For a given set of operating conditions, the hydrogen production from biomass gasification can be improved through optimization of the operating parameters and efficiencies. The present approach can predict hydrogen production via biomass gasification in a range of 10–32 kg/s from biomass (sawdust wood). The biomass is introduced to a gasifier at an operating temperature range of 1000–1500 K. Also, 4.5 kg/s of steam at 500 K is used as gasification medium. Results indicate that improvement in hydrogen production from biomass steam gasification depending on the amount of steam and quantity of biomass feeding to the gasifier as well the operating temperature. Over the range of feeding biomass, the hydrogen yield reaches 80–130 g H2/kg biomass while in the operating temperature examined, the hydrogen yield reaches 80 g H2/kg biomass. On mole basis it is found that, in the first range of H2 varies from 51 to 63% in the studied range of feeding biomass in existing 4.5 kg/s from steam while H2 gets to 51–53% in existing of 6.3 kg/s from steam.
