摘要： The present invention relates to a cracking catalyst comprising layered clays and a process for cracking hydrocarbon oils using said catalyst. Said catalyst is prepared by the process comprising the following steps: mixing and slurrying an expandable clay, a modifier component, pseudo-boehmite and water for 0.1-10 h to obtain a slurry, aging the slurry at 50-85° C. for 0.1-10 h, then drying and forming the slurry to obtain a formed material, water washing and aging the solid, and finally drying and calcining the solid, and said modifier being one or more selected from the group consisting of hydroxyl polymers of silicon, aluminum, zirconium or titanium, and substances comprising one or more of said hydroxyl polymers. Said process for cracking hydrocarbon oils comprises contacting a hydrocarbon oil with a catalyst under the cracking conditions, said catalyst being the aforesaid cracking catalyst comprising layered clays or a mixture of at least 1% by weight of said cracking catalyst comprising layered clays and a prior cracking catalyst. The catalyst according to the present invention has an improved ability to convert heavy oils. The process according to the present invention for cracking hydrocarbon oils has higher conversion of hydrocarbon oils and higher yield of light oils.
