Design of PEG ‐Modified Polyethersulfone Membranes With PVA Selective Layer for Efficient Gasoline Desulfurization by Pervaporation
Hydrodesulfurization is used in petroleum refineries to remove sulfur compounds from fuels; however, it requires high temperatures, high hydrogen pressures, and expensive catalysts. Refractory sulfur compounds, including thiophene and its derivatives, are also difficult to remove completely using conventional HDS....
