Fluidized catalytic cracking (FCC) catalyst was prepared by a hot acid combined with modified kaolinite as a support material to further explore the influence of modification on the catalytic performance of FCC catalyst. After modification by hot acid binding, kaolinite produces weak B-acid and L-acid sites, and its specific surface area increases from 21.4 m2/g to 44.6 m2/g. Compared with the kaolinite-based FCC catalyst, the performance of the modified kaolinite-based FCC catalyst is significantly improved. The catalytic oil conversion is increased by 1.97%, the heavy oil yield is decreased by 1.62%, and the total liquid yield is increased by 1.54%.
