摘　　要：以秸秆为研究对象,利用Aspen P lus软件建立气化反应器模型,对生物质气化制氢进行模拟计算.探讨不同反应条件,包括气化温度、生物质与蒸汽质量配比以及催化剂对富氢气体成分的影响.计算结果表明,未加催化剂条件下,采用生物质蒸汽气化技术可获得体积分数为6000/以上的富氢燃料气,增大蒸汽与生物质质量配比有利于氢气产率的提高;添加CaO、MgO催化剂可较大幅度地提高氢气产率,氢气体积分数最大可达到9400/,其中CaO对生物质气化制氢过程的催化作用非常显著.Simulation of hydrogen generation from biomass catalytic gasification is carried out, using Aspen Plus software to establish the model of gasifier. The gasification parameters including gasification temperature, and ratio of steam to biomass, and catalyzer,their effects on the composition of fuel gas are discussed. The results show that biomass steam gasification can obtain more than 60% hydrogen-rich gas, and the hydrogen yield is improved by increasing amount of steam. The hydrogen yield can be improved greatly by catalytic gasification using calcium oxide and magnesia. The hydrogen concentration can reach more than 94%, where the calcium oxide plays an important role.
