Summary: In this study, the co-gasification of treated crude glycerol and animal fat was investigated using steam as the gasification agent. The results showed that the use of dolomite as a catalyst promoted the production of a gas rich in H-2 and CO2, and the gasification parameters increased with temperature.

Summary: This study investigated the steam reforming of crude glycerol and animal fat mixtures. The results showed that dolomite was more effective in reducing tar content and producing producer gas with a high hydrogen content. On the other hand, using alumina particles as the bed material resulted in producer gas with a high CO content and lower hydrogen content.

Summary: In this study, the reaction process of PE steam gasification and the formation mechanisms of syngas, especially hydrogen, were investigated using ReaxFF-MD simulation and DFT calculation methods. The results revealed that the gasification process consists of two overlapping stages: PE thermal depolymerization and H2O reforming. The study also provided insights into the role of free radicals in the reaction process and the effects of temperature and water content on product distributions.

Summary: The study investigated the valorization of different waste plastics through pyrolysis and oxidative steam reforming, validating a thermodynamic simulation tool using experimental results. The impact of process conditions on H-2 production and reaction enthalpy was assessed, leading to the determination of optimal conditions for oxidative steam reforming of plastics. The results demonstrated the potential interest of this novel valorization route, achieving H-2 productions up to 25 wt% under autothermal conditions.

Summary: This paper examines the impact of adding PET, separator, and financials on a PE steam gasification plant in Lebanon. The study aims to explore the potential for valorizing plastic wastes while reducing landfilling and generating benefits. A plant model using Aspen Plus is designed to convert plastic waste into syngas. The addition of PET does not significantly enhance the final product compared to using only PE as the input feed. The optimum conditions are determined through sensitivity analyses, with a net present value six times higher than the initial investment and a payback period of two years. Although focused on a Lebanese case study, this research calls for the establishment of sustainable waste and financial policies in similar contexts.

Summary: This study proposes the use of red mud as a catalyst for steam gasification of corn stover to produce high-quality reducing gas. The results show that increasing the reaction temperature promotes the production of CO, CO2, and H2. Fe2O3 promotes gas-phase reactions, while Al2O3 facilitates the production of CH4 and H2. The presence of CaCO3 inhibits certain reactions and reduces the production of H2. Red mud exhibits superior catalytic performance compared to pure Fe2O3.

Summary: In this study, the co-gasification of biomass and plastics was investigated using simulation methods. The results showed that co-gasification can increase the energy conversion rate and reduce the yield of oxygen-containing char. Additionally, the addition of water increased the concentration of hydrogen. The formation pathways of furans and cyclic ketones were determined, providing insights into the crucial reactions in the co-gasification process. This study offers guidance for predicting the overall evolution tendency of steam co-gasification.

Summary: The Mn1.5Cr1.5O4 catalyst showed significantly less coke deposition under ethylene-steam flow, attributed to the presence of active Mn3+ species for coke gasification without affecting ethylene conversion. This suggests that the Mn-Cr-O spinel oxide with higher Mn content may have coke deposition during steam cracking.

Summary: The study conducted continuous gasification tests on a mixture of lignite and solid recovered fuel, evaluating the effects of different operating conditions on syngas quality, tar reduction effectiveness, and H2/CO molar ratio improvement. Results showed that gasification with a SRF/lignite mixture at 800 degrees C was feasible, with the best outcomes achieved using a SRF/lignite ratio of 0.2 wt/wt.

Summary: The addition of Ni-Co-Ca catalysts enhances the efficiency of catalytic pyrolysis and char steam gasification of Yunnan lignite, resulting in increased H2 production. Ni and Co promote coal catalytic pyrolysis by breaking C-H and C-C bonds. The formation of Ni-Co alloy prevents catalyst inactivation due to oxidation, distortion, and carbon deposition. Ca endows char with abundant pore structure, improving the irregular degree of char crystallite structure, and facilitating H2 production through char gasification at high temperatures.

Summary: This study introduces a novel concept of biomass gasification integrated with inline steam co-reforming (BGSCR) to produce H2-rich syngas and eliminate tar formation. Porous biochar materials (PBMs) produced by direct gasification of wheat straw with different gasifying agents were used as catalytic reforming agents and co-reactants for BGSCR process. The highest gas yield, H2 yield, and syngas yield were achieved in the presence of C[10%O2]. In summary, this study presents a promising gasification route for H2-enriched syngas generation and in-situ tar abatement with biochar reutilization.
