Hydrocarbon conversion process

摘要

A process for conversion of paraffinic base petroleum cracking stocks to high octane motor fuels and petrochemical feedstocks in which paraffinic components are separated from the cracking stock to yield a deparaffined fraction which is hydrotreated and catalytically cracked and a paraffin fraction which is separately catalytically cracked whereby improved yields of normally gaseous olefins and normally liquid products including high octane motor fuel components are obtained.
