摘　　要：利用Aspen Plus软件,结合吉布斯Gibbs自由能最小化原理,对生物质催化气化过程模拟。考察温度、压力等操作条件及生物质与CaO的配比对气化过程的影响,并结合实验数据对模拟结果进行验证。结果表明:温度升高,产品气中CO和H2以及CH4含量逐渐降低,CO2含量逐渐升高;提高催化剂CaO含量,有利于H2产生;压力升高H2含量增加。总体来说,该模型所得的模拟值与实验值比较吻合。Based on minimization of Gibbs free energy, the process model for biomass catalyzing gasification was developed using Aspen Plus software. The effect of different operating conditions, such as temperature, pressure and proportion of biomass and CaO on gasification process was investigated, and combining with experiment data to verify the simulation results. The results show that contents of CO, hydrogen and CH4 decrease in gas product as temperature increasing, while the content of CO2 increases. As the mass ratio of catalyst CaO to biomass increases from 0 to 0.5, the ratio of hydrogen increases. As pressure increasing, the production of hydrogen increases. Simulation results show that the model is suitable for biomass gasification process, which could provide some reference value for further biomass gasification.
