合成气一步法制二甲醚反应工序研究

Study on the Reaction Process of One-Step Synthesis of Dimethyl Ether from Syngas

利用Aspen Plus软件对合成气一步法制二甲醚反应工序进行模拟,分别研究了温度、压力、惰性气体含量、二氧化碳含量对反应器性能的影响。研究发现,温度和压力对反应性能影响最大,在反应条件一定的情况下,适当的调整惰性气体含量及二氧化碳含量能够提高二甲醚产量。模拟结果对合成气一步法制二甲醚工艺设计具有一定的参考价值。

The Aspen Plus software was used to simulate the reaction process of one-step synthesis of dimethyl ether from syngas,and the effects of temperature,pressure,inert gas content,and carbon dioxide content on the performance of the reactor were studied.Research has found that temperature and pressure have the greatest impact on the reaction performance.Under certain reaction conditions,proper adjustment of the inert gas content and carbon dioxide content can increase the production of dimethyl ether.The simulation results have certain reference value for the process design of one-step synthesis of dimethyl ether from syngas.
