Effect of membrane design on the performance of a packed-bed membrane reactor for propane dehydrogenation
- Univ. of New Mexico, Albuquerque, NM (United States); and others
Propane dehydrogenation to produce propylene is an important process for the production of chemical feedstocks. A catalytic packed bed membrane reactor has the potential to provide higher conversions at lower temperatures by the selective removal of hydrogen from the reactor. Operation at lower temperatures ({approximately}500{degrees}C) is desirable because reaction selectivity for propylene is higher and catalyst deactivation is less of a problem. We are currently investigating the influence of membrane design on the performance of a packed bed membrane reactor for propane dehydrogenation. Membrane designs under investigation include microporous (Knudsen diffusion-type) inorganic membranes, {open_quotes}ultramicroporous{close_quotes} silica-based inorganic membranes (molecular-sieving properties), and composite metal-ceramic membranes composed of nonporous palladium or palladium-silver alloys on porous supports. Results for the different membrane types will be presented with analysis of the influence of membrane permselectivity on packed bed membrane reactor perfomance.
