Steam gasification of carbon: Catalyst properties [PDF]

, 1991
This research uses three techniques to study catalyzed gasification of carbon in an effort to determine the concentration of catalyst sites on a carbon surface and thus determine how effectively a catalyst is utilized for steam gasification. Both alkali and alkaline earth oxides are effective catalysts for accelerating the gasification rate of coal ...

Hydrogen-rich syngas production from oxy-steam biomass gasification in a fluidized bed reactor: influence of gasification conditions and bed materials

Energy Conversion and Management: X
This study investigates hydrogen-rich syngas production from woody biomass via oxy-steam gasification in a 20 kW fluidized bed reactor. It finds the optimal conditions for gasification by varying the equivalence ratio and steam-to-biomass ratio from 0.19

Biomass char gasification for hydrogen production: A thermodynamic equilibrium analysis

Fuel Processing Technology
Hydrogen can be produced from biomass via thermochemical conversion, either through direct gasification of raw biomass or a two-step process involving pyrolysis to generate char, followed by char gasification. The latter process reduces tar contamination

Thermodynamic Analysis for Gasification of Thailand Rice Husk with Air, Steam, and Mixed Air/Steam for Hydrogen-Rich Gas Production

, 2010
Thermodynamic analysis of gasification with air, steam, and mixed air-steam was performed over rice husk to determine the optimum conditions (i.e., equivalence ratio (ER), steam to biomass ratio (SBR) and operating temperature) that can maximize the ...
