摘要
以固定床反应器二维非均相数学模型为基础 ,针对国产C30 2低压铜基甲醇合成催化剂 ,考察了反应管管径变化对Lurgi型甲醇合成反应器性能的影响。对于同等体积催化剂装填量 ,随反应管管径的增加 ,催化剂床层的热点温度升高 ,热点位置后移 ,径向温差加大 ,反应器单炉生产能力略呈降低趋势 ,但所需的反应管根数则迅速减少。而反应管管径由于受到催化剂使用温度的限制 ,存在一个上限尺寸 ,对于装填C30 2催化剂的Lurgi炉 ,上限尺寸约为 6 0mm。
Based on the two dimensional heterogeneous mathematical model of a fixed bed reactor, it was investigated that how the reaction tube diameter influenced the performance of Lurgi type reactor for methanol synthesis, loaded with domestic C302 Copper based catalyst. For equal volume of loaded catalyst, with the increase of reaction tube diameter, the hot point temperature and the radial temperature difference of catalytic bed rise, the location of the hot point moves towards the reactor outlet, the production per day of a reactor has a dropping trend, but the number of reaction tube needed reduces rapidly. Because of the limit of catalyst active temperature, the reaction tube diameter has an upper limit, and to the C302 catalyst the upper size is about 60 mm.
