  • Hydrocarbon conversion catalyst for producing high quality gasoline and C.sub.3 and C.sub.4 olefins
    Patent number: 5358918
    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 C.sub.3 and C.sub.4 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 RE.sub.2 O.sub.3.0.4-1.0 Na.sub.2 O.Al.sub.2 O.sub.3.20-60 SiO.sub.
