摘要
中国石油广西石化分公司在3.5Mt/a重油催化裂化装置上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。
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.
