Catalytic pyrolysis of biomass waste using coal fly ash‐derived ZSM‐5 zeolite for enhanced bioenergy production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy security and sustainability drive the exploration of innovative conversion strategies for abundant biomass waste into energy‐dense products (solid, liquid, and gaseous biofuels). This study demonstrated the catalytic potential of a coal fly ash (CFA)‐derived ZSM‐5 zeolite in enhancing biomass pyrolysis, focusing on lignocellulosic ...

Combustion of pipelineable coal-water slurries

, 1991
The use of liquids or fluids to transport coal through pipelines is not new, nor is the application of coal liquid slurries as fuels in industrial combustion systems. However, it does appear that there are a number of conflicting areas which preclude coals from performing well in a pipeline transportation mode and as a coal-liquid fuel (CLF).

Waste Sawdust‐Derived Hard Carbon Anodes With Engineered Interlayer Spacing for Sodium‐Ion Batteries Exhibiting High Initial Coulombic Efficiency

Carbon Energy, EarlyView.
It is demonstrated that waste sawdust, a green, eco‐friendly, and low‐cost biomass byproduct, can be converted into high‐performance hard carbon through the application of a precisely controlled heating rate. This strategy is optimized and validated through first‐principles calculations, achieving precise control over interlayer spacing and pore ...

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Algebraic model for predicting the hydrodynamics of cocurrent three‐phase fluidized columns

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a novel simplified set of momentum equations to predict the overall hydrodynamics of a cocurrent gas–liquid–solid slurry bed, including phase fractions and pressure drop. The mentioned momentum closures are derived from an idealization of the upward flows within the bed of solid particles, obtained by extending an approach ...
