This paper has provided an effective method to utilize the filter residue. A Y zeolite-containing composite and a fluid catalytic cracking (FCC) catalyst had been successfully prepared by an in-situ crystallization technology using filter residue and kaolin as raw materials. The samples were characterized by XRD, FT-IR, SEM, and N-2 adsorption-desorption techniques and evaluated in a bench FCC unit. In comparison to the reference samples synthesized from single kaolin, the silica/alumina molar ratio, the external surface area, and the total pore volume of the composite increased by 16.2%, 14.5%, and 16.2%, respectively. The catalyst possessed more meso-and macro-pores and more acid sites than the reference catalyst, and exhibited better coke selectivity. The prepared catalyst had the optimum isomerization and aromatization performance. The olefin content in the cracked gasoline obtained over this catalyst was reduced by 5.05 percentage points with the research octane number of gasoline increased by 0.5 units.
