The effect of biomass steam gasification for hydrogen production is determined through the type of gasifying agent.The influences of temperature and the mass ratio of steam/biomass on gas composition and the volume fraction ratio of H2/CO in biomass steam gasification for hydrogen production are analyzed.Finally,the effect of biomass steam gasification is analyzed from the perspectives of catalyst type and modification.It is shown that the hydrogen generated by biomass gasification hydrogen production technology with water vapor as gasifying agent has better quality.Moreover,the appropriate gasification temperature and steam/biomass ratio both have a good effect on biomass steam gasification hydrogen production.Traditional metal catalysts can deliver better catalytic effect through modification,and avoid the shortcomings before modification as much as possible.
