In this paper,Aspen Plus process simulation software was used to compare the effects of adding CO2 adsorbent on hydrogen production by steam reforming of biomass under different conditions[gasification temperature,mass ratio of water to carbon in biomass(S/C),reaction pressure].Based on the energy consumption and material consumption required for producing hydrogen per unit volume,the matrix analysis method was used to optimize,and the best conditions of adsorption enhanced biomass steam reforming gasification were obtained:When the gasification temperature is 500℃,S/C=2 and the gasification pressure is 0.1 MPa,under this condition,the hydrogen production is 1.56 m3/kg,the hydrogen concentration is 98.3%,and the energy consumption and material consumption required for producing the unit volume of hydrogen are 4.16 MJ/m3 and 0.64 kg/m3,respectively.
