摘要
中国石化广州分公司采用物理分级技术对连续重整反应一再生系统卸出的催化剂按照密度进行分级,可将受损后的侏儒球、破碎催化剂从正常催化剂中分离出来,分离后可回用的催化剂积炭量最高为3.43%,能够满足积炭量小于7%的控制指标要求。工业运转结果表明,物理分级技术的催化剂密度分级效果良好,将积炭量不大于7%的催化剂回用,不仅能够满足反应和再生的要求,而且还缩短了再生开工过程中黑烧的时间。
Physical separation technology was applied at the CCR unit of SINOPEC Guangzhou Company for grading withdrawn CCR catalyst based on catalyst density varied with coke content.Non-porous beads and fine catalyst particles were separated from normal catalyst.After separation , the maximum coke content of the usable catalyst was 3.43%, which was lower than the control index of less than 7.0%.The low coke catalyst beads were reused in CCR unit and the operation results showed that the reused catalyst not only well met the requirements of reaction and regeneration , but also shortened the black burning time during the start -up of regeneration system.
