Abstract:
1. A method of converting C 2 and/or higher alkanes to olefins, comprising contacting a feedstock containing C 2 and/or higher alkanes with a first surface of a metal composite membrane of a sintered homogenous mixture of a metal oxide ceramic powder including stabilized or partially stabilized ZrO 2 and a metal powder of one or more of Pd, Nb, V, Zr, Ta and/or alloys or mixtures thereof, wherein the C 2 and/or higher alkanes dehydrogenate to olefins by contact with the first surface with hydrogen from the dehydrogenation of the alkanes passing through the metal composite membrane to a second surface, and separating the formed olefins from the first surface of the membrane while separating the hydrogen from the second surface.
