3903高活性中油型加氢裂化催化剂的研制

THE DEVELOPMENT OF 3903 HIGH ACTIVE MID-BARREL HYDROCRACKING CATALYST

高活性中油型加氢裂化催化剂3903(工业牌号)是抚顺石油化工研究院“七五”期间研制成功的新一代加氢裂化催化剂,是3824催化剂的替代产品。3903催化剂含钨、镍金属和超稳Y型分子筛。本文总结了3903工业放大催化剂的活性及工业生产催化剂稳定性试验数据并与3824催化剂进行了对比。此外,还考察了3903催化剂对原料油的适应性及较低压力下使用的灵活性。实验结果表明,在相同工艺条件下,3903催化剂反应温度比3824催化剂降低13.5℃,产品分布与产品性质与3824催化剂基本一致,稳定性良好,是一种适应性强、灵活性大的高活性中油型新型加氢裂化催化剂。

The 3903 high activity mid-barrel hydrocracking catalyst, as a substi- tute for 3824 catalyst, is one of the new generation hydrocracking catalysts developed by Fushun Research Institute of petroleum and petrochemicals during the seventh five-year plan period. This paper summarizes the experimental results about activity and stability of 3903 catalyst and compares them with 3824 catalyst. The adaptability of 3903 catalyst to various feedstocks and the flexibility for using under somewhat lower operating pressures are clearly shown. The experiment results demonstrate that, under the same other operating conditions, the reaction temperature of 3903 catalyst is 13.5℃ lower than that of 3824 cata- lyst, while the product distribution and properties are about the same. Besides, the 3903 sta- bility of catalyst is superior. To sum up, the 3903 catalyst is a new-generation high activity mid-barrel hydrocracking catalyst with excellent adaptivity and flexibility for use.
