%X Biomass gasification process has emerged as a clean and efficient way of producing hydrogen. In this report, a biomass gasification model was simulated using Fluent® software, in which a steady state reaction model was established, by incorporating multiple steam gasification reactions. Gasification process is one of the efficient and clean ways to produce hydrogen. During the process, several complex and parallel reactions such as char gasification, watergas shift and methanation reactions occur simultaneously. A reaction model was developed using volumetric reaction model approach in order to predict the hydrogen production from the gasifier. The results shows that the highest hydrogen production will be obtained at temperature 850°C. This is because at temperature higher than 850°C the exothermic water-gas shift and methanation reactions are no longer favorable and the production of hydrogen will decrease. Overall, the prediction of hydrogen production from the reaction model is in good agreement with the experimental data.
