PROCESS FOR CRACKING AND TRANSHYDROGENATION OF HYDROCARBON FEEDSTOCK

摘要

A hydrocarbon feedstock (10) is cracked (12), and then the cracker product is compressed (18) and separated (20) into various hydrocarbon fractions including a stream containing hydrocarbons more highly unsaturated than mono-olefins (30). That stream is used for transhydrogenation (56) with at least one paraffin (42, 52) and the products from transhydrogenation (58) are combined with the cracker product before the compression thereof.
