Abstract
Light paraffinic hydrocarbons are catalytically dehydrogenated using a dehydrogenation catalyst and a polymer-porous solid composite membrane capable of separating hydrogen from the effluent of the dehydrogenation reaction. The polymer-porous solid composite membrane may be, e.g., a porous ceramic material coated with a fluorinated dianhydride-diamine, a fluorinated polycarbonate or fluorinated polysulfone.
