通过优化工艺条件,严控进料质量、改造循环氢压缩机油系统、调整二甲苯塔操作等措施,使催化剂在运行末期,也能发挥出良好的催化性能,并延长催化剂使用寿命;提高了催化剂处理C10芳烃的能力,降低重芳烃产率,提高经济效益。为催化剂运行末期操作和正常操作提供有益的探索。 By optimizing the process conditions, controlling the feed quality, revamping the circulating hydrogen compressor oil system, adjusting the operation of the xylene tower and other measures, the catalyst can also play a good catalytic performance and prolong the service life of the catalyst at the end of operation; The ability of catalysts to treat C10 aromatics reduces heavy aromatics yields and increases economic efficiency. It provides useful exploration for the operation and normal operation of catalyst.
