多种组合催化剂在加氢裂化装置上的工业应用

摘要

介绍了中国石油长庆石化公司120万 t/a加氢裂化装置应用多种组合催化剂的生产情况,分析对比了主要工艺条件、产品质量及其分布、装置能耗、催化剂加工量等运行数据.结果表明:美国 UOP公司提供的组合催化剂,中质油收率高达73.51%,但装置能耗高达39.05 kg/t,催化剂加工量为0.734万 t/t;壳牌标准催化剂公司提供的组合催化剂,石脑油收率大于30%,且有利于增产航空煤油,降低柴汽比,装置能耗约为35 kg/t,催化剂加工量约为1.4万 t/t.%The production situation of 1.20 Mt/a hydrocracking unit of Changqing Petrochemical Company,PetroChina,were introduced with various combination catalysts,and the operating data were analyzed including the main technical conditions, product quality and its distribution,unit energy con-sumption and catalyst processing capacity,etc. The results showed that the intermediate oil yield of the combination catalysts provided by the American UOP Company could reach up to 73.51%,but the unit energy consumption could reach up to 39.05 kg/t,and the catalyst processing quantity was 7.340 kt/t.The naphtha yield of combination cata-lysts provided by the Shell Standard Catalyst Compa-ny could achieve more than 30%,and it was benefi-cial to increase production of jet fuel and reduce ra-tio of diesel to gasoline,the unit energy consumption was about 35 kg/t,and the catalyst processing quan-tity was about 14 kt/t.
