Abstract
A catalytic reactor and membrane separation process is described in which a hydrocarbon feed comprising at least one alkane or alkylaromatic is at least one of dehydrogenated, dehydrocyclized, or dehydrocyclodimerized in first and second reactors. The reaction mixtures are separated in first and second membrane separation zones using first and second small pore microporous inorganic non-metallic membrane with a pore size of less than or equal to 4 Å at a temperature of greater than 500° C. The membrane separation zones are separate from the reactors.
