摘　　要：某炼厂乙烯装置碳三加氢反应器采用中国石化北京化工研究院自主研发的BC-H-30AG氧化铝浸钯催化剂,通过单段床层液相加氢技术脱除碳三馏分中的MAPD,使丙烯产品中MAPD含量合格,产出合格的丙烯产品。2023年装置开车后,由于催化剂投用初期活性较高,导致副反应较多,副反应产物大量聚合,反应器出口及丙烯精馏塔釜C4、C6含量高,因此通过探讨碳三加氢反应器氢炔比、入口温度、循环量以及反应压力得出最优反应条件,高效实现碳三馏分中MAPD的脱除。BC-H-30AG alumina-impregnated palladium catalyst independently developed by Beijing Chemical Institute was used in the carbon triple hydrogenation reactor of ethylene plant in a refinery.MAPD in carbon triple fraction was removed by single-stage bed liquid phase hydrogenation technology,so that MAPD content in propylene products was qualified and qualified propylene products were produced.After the operation of the unit in 2023,due to the high activity of the catalyst in the early stage of operation,there were more side reactions,and a large number of side reaction products were polymerized.The contents of C4 and C6 were high at the outlet of the reactor and in the propylene distillation tower.Therefore the optimal reaction conditions were obtained by discussing the hydrogen-acetylene ratio,the inlet temperature,the circulation amount and the reaction pressure of the carbon triple hydrogenation reactor,and MAPD removal in the carbon triple fraction was efficiently realized.
