| 摘 要： | 建立了包括液相返混和催化剂颗粒沉降的合成气一步法制二甲醚浆态床反应器的数学模型,模拟计算了空速、原料气组成、反应温度、反应压力等反应条件对反应的影响。计算结果表明,CO转化率和二甲醚的选择性随温度增加、压力增大而提高,在一定温度、压力条件下,CO转化率随空速增大而减小,合成气含有一定量的CO2有利于CO转化率增加。

| Abstract: | A mathematical model for one step synthesis of dimethyl ether from syngas in a slurry bubble column reactor was developed,considering the influence of inert carrier backmixing and the influence of catalyst grain sedimentation.The effects of the space velocity,feed gas composition,temperature and pressure were discussed.The results showed that CO conversion and DME selectivity increased with the increase of temperature and pressure.Under the certain temperature and pressure conditions,the conversion of CO de... |
