摘　　要：FC-86催化剂在某石化企业加氢裂化装置上成功进行了工业应用。FC-86催化剂采用新型混捏技术制备,高效DMY分子筛的创制和低成本氧化铝的应用简化了制备操作单元,提高了L酸酸量、降低了堆密度。对比FC-86催化剂与FC-76催化剂的加氢裂化性能发现:在二者加氢裂化性能相近的前提下,与FC-76催化剂使用周期相比,使用FC-86催化剂的重石脑油收率增加0.62百分点,喷气燃料收率下降0.43百分点,柴油收率保持相当,催化剂装填量下降3.29 t;同时,重石脑油芳烃潜含量下降0.95百分点,柴油十六烷指数提高2.1,喷气燃料烟点提高4.1 mm,尾油质量基本相当。这说明,FC-86催化剂的应用可以有效降低催化剂成本和装填量,具有较好应用效果。FC-86 catalyst has been successfully applied industrially in the hydrocracking unit of a petrochemical enterprise.FC-86 catalyst is prepared by new kneading technology.The creation of high-efficiency DMY molecular sieve and the application of low-cost aluminum oxide simplify the preparation operation unit,improve the amount of L acid and reduce the accumulation density.Comparing the hydrocracking performance of FC-86 catalyst and FC-76 catalyst,it is found that under the premise that the hydrocracking properties of the two are similar,compared with the use cycle of FC-76 catalyst,the yield of heavy nathena using FC-86 catalyst increased by 0.62 percentage point,and the yield of jet fuel decreased by 0.43 percentage point and diesel yield remained equivalent,and the catalyst filling decreased by 3.29 t;at the same time,the latent content of heavy nathra aromatic hydrocarbons decreased by 0.95 percentage point,the diesel cetane index increased by 2.1,the jet fuel smoke point increased by 4.1 mm,and the tail oil quality was basically the same.This shows that the application of FC-86 catalyst can effectively reduce the cost and loading amount of catalyst,and has a good application effect.
