| 摘 要： | 对于直接以合成气作为原料，使用Cu-Zn-Al和γ-Al2O3构成的双重催化剂、采用浆态床法合成二甲醚的反应体系，使用全混流反应器模型结合化学反应动力学进行模拟。组分方程使用超松弛迭代方法并结合C 编程进行求解，编制了计算机程序。通过模拟计算，讨论了压力、温度、空速、催化剂配比、反应气中不同氢碳比以及CO2含量对反应收率、DME选择性的影响，并讨论了在不同氢碳比下对CO转化率和CO与H2总转化率的影响，从而寻找合适的反应条件，为工业化生产提供参考。

| Abstract: | A complete-mixing-flow-reactor model together with detailed chemical reaction kinetics was used to simulate the synthesis ofdimethyl ether(DME)in a bubble column slurry reactor using syngas directly.The derived non-linear equations were solved using un-der-relaxation iteration method.The programming language C++ was employed to implement the numerical algorithm.The influencesof pressure,temperature and superficial gas velocity in the reactor,catalyst ratio,CO/H_2 ratio and CO_2 content of the feed gas on theconversion,yield and DME selectivity were studied.The influences of different CO/H_2 ratio on CO conversion and total conversionwere also studied.The optimal reaction conditions were found,which can be used as a worthwhile reference for engineering scale-upand design. |
