A high temperature catalytic membrane reactor for propane dehydrogenation Z.D. Ziaka, R.G. Minet and T.T. Tsotsis Department of Chemical Engineering, University of Southern California, Los Angeles, CA ~89-1211 (USA) (Received June 1,1992; accepted in revised form September 25,1992)
Abstract Nigh temperature catalytic membrane reactors are attracting renewed interest. This surge in research activity is motivated by the development of good quality ceramic membranes. In this paper, results are presented of a study of the propane dehydrogenation reaction in a membrane reactor utilizing a sol-gel alumina membrane for feed mixtures containing significant amounts of propylene and hydrogen. Yields to propylene are reported which are higher than the corresponding equilib~um yields at the same temperature and pressure conditions. Keywords: ceramic membranes; membrane reactors, diffusion; propane dehydrogenation; hybrid systems
