Biomass gasification plant with steady state and dynamics modelling exhibits promising prospects for the process modelling of the system. Extensive studies are required in understanding the biomass gasification system using extensive values of parameters. Previous works are only focusing on the experiment in isolated pilot plant while process modelling in steady state system and dynamics state system for hydrogen production using oil palm empty fruit kernel using Aspen Plus is another steps forward in using simulation study. Several variables are been identified that able to increase the production of hydrogen however because of limited time and knowledge the research was done focusing on one variable. Temperature has been manipulated to increase the production of hydrogen plus enhance carbon conversion efficiency. It plays an important role in the gasification reaction as it increase the conversion of hydrogen respect to the biomass used. While, increasing steam-to-biomass ratio increases hydrogen and carbon monoxide production hence decreases carbon dioxide and carbon conversion efficiency. Previous papers show the increment from 80.89% to 82.78% as result of increasing the biomass to steam ratio. This project focused on at least achieving the values above as validation of the simulation studies.
