摘要
通过对二甲醚合成过程包含的三个独立反应 - CO+ H2 合成甲醇反应 ( MSR) ,甲醇脱水反应 ( MDR)和水煤气变换反应 ( WGSR)依次组合而成的三个反应体系—— MSR,MSR+MDR和 MSR+ MDR+ WGSR的研究 ,在较宽范围内研究了合成气组成、温度和压力对二甲醚合成过程的影响 ;详细阐述了在反应之间产生的协同效应的优点和不足 ,为二甲醚的动力学研究提供理论指导 .
The roles of three reactions involved in dimethyl ether (DME) synthesis from CO hydrogenation: methanol synthesis reaction (MSR), methanol dehydration reaction (MDR) and water gas shift reaction (WGSR) are studied respectively by thermodynamic calculation. By the foundation of three models, MSR, MSR+MDR, MSR+MDR+WGSR the effects of CO concentration in feed, temperature and pressure on the synergic effect are investigated in a wide range. Some information of the advantages and shortcomings derived from synergic effect is demonstrated to guide the study of kinetics of dimethyl ether synthesis.
