高效丙烯助剂KHP在催化装置上的工业应用

中国石油广西石化分公司3.5 Mt/a重油催化裂化装置应用国内某公司生产的高效丙烯助剂KHP。结果表明：系统中高效丙烯助剂KHP质量分数达到5.8 %时，丙烯收率增加1.66百分点，液化气收率增加3.08百分点，汽油收率下降1.75百分点，柴油收率下降1.53百分点，综合商品率基本不变，汽油辛烷值（RON）增加0.5个单位，其它性质基本不变。高效丙烯助剂KHP与主催化剂LDO-75配伍性能良好。

COMMERCIAL APPLICATION OF HIGH-EFFICIENCY PROPYLENE ADDITIVE KHP IN A RFCC UNIT

KHP additive produced by a domestic company was an additive to enhance propylene yield in FCC process.The application of KHP propylene additive was carried out in a 3.5 Mt/a RFCC unit of PetroChina Guangxi Petrochemical Company.Test results showed that when the amount of KHP additive in the total catalyst inventory reached 5.8%,the yields of propylene and LPG increased 1.66 and 3.08 percentage points,respectively;meanwhile,the yields of gasoline and LCO dropped 1.75 and 1.53 percentage points,respectively.The overall light products yield remained basically unchanged.The RON of gasoline increased by 0.5 units with no significant changes observed in other gasoline properties.KHP high-efficiency propylene additive demonstrated good compatibility with the primary catalyst LDO-75 during the test.
