| 摘 要： | 以合成气为原料，采用Cu-Zn-A l和γ-Al2O3构成的双功能催化剂，对使用浆态床一步法合成二甲醚的系统进行模拟研究。液固两相为全混流，气相为活塞流，组分方程使用四阶精度的Runge-Kutta法并结合C++编程进行求解，通过模拟计算，讨论了压力、温度、催化剂浓度对反应转化率、收率以及DME的选择性的影响，从而寻找合适的反应参数，为工业反应器放大设计和优化操作提供依据。

| Abstract: | The synthesis of dimethyl ether(DME) using syngas in a bubble column slurry reactor was simulated.It was assumed that the fluid and the solid phases were mixed completely(CSTR model) and the gas phase was plug flow(PFR model).The ordinary nonlinear differential equations were solved using fourth-order Runge-Kutta integration with automatic step control. The programming language C was used to implement the numerical algorithm.The influences of pressure,temperature and catalyst concentration on the conversion,yield and selectivity of DME were studied.The optimal reaction conditions were obtained,which are useful for engineering scale-up and plant design. |
