Micro-phase architectural design of fluorinated ethyl cellulose membranes: towards high permeation flux of pervaporation for gasoline desulfurization†
Abstract
A micro-phase architecture of a fluorinated ethyl cellulose membrane was induced by the fluorinated side chains, which disturbs the crystallinity region of EC. The permeation flux of the fluorinated EC membrane for gasoline desulfurization is substantially improved, with just a slight decrease of the sulfur enrichment factor, which greatly improves the efficiency of pervaporation.
