摘要：

为了指导生物质气化合成气的目标组成,为生物质间接液化制取甲醇技术提供必要的理论参考依据,基于Aspen Plus软件平台对生物质基合成气合成甲醇的热力学进行了模拟计算与分析.计算了不同温度、压力和初始组成下反应体系的平衡组成,及其对CO、CO2平衡转化率和甲醇平衡收率的影响.并以4种不同组成的生物质合成气为初始原料,对甲醇合成的热力学分析结果进行了比较.结果表明,降低反应温度增大系统压力有利于生物质基合成气的转化；生物质合成气的初始组成是甲醇合成的重要影响因素,提高原料气中的H2/(CO+CO2)量比比例,降低CO2/CO量比比例,有利于提高甲醇的产量.
Abstract:

A study on thermodynamic simulation of methanol synthesis from syngas, obtained from indirect biomass liquefaction, was presented based on Aspen Plus software to provide theoretical reference. In the analysis of thermodynamics for hydrogenation of CO and CO2, the equilibrium product compositions were investigated in a broad range of conditions such as temperature (160~320  C), reactor pressure (2~8 MPa), molar ratio of H2/ (CO+CO2) (0.5~6), and molar ratio of CO2/ CO (0.2~2) in the feed gas. Meanwhile, the influence of these conditions on CO and CO2 conversion and methanol yield was investigated. Thermodynamic analyses on methanol synthesis from four typical biomassderived syngas were carried out and the results were compared. The results show that lower temperature and higher pressure is in favor of the synthesis of methanol and the composition of feed gas is a key factor to the methanol production. The production of methanol is enhanced, by increasing the molar ratio of H2/ (CO+CO2) or reducing the molar ratio of CO2/ CO.
