一种烃油裂化方法
摘要：
一种烃油裂化方法，包括在催化裂化反应条件下，将烃油与催化裂化催化剂接触，所述催化裂化催化剂含有有效量的分子筛和一种含添加剂的氧化铝，所述催化剂由包括以下步骤的方法制备：(1)将拟薄水铝石与足以使其浆化的水和酸在搅拌下混合，其中酸的用量使所述酸与拟薄水铝石中氧化铝的重量比值为0.01－0.5；(2)将步骤(1)的混合浆液于室温－90℃的温度下老化0－24小时；(3)将步骤(2)的产物与添加剂混合；(4)将步骤(3)的产物与分子筛混合、干燥并焙烧。本发明提供的催化裂化方法具有更高的重油转化能力。
摘要（英）：

This invention discloses a catalytic cracking method for cracking hydrocarbon oil in the presence of a cracking catalyst, which comprises an appropriate amount of molecular sieve, and aluminum oxide containing additive. The cracking catalyst is prepared by: (1) mixing pseudoboehmite, water and acid by stirring to obtain mixed slurry; (2) aging the mixed slurry at room temperature to 90 de.C for 0-24 h; (3) mixing the product of step 2 with the additive; (4) mixing the product of step 3 with the molecular sieve, drying and torrefying. The catalytic cracking method has better heavy oil reforming performance.
