Steady-state permeation rates for pure COz and CH4 and the binary mixture through homogeneous dense polysulfone and polycarbonate membranes have been measured at 40Β°C and upstream pressures up to 26 atm. The pressure dependence of the mean permeability coefficients for COz and CH, for all of the sys

The side-chain liquid-crystalline polymer (LCP) was synthesized by the addition of the mesogenic monomer to poly (methylsiloxane) with Pt catalyst. When the benzene/cyclohexane mixtures were permeated through the LCP membranes by pervaporation at various temperatures, the permeation rate increased w
Experimental studies have been made on the sorption and permeation of propionic (PA), acetic (AA), and formic (FA) acid in perfluorosulfonic Nafion, and perfluorocarboxylic Flemion membranes.

When a benzene/cyclohexane mixture of 10 wt % benzene was permeated through side-chain liquid-crystalline polymer (LCP) membranes by pervaporation at various temperatures, the permeation rate increased with increasing permeation temperature. The LCP membranes also exhibited a benzene permselectivity
Integrally skinned asymmetric cellulose acetate membranes made by the wet phase inversion for removal of CO 2 from natural gas were investigated. The membrane was cast with the membrane-forming systems of cellulose acetate-acetone and quench media, such as methanol, ethanol and isopropanol, respecti
