CNTs) and graphene nanosheets (GNSs) depending on the catalyst type. The results showed that the presence of mixed oxide species in the catalyst was associated with CNTs formation, while the existence of agglomerated Ni particles was correlated to GNSs formation. The catalytic activity of the catalysts in terms of carbon yield was arranged as follows: 50%Ni > 40%Ni-10%Co > 40%Ni-10%Cu > 40%Ni-10%Mo. Raman spectra proved the production of high-quality CNMs using all Ni-based catalysts.

Evaluation of influential factors in microwave assisted pyrolysis of sugarcane bagasse for biochar production

Microwave assisted pyrolysis (MAP) is an efficient technology for the production of biochar. However, its large-scale application is limited due to lack of process optimization resulting in lower yield. Identification of significantly influencing parameters is essential for efficient optimization. Thus, in present study, screening of factors like the feedstock amount, feedstock size, moisture content, catalyst dosage, microwave power and exposure time using half fractional factorial screening design was done to identify the most influencing factor affecting sugarcane bagasse biochar yield. The formulated linear model was found to be significant with a regression coefficient ( R 2 ) of 0.9365. Half normal plot and the Pareto chart analysis showed that MAP to be mostly influenced by feedstock amount, microwave irradiation time, feedstock size and microwave power. Maximum biochar yield of 44.46% was obtained with 10 g feedstock (0.015 cm) at 720 W after 20 min, which would be optimized further to improvise the process efficiency. • Microwave power and time shows prominent impact on biochar yield. • Appropriate moisture content facilitates better microwave assisted pyrolysis. • Maximum biochar yield of 44.46% was obtained under optimal conditions. • Microwave biochar shows good porous characteristics and fixed carbon.

Catalytic pyrolysis of sugarcane bagasse by zeolite catalyst for the production of multi-walled carbon nanotubes

Recently, the disposal of waste by beneficial and environmentally friendly methods has attracted great attention. In this work, we have studied the production of high-value carbon nanotubes (CNTs) which have remarkable applications by catalytic pyrolysis of sugarcane bagasse (SCB) as an agricultural waste using a two-stage process. Various reaction factors including the effects of zeolite types (HZSM-5, HMOR, and HY), pyrolysis temperatures (450−700°C), and SCB/ZSM-5 ratios (3−12) on SCB pyrolysis were investigated to generate CNTs from pyrolysis products. A Co-Mo/MgO catalyst was used for growing CNTs via the decomposition of pyrolysis products. The morphological structure and quality of CNTs were characterized using TEM and Raman spectroscopy, while the fresh Co-Mo/MgO catalyst was characterized by XRD and TPR analyses. The results showed that zeolite type, pyrolysis temperature, and SCB/ZSM-5 ratio had significant effects on the CNTs yield. The optimum carbon yield (24.9%) was achieved using the HZSM-5 catalyst at the pyrolysis temperature of 500°C and with the SCB/ZSM-5 ratio of 6. TEM observations confirmed the growth of bamboo-like carbon nanotubes (BCNTs) and carbon nano-onions (CNOs) in different proportions according to the reaction parameters. Also, CNTs with the largest diameter distribution range (7−76 nm) were produced using the SCB/ZSM-5 ratio of 6. Raman spectra demonstrated the production of high-quality CNTs under all studied conditions.

An investigation into the pyrolysis and oxidation of bio-oil from sugarcane bagasse: Kinetics and evolved gases using TGA-FTIR

Bio-oil produced from the pyrolysis of sugarcane bagasse has the potential to be used as a sustainable and renewable energy source. In the present study, a non-isothermal thermo-gravimetric analysis (TGA) of the pyrolysis (in N2 atmosphere) and combustion (in the air) of bio-oil from sugarcane bagasse was investigated at three heating rates: 5, 10, and 20 °C/min. The sample was heated from room temperature up to 900 °C and the evolved gases in the TG furnace were carried to a Fourier transform infrared (FTIR) cell where the composition of the gases and the functional groups present there were analyzed. A global kinetic analysis was performed to obtain the Arrhenius kinetic parameters for the pyrolysis and oxidation of the bio-oil using the distributed activation energy model. Three distinct stages, namely; low-temperature oxidation (LTO), fuel decomposition (FD), and high-temperature oxidation (HTO) were observed during the oxidation of bio-oil. The initial devolatilization of the oxygenated compounds observed during pyrolysis was similar to the LTO stage observed during combustion. The intensity of the CO2 FTIR peaks seen during the bio-oil combustion was 10 times the intensity of the CO2 peaks attained during pyrolysis. The TGA-FTIR analysis of the sugarcane bagasse bio-oil sheds new light on its thermal degradation/oxidation characteristics.

Optimization of Pyrolysis Temperature and Particle Size on the Phenols and Hemicellulose Fast Pyrolysis Products in a Tandem Micro-Pyrolyzer

Fast pyrolysis of sugarcane bagasse was investigated in a tandem micro-pyrolyzer. The effects of temperature and particle size on the phenolic compounds and hemicellulose products distribution were examined during fast pyrolysis process. For this, changes in the micro-reactor parameters were made (particle size between 0.1 and 0.5 mm and reactor temperature between 450 and 600 °C). Response Surface Methodology (RSM) was used to optimize pyrolysis parameters. The results indicated that the temperature had the highest effect on phenolic and furfural-type compounds, whereas the particle size did not exhibit significant effects on carboxylic acid products. The largest number of phenolic compounds were achieved upon decreasing the temperature and increasing particle size. The ANOVA analysis revealed that the full quadratic model was more adequate for phenolic and furfural compounds, whereas the linear square model was accurate for carboxylic acids. In general, a tandem micro-pyrolyzer interfacing with a GC-MS analysis facilitated a better understanding of a chemical composition of biomass and therefore, could remarkably improve the valorising of sugarcane bagasse application in biorefinery processes.
