LVR-60B催化剂在燕山渣油催化裂化装置上的应用

COMMERCIAL APPLICATION OF LVR-60B CATALYST IN YANSHAN RESID FCCU

介绍了LVR-60B催化剂在800kt/a渣油催化裂化装置上的工业应用情况。应用结果表明,该催化剂抗磨损性强,单耗为0.49kg/t;流化性能好,在掺减渣率达到75.1％、平衡剂上Ni含量达到11 300μg/g的情况下,微反活性能维持在58％,轻油收率达到67.29％,焦炭产率为10.10％,油浆产率为5.04％,汽油辛烷值高(RON为91.4),但烯烃含量高。

Commercial application of LVR-60B catalyst in the resid FCCU at Yanshan Petro-chemical Company was introduced. The result showed that the catalyst had good performances of fluid-ization and anti-attrition, the catalyst make-up rate was 0. 49kg/t. At a vacuum residue content in the feedstock of 75.1%, the nickel contamination reached 11300μg/g on the equilibrium catalyst, and the MAT activity maintained 58. The light oil yield reached 67. 29 % , and the coke and slurry yields were 10. 10% and 5. 04% respectively. The naphtha RON was as high as 91. 4, however, the olefin content in naphtha was high.
