Removal of thiophenic sulfur from gasoline by membrane separation process

摘要

Methods for the separation of sulfur compounds from a liquid hydrocarbon mixture using a hydrophilic, non-ionic membrane are provided. The membrane can also be composed of water-soluble material. Preferred membranes include polyvinylpyrrolidone and cellulose triacetate membranes. The liquid hydrocarbon mixture may be light cracked naphtha.
