摘　　要：为进一步提高装置产能及相同原料气量条件下的甲醇产量,降低甲醇单耗,对甲醇合成反应原理及运行现状进行了分析,考察了温度、压力、空速、催化剂选择性及气体组分对甲醇产量的影响,并采取了相应的优化措施。通过对催化剂床层温度、装置弛放气量、气体组分等影响因素进行优化,提高了CO和CO_(2)的单程转化率,减少了气体损耗,增强了催化剂选择性,在同样的能耗和气量条件下提高了甲醇产能,减少了副产物生成,大幅提高了装置的运行效益。In order to further improv.e the production capacity of the device and methanol production under the same raw gas volume conditions,and reduce methanol consumption,the principle and operating status of methanol synthesis reaction are analyzed.The effects of temperature,pressure,space velocity,catalyst selectivity,and gas composition on methanol production are investigated,and corresponding optimization measures are taken.By optimizing factors such as catalyst bed temperature,device exhaust gas volume,and gas composition,the conversion rate of CO and CO_(2) is improved,gas consumption is reduced,catalyst selectivity is enhanced,methanol production capacity is increased under the same energy consumption and gas volume conditions,by-product generation is reduced,and the operational efficiency of the device is significantly improved.
