摘要：In this paper, a FCC co-catalyst for enhancing the light oil production was prepared by the sol-gel method, and its effect on the performance of residue cracking catalysts was evaluated in a CCFFB reactor. The test results indicated that the liquid product yield increased obviously, after the surface of FCC equilibrium catalyst was impregnated with the co-catalyst. The yields of dry gas, slurry and coke decreased, while the diesel yield changed slightly. And the crackability of residue was increased; the rate of coke deposition on catalyst surface was decreased, with the thermal cracking reactions inhibited. All these results showed that the co-catalyst could improve the density of acid sites and change the catalyst acidity, which Could promote to prolong the catalyst activity by depositing the co-catalyst on the surface of FCC equilibrium catalysts.
