Patent ID: 7122493

Claim:
A process for treating a hydrocarbon feedstream comprising simultaneously contacting the feedstream under cracking conditions with a catalyst system comprising (1) at least one molecular sieve, (2) at least one metal-based component comprised of (i) at least one of oxygen and sulfur; (ii) one or more elements from Groups 5–15 of the Periodic Table of the Elements; and (iii) one or more elements from at least one of (a) Groups 1–2 and (b) Group 4; of the Periodic Table of the Elements; and (3) at least one of at least one support, at least one filler and at least one binder, wherein the hydrocarbon feedstream is cracked and the resultant hydrogen simultaneously combusted, said process further characterized by anaerobic selective hydrogen combustion, wherein the yield of hydrogen is less than the yield of hydrogen when contacting said hydrocarbon feedstream with said molecular sieve component alone under said catalytic reaction conditions, to produce liquid and gaseous hydrocarbons.
