多种组合催化剂在加氢裂化装置上的工业应用

Industrial application of various combination catalysts in hydrocracking unit

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 consumption 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. 540 kt/t. The naphtha yield of combination catalysts provided by the Shell Standard Catalyst Company could achieve more than 30% ,and it was beneficial to increase production of jet fuel and reduce ratio of diesel to gasoline, the unit energy consumption was about 35 kg/t,and the catalyst processing quantity was about 14 kt/t.
