Inorganic membranes and particularly zeolite membranes are usually used for the dehydration of organic solvents by pervaporation (PV). This work reports an experimental study on the PV dehydration of ethylene glycol (EG)/water mixtures using commercial nanoporous NaA zeolite membranes. The concentra
Novel hydrophobic composite membranes made of crosslinked poly(dimethylsiloxane) and poly(methyl hydrogen siloxane) (PDMS-PMHS) with various amounts of catalyst were prepared. Pervaporation experiments with water-ethanol mixtures revealed that an optimum ratio of catalyst to polymer base existed. Bo
