The objective of the present invention is to provide: a catalyst that is for cracking hydrocarbon oils and that can lighten hydrocarbon oils at a low cost and in an efficient manner; and a method for cracking hydrocarbon oils. The catalyst for cracking hydrocarbon oils is characterized by containing: one element (X) selected from the IVA group elements; one element (Y1) selected from the group consisting of the IIIA group elements, the VIA group elements, the VIIA group elements, and the period 4 VIII group elements; and one element (Y2) that differs from element (X) and element (Y1) and that is selected from the group consisting of the IIIA group elements, the VIA group elements, the VIIA group elements, the period 4-6 IVA group elements, and the period 4 VIII group elements. The catalyst is further characterized by the ratio of the amount of element (X) present to the total of the amount of element (Y1) present and the amount of element (Y2) present being 0.5-2.0 inclusive, and the ratio of the amount of element (Y2) present to the amount of element (Y1) present being 0.02-0.25 inclusive. The method for cracking hydrocarbon oils uses the catalyst for cracking hydrocarbon oils. |
