Abstrakt: Biomass gasification is an endothermic process which can be used to produce hydrogen (H2). This study presents a simulation model using ASPEN Plus® to design biomass gasification process with water gas shift reaction (WGSR) to obtain maximum H2. This was done by optimizing the process conditions via. modeling to understand the fundamental of the gasification process. Gibbs free minimization and thermodynamics equilibrium approach was used to find out best operating conditions for H2 production. After conditioning of syngas, WGSR at 200°C was introduced to produce H2 as an alternative fuel. Both steam and CO2 as gasification agents were investigated. The effect of temperature and flowrate of steam and CO2 were optimized in such a way so that no solid carbon produced in the syngas. Higher temperature is favorable while temperature higher than 800°C has an adverse effect on H2 yield. The aim of present study is to determine H2 production per kg of biomass feed and H2 productivity per MWth solar-thermal energy input to the gasification system. [ABSTRACT FROM AUTHOR]
