Abstract
A hydrocarbon conversion catalyst for converting petroleum distillates of different boiling ranges, residue oils, and crude oils, especially the heavy hydrocarbons containing high nickel, into high quality gasoline and C3 and C4 olefins. The catalyst of the invention comprises three zeolitic active components consisting of a rare-earth-containing pentasil type high silica zeolite ZRP, a REY zeolite, and a high silica Y zeolite, in a total content of 10-40 wt % based on the total weight of the catalyst, and the remainder synthetic matrix or semi-synthetic matrix comprising 10-40 wt % silica and/or alumina binder. In the total amount of the active components, zeolite ZRP, REY, and the high silica Y are 3-50, 12-75, and 12-75 wt % respectively. The zeolite ZRP used in the catalyst is characterized in an anhydrous chemical composition of the formula 0.01-0.30 RE2 O3.0.4-1.0 Na2 O.Al2 O3.20-60 SiO2 , a specific X- ray diffraction pattern, a higher adsorption capacity ratio of normal hexane to cyclohexane, and a rare earth ingredient which originates from a rare earth containing faujasite used as seed in the synthesis of the zeolite.
