Hydrogen production from the steam reforming of biogas over Ni-based catalyst: The role of promoters and supports

Biogas steam reforming (BSR) is a sustainable and low-carbon strategy for H2 production. Herein, the conventional Ni/Al2O3 catalyst was modified by distinct promoters (Co, Cu, Fe) and supports (ZrO2, MgO, CeO2) for H2 production from BSR. The effects of modification methods on the catalytic performance were evaluated based on the activity tests and characterizations of catalysts. The introduction of the mono-metal promoter or the mono-metal oxide support was beneficial for the BSR to different degrees. Ni-Co/Al2O3 exhibited higher CH4 conversion ratio (xCH4), and Ni-Fe/Al2O3 showed the least carbon deposition among the catalysts modified by the mono-metal promoter. Both Ni/ZrO2-Al2O3 and Ni/MgO-Al2O3 modified with mono-metal oxide support showed high xCH4 approaching 90 %, with the former leading to less carbon deposition. The coupled modification by metal promoter and metal oxide support did not show a satisfactory performance. The modification by bi-metal oxide support, ZrO2 and MgO, showed the most promising catalytic conversion of CH4 and H2 production among all these modified catalysts, and the maximum values of xCH4 and H2 yield (YH2) reached 90.71 % and 86.06 %, respectively. Ni/MgO-ZrO2-Al2O3 also exhibited excellent stability with a total carbon deposition of 0.042 g·gcata−1 in the 10 h stability test.

Predicting nickel catalyst deactivation in biogas steam and dry reforming for hydrogen production using machine learning

This study employs Random Forests (RF) and Artificial Neural Networks (ANN) to model the transient behavior of Ni catalyst deactivation during steam and dry reforming of model biogas containing H2S, with a focus on hydrogen production. Deactivation, induced by carbon deposition and sulfur poisoning, is a complex and transient phenomenon demanding precise kinetic mechanisms for accurately predicting Ni catalyst behavior in biogas reforming. Black-box machine learning (ML) models are developed, incorporating catalyst properties, biogas composition, and operating conditions. Encompassing both dry and steam reforming, the ML models aim to predict catalyst behavior, expressed in terms of packed bed reactor exit mole fractions (H2, CO, CH4, and CO2) and conversions (CH4 and CO2). The ML models are trained and tested across a temperature range of 700–900 C with 0–145 ppm of H2S in model biogas (CH4/CO2 ratio varying from 1.0 to 2.0). RF outperforms the ANN across all performance metrics, including overall R2 and root mean squared error (RMSE). The RF achieves a mean overall R2 of 0.979, with training and testing RMSE equal to 6.7×10−3 and 1.47×10−2 respectively. In contrast, the ANN achieves a mean overall R2 of 0.939, with training and testing RMSE equal to 2.6×10−2 and 2.55×10−2 respectively. Moreover, pre-trained RF models are validated with unseen data of dry reforming of biogas containing 30 ppm of H2S (25 data points). It is suggested that 35 % of this unseen experimental data is required to train the RF model for it to predict catalyst deactivation, achieving a validation R sufficiently2> 0.9. The mean overall R2 values attained by the RF fine-tuned on 35 % of the unseen experiment data for both CH4 and CO2 conversions, as well as for all mole fraction predictions, are 0.952 and 0.948, respectively.

A green hydrogen production system based on solar-assisted biogas steam reforming

In the context of a carbon–neutral world, biogas reforming technology has potential to realize the production of green hydrogen with distributed production. Traditional green hydrogen production system based on biogas reforming dependent on high temperature condition during the reforming process; besides, biogas is always identified as a free energy resource in existing studies. This study develops a new way for green hydrogen production based on solar-assisted biogas steam reforming. The heat demand in the digester is considered in the newly proposed system; thus, more reasonable conclusion in regard to system thermal performance could be draw compared with existing studies. An advanced biogas reforming process with high steam-to-carbon molar ratio by introducing a parabolic trough solar collector is designed. At the same time, coupled with the carbon capture scheme proposed by previous study, it has great potential to realize hydrogen production with negative carbon emissions. Combined with the carbon deposition analysis, system integrated thermal performances are compared within the margin of safety. High steam-to-carbon molar ratio in the new system obviously improves the hydrogen production rate, with a maximum increase of hydrogen yield reaching 24.21 kg/h. In addition, the heat supply capacity is also significantly enhanced, which can meet the heat load of the digester when the ambient temperature is 4.03 °C (the reference system is only 20.19 °C). In terms of the integrated thermal performance, the hydrogen production efficiency of the new system is 33.60 percentage points higher than that of the reference system. This study provides a new idea for green hydrogen production from the perspectives of low temperature condition and negative carbon emissions.

Parametric and sensitive analysis of Pd-Ag membrane reactor performance in biogas reforming to generate decarbonized hydrogen by Computational Fluid Dynamic-Response Surface Methodology

The efficient production of hydrogen from renewable sources is pivotal for the development of sustainable energy systems. Biogas steam reforming (BSR) conducted in palladium-based membrane reactors (MRs) offers a pathway for high-purity H2 generation at lower temperatures compared to traditional processes. In this study, a computational fluid dynamics (CFD) model was developed to simulate the BSR process within a Pd-Ag MR. The CFD model has integrated comprehensive kinetics, mass transport, and hydrodynamics, and its accuracy was confirmed through validation against experimental data, demonstrating substantial agreement. As a novel approach, to optimize the BSR reaction conditions to get the best MR performance, the CFD model was coupled with response surface methodology (RSM), which has been employed to enable the identification of optimal values for key parameters such as reaction temperature, pressure, gas hour space velocity, feed molar ratio, and sweep gas ratio, where the temperature was found to have the most significant impact on the MR’s performance within the examined intervals of input parameters. The objective of RSM method applied to CFD modeling was to maximize with high accuracy CH4 conversion, H2 recovery, and reduce CO2 emissions. RSM models effectively established correlations between input parameters and responses. The determined optimal conditions for the BSR process were a temperature of 683 K, a reaction pressure of 6 bar, a GHSV of 3000 h−1, a H2O/CH4 ratio of 1.34, and a sweep ratio of 9. Under these conditions, the system achieved remarkable results with 100 % CH4 conversion, 43 % H2 recovery, and an 81 % reduction in CO2 emissions. This study underscores the effectiveness of integrating CFD with RSM for the precise modeling and optimization of MRs in BSR reactions. The synergy between these approaches provides a robust framework for advancing the efficiency and sustainability of hydrogen production processes from renewable sources.

Simulation modelling of hydrogen production from steam reforming of methane and biogas

The use of fossil fuels in energy systems has environmental consequences, which are driving investigations into H2 production. While steam methane reforming is the most well-known method for producing H2, other thermochemical pathways are becoming more prevalent. Steam-reforming of biogas is also a beneficial procedure for producing eco-friendly hydrogen gas and minimizing the burden on fossil fuels. In this study, a simulation modelling of steam methane reforming (SMR) and steam biogas reforming (SBR) are presented. The model reveals the hydrogen production reaction mechanism and validates its performance through simulation analysis using COMSOL Multiphysics 5.6 software (finite element analysis). The developed model has been validated by available previous experiments and simulation work for biogas reforming with various compositions as well as the methane reforming process. The core aim of this study is to estimate the yield of H2 for SMR, and H2 and CO for SBR at steam carbon ratio (S/C) from 1 to 3 with various temperatures, and find the optimum temperature for the reforming process. The yields of hydrogen (mol/mol-CH4) are achieved higher from SMR as 12% and 22 % for comparison with the experiment and previous simulation study at S/C = 2, at a temperature of 700 °C. The H2 yields (mol/mol-CH4) are achieved higher as 30% at 800 °C, 21% at 1000 °C, and 20% at 1200 °C (average percentage of mol for steam carbon ratio from 1 to 3) and compared with previous simulation study at the same operating temperatures, stated by SBR. The findings indicate that the proposed work offers a viable method for utilizing distributed renewable methane resources to fuel cells and generate local electricity.

A Review on the Use of Catalysis for Biogas Steam Reforming

Hydrogen production from natural gas or biogas, at different purity levels, has emerged as an important technology with continuous development and improvement in order to stand for sustainable and clean energy. Regarding biogas, which can be obtained from multiple sources, hydrogen production through the steam reforming of methane is one of the most important methods for its energy use. In that sense, the role of catalysts to make the process more efficient is crucial, normally contributing to a higher hydrogen yield under milder reaction conditions in the final product. The aim of this review is to cover the main points related to these catalysts, as every aspect counts and has an influence on the use of these catalysts during this specific process (from the feedstocks used for biogas production or the biodigestion process to the purification of the hydrogen produced). Thus, a thorough review of hydrogen production through biogas steam reforming was carried out, with a special emphasis on the influence of different variables on its catalytic performance. Also, the most common catalysts used in this process, as well as the main deactivation mechanisms and their possible solutions are included, supported by the most recent studies about these subjects.

Sorption-enhanced biogas steam reforming over the Pb-modified Ni–CaO bifunctional catalysts

Sorption-enhanced biogas steam reforming (SESRB) can efficiently produce high-purity “green hydrogen” from biogas with the adaptability to high and variable CO2 content of biogas. The key challenge faced by SESRB is the rapid, sintering-induced decline of sorption capacity. Herein, a Pb-modified Ni–CaO bifunctional catalyst is prepared based on the adsorption of Pb2+ by CaCO3, in which the replacement of CaCO3 by PbCO3 is achieved on the surface of CaCO3. After thermal treatment, CaPbO3 was generated on the surface of CaO particles in the bifunctional catalyst, by which CaO particles are separated effectively, and thus the sintering of Ca species is weakened. 5Ni–8PbO–CaO as the optimum catalyst with only 7.9 wt% PbO maintains 57.6 % of the initial sorption capacity after 20 cycles, higher than that of 5Ni–CaO (40.5 %). Due to the excellent stability of the 5Ni–8PbO–CaO catalyst, high-purity hydrogen (94.1 vol%) with 95.0 % CH4 conversion is continuously obtained from biogas for 20 consecutive SESRB-decarbonation cycles.

Biogas Steam Reforming in Wastewater Treatment Plants: Opportunities and Challenges

Hydrogen as an energy vector is going to play an important role in the global energy mix. On the other hand, wastewater management has become a worldwide concern, as urban settlements have been considerably increasing for decades. Consequently, biodigestion to produce biogas (rich in methane) in water treatment plants could be an interesting starting point to obtain a valuable gas that can be converted into hydrogen through steam reforming. The aim of this work was to review the main aspects concerning steam reforming of biogas from wastewater treatment plants. For this purpose, the whole chain, from water treatment to hydrogen production and purification, was considered, paying attention to the main challenges and new technologies for its optimization. Thus, a wide range of possibilities is offered, from direct energy use of syngas to high purification of hydrogen (mainly through pressure swing adsorption or membrane reactors), presenting advantages and disadvantages. In any case, the role of catalysts seems to be essential, and aspects such as hydrogen sulfide and coke deposition control should be addressed. In conclusion, biogas steam reforming applied to wastewater treatment plants is a reality, with serious possibilities for its global implementation at the industrial level, according to techno-economic assessment.

Techno-economic modeling of a novel poly-generation system based on biogas for power, hydrogen, freshwater, and ammonia production

In the current study, a new poly-generation energy system run by biogas steam reforming is proposed and assessed. To dissect the techno-economic feasibility of the offered system, energy, exergy, and sum unit cost of the products (SUCP) are considered as robust indicators for the system appraisal. Also, to acquire enhanced thermodynamic efficiencies, the system has benefited from the careful design of the biogas steam reforming unit, modified Rankine cycle, ammonia synthesis unit, hydrogen generation equipment as well as reverse osmosis unit. It is uncovered that the prepared poly-generation system is qualified to provide 687.4 kW of power, 0.9662 kg/s of freshwater, 0.15 kg/s of hydrogen, and 1.149 kg/s of ammonia. Besides, the energy and exergy efficiencies of the system have been calculated at about 18.9% and 16.9%, respectively with a total exergy destruction rate of 51020.78 kW. Also, following the results of the thermodynamic appraisals, the biogas steam reforming reactor and ammonia synthesis reactor have the highest contributions to inefficiencies happening in the system. Furthermore, from a sweeping sensitivity investigation, the optimum performance of the system appears in a biogas steam reforming reaction temperature of 1050K. Also, the SUCP decreases by about 21 $/GJ by increasing the Biogas Steam Reforming reactor pressure.

Process Simulations of High-Purity and Renewable Clean H2 Production by Sorption Enhanced Steam Reforming of Biogas

Renewable clean H2 has a very promising potential for the decarbonization of energy systems. Sorption enhanced steam reforming (SESR) is a novel process that combines the steam reforming reaction and the simultaneous CO2 removal by a solid sorbent, such as CaO, which significantly enhances hydrogen generation, enabling high-purity H2 production. The CO2 sorption reaction (carbonation) is exothermic, but the sorbent regeneration by calcination is highly endothermic, which requires extra energy. Biogas is one of the available carbon-neutral renewable H2 production sources. It can be especially relevant for the energy integration of the SESR process since, due to the exothermic sorption reaction, the CO2 contained in the biogas provides extra heat to the system, which can help to balance the energy requirements of the process. This work studies different process configurations for the energy integration of the SESR process of biogas for high-purity renewable H2 production: (1) SESR with sorbent regeneration using a portion of the produced H2 (SESR+REG_H2), (2) SESR with sorbent regeneration using biogas (SESR+REG_BG), and (3) SESR with sorbent regeneration using biogas and adding a pressure swing adsorption (PSA) unit for hydrogen purification (SESR+REG_BG+PSA). When using biogas as fuel (Cases 2 and 3), these configurations were studied using air and oxy-fuel combustion atmospheres in the sorbent regeneration step, resulting in five case studies. A thermodynamic approach for process modeling can provide the optimal process operating conditions and configurations that maximize the energy efficiency of the process, which are the basis for subsequent optimization of the process at the practical level needed to scale up this technology. For this purpose, process simulations were performed using a steady-state plant model developed in Aspen Plus, incorporating a complex heat exchanger network (HEN) to optimize heat integration. A comprehensive parametric study assessed the effects of biogas composition, temperature, pressure, and steam to methane (S/CH4) ratio on the process performance represented by the selected key performance indicators, i.e., H2 purity, H2 yield, CH4 conversion, cold gas efficiency (CGE), net efficiency (NE), fuel consumption for the sorbent regeneration step, and CO2 capture efficiency. H2 with a purity of 98.5 vol % and a CGE of 75.7% with zero carbon emissions can be achieved. When adding a PSA unit, nearly 100% H2 purity and CO2 capture efficiency were achieved with a CGE of 77.3%. The use of oxy-fuel combustion during regeneration lowered the net efficiency of the process by 2.3% points (since it requires an air separation unit) but allowed the process to achieve negative carbon emissions.

Hydrogen production by the steam reforming of synthetic biogas in atmospheric-pressure microwave (915 MHz) plasma

This paper is a contribution to the development of microwave plasma-based technology aimed at efficient hydrogen (H2) production from a so-called synthetic biogas, considered a mixture of methane (CH4) and carbon dioxide (CO2), which can contain up to 70% CH4. In this work, we tested the performance of a waveguide-supplied metal cylinder-based microwave plasma source (MPS) operating at 915 MHz at atmospheric pressure as a tool for the efficient production of H2 in the steam reforming of the synthetic biogas. The test showed that the steam reforming of the synthetic biogas could be carried out under a wide range of working parameters without soot formation and extinction of the microwave discharge. We found that there is a minimal H2Osteam consumption rate for a given CH4 input volume content, which ensures stable operation of the MPS (no soot). The experiments did not show that increasing the amount of H2Osteam rate above the minimal value for a given CH4 input volume content results in an increase in the H2 production rate, energy yield, CH4 conversion degree, and H2 output concentration. To describe the MPS performance, which also takes into account a factor of the utilization of the CH4 feedstock, we introduced a new parameter, called an energy–CH4 feedstock consumption yield. The best results in terms of the H2 production rate, the energy yield, and the CH4 conversion degree were 239 g[H2]/h 36.8 g[H2]/kWh, and 74.3%, respectively. This shows that the application of the steam reforming, instead of the dry reforming, resulted in a 1.5-fold increase of the H2 production rate and the corresponding energy yield.

Optimization of biogas-reforming conditions considering carbon formation, hydrogen production, and energy efficiencies

Hydrogen production from biogas requires energy efficiency. This study systemically compared pure biogas reforming, CO2-free biogas steam reforming, and biogas steam reforming. A comprehensive evaluation combining thermodynamic analysis, energy efficiency evaluation, and experimental validation was performed to compare the reaction types. Biogas steam reforming is the most attractive reforming reaction because it has the lowest SEC. In addition, the main parameters for the reaction conditions were investigated to optimize hydrogen production from biogas. The optimal conditions for the biogas steam reforming were determined as 750 °C and an H2O/CH4 ratio of 1.5. Finally, the previously developed Ni–MgO–CeZrO2 catalyst was tested under the optimized reaction conditions. Consequently, the catalyst showed high catalytic performance and was maintained for 30 h, even at a high GHSV of 36 000 h−1. This result implies that the optimized reaction condition derived by comparing the various indicators such as conversion of reactants, yield of products, energy consumption, and thermal efficiency is suitable for hydrogen production from biogas.

Green hydrogen production from sorption-enhanced steam reforming of biogas over a Pd/Ni–CaO-mayenite multifunctional catalyst

The carbon-neutral application of biogas to produce “green hydrogen” appears to be an attractive solution to ensure the sustainability of energy production. However, the high and variable CO2 content in biogas has limited the development of biogas utilization. Herein, we report that sorption-enhanced steam reforming of biogas (SESRB) provides an efficient way to obtain high-purity hydrogen from biogas with the in-situ removal of CO2. The effect of temperature and CO2 content on CH4 conversion and H2 purity is studied. The results indicate that the content of CO2 does not affect the CH4 conversion and H2 purity in the pre-breakthrough stage of SESRB process. Meanwhile, the performance of long-term stability shows that 98.0 vol% H2 with ⁓97.8% conversion of CH4 in the pre-breakthrough stage is stably obtained over the Pd/Ni–CaO-mayenite-2.8 multifunctional catalyst for 30 SESRB-calcination cycles. The small amount of coke (0.8 wt%) formed during the SESRB reaction can be effectively eliminated by carbon gasification during calcination treatment. The results point out that SESRB is a promising technology for the efficient utilization of biogas to produce high-purity hydrogen.

Sorption-enhanced steam reforming of CH4/CO2 synthetic mixture representing biogas over porous Ni–CaO–MgO microsphere via a surface modified carbon template

Sorption-enhanced steam reforming of biogas (SESRB) provides an efficient way to obtain high-purity hydrogen from biogas. Highly effective bi-functional adsorbent/catalyst materials play a key role in the long-term operation of SESRB process. Here a general template-based approach using carbon microspheres with alkali modification (MCS) as sacrificial templates to synthesize highly effective bi-functional catalyst is reported. FT-IR, XPS and TGA confirm the enhanced adsorption capacity of MCS to metal ions due to the existence of rich oxygen containing functional groups. The amount of the obtained bi-functional catalyst is increased by 14 times after NaOH treatment. Electron microscopy analysis shows the uniformity of composition and the formation of a favorable morphology, including porous structure and separated nanoparticles, are the crucial for yielding high-performance bi-functional catalyst. Due to the excellent stability of the catalyst structure, 92.3 vol % of hydrogen (dry and inert-free gas basis) with 92% CH4 conversion is obtained over the 1Ni–CaMg6-M catalyst for 10 consecutive reaction-desorption cycles.

Valorization of food waste into hydrogen: Energy potential, economic feasibility and environmental impact analysis

Hydrogen gas is widely acknowledged as a significant energy carrier worldwide. Hydrogen gas derived from sustainable sources could be used as an alternative to fossil fuel for electricity generation with zero emission of hazardous pollutants. Food waste valorization to hydrogen is a viable energy source with potential economic benefits. The current study examines the economic viability and environmental effect of producing hydrogen from food waste in China using biogas steam reforming for power generation. The key findings show that the steam reforming of biogas from food waste could produce 221.12 billion kg of hydrogen gas. The quantity of hydrogen gas yield could generate 661.97 TWh of electricity. It was found that the consumption of the available electricity from the hydrogen gas could displace 15,482.26 M liters of diesel fuel combustion. The amount of diesel fuel consumption avoided can reduce global warming by 42,041.90 kt CO2e. It was also discovered that hydrogen has an appealing ecological efficiency of 94.64% when used as a source of energy generation. According to the outcomes of the economic analysis, the food waste to hydrogen project is economically feasible in all of China's provinces. The average hydrogen production cost, return on investment, the payback period is $0.814/kWh, 29.8%, and 7.2 years. This study could provide scientific data for investment and decision-making on ecological sustainability in food waste to hydrogen initiatives in China and other emerging nations with a similar culture.

Comparative techno-economic modelling of large-scale thermochemical biohydrogen production technologies to fuel public buses: A case study of West Midlands region of England

This work presents techno-economic modelling of four thermochemical technologies that could produce over 22,000 tonnes/year of hydrogen from biomass for >2000 public transport buses in West Midlands region, UK. These included fluidised bed (FB) gasification, fast pyrolysis-FB gasification, fast pyrolysis-steam reforming, and steam reforming of biogas from anaerobic digestion (AD). Each plant was modelled on ASPEN plus with and without carbon capture and storage (CCS), and their process flow diagrams, mass and energy balances used for economic modelling. Payback periods ranged from 5.10 to 7.18 years. For operations with CCS, in which the captured CO2 was sold, FB gasification gave the lowest minimum hydrogen selling price of $3.40/kg. This was followed by AD-biogas reforming ($4.20/kg), while pyrolysis-gasification and pyrolysis-reforming gave $4.83/kg and $7.30/kg, respectively. Hydrogen selling prices were sensitive to raw material costs and internal rates of return, while revenue from selling CO2 was very important to make biohydrogen production cost competitive. FB gasification and AD-biogas reforming with CCS could deliver hydrogen at less than or around $4/kg when CO2 was sold at above $75/tonne. This study showed that thermochemical technologies could produce biohydrogen at competitive prices to extend the current use of electrolytic hydrogen-fuelled buses in Birmingham to the wider West Midlands region.

Simulation of steam reforming of biogas in an industrial reformer for hydrogen production

The paper aims to investigate the steam reforming of biogas in an industrial-scale reformer for hydrogen production. A non-isothermal one dimensional reactor model has been constituted by using mass, momentum and energy balances. The model equations have been solved using MATLAB software. The developed model has been validated with the available modeling studies on industrial steam reforming of methane as well as with the those on lab-scale steam reforming of biogas. It demonstrates excellent agreement with them. Effect of change in biogas compositions on the performance of industrial steam reformer has been investigated in terms of methane conversion, yields of hydrogen and carbon monoxide, product gas compositions, reactor temperature and total pressure. For this, compositions of biogas (CH4/CO2 = 40/60 to 80/20), S/C ratio, reformer feed temperature and heat flux have been varied. Preferable feed conditions to the reformer are total molar feed rate of 21 kmol/h, steam to methane ratio of 4.0, temperature of 973 K and pressure of 25 bar. Under these conditions, industrial reformer fed with biogas, provides methane conversion (93.08–85.65%) and hydrogen yield (1.02–2.28), that are close to thermodynamic equilibrium condition.
