Using Porous Ceramic Catalytic Converters for Dehydrogenation of Propane in Propylene

Self-propagating high temperature synthesis (SHS) was used to obtain porous cermet membranes based on a mixture of aluminum oxide, silicon carbide, and magnesium oxide powders. The obtained membranes are catalytically active. The surfaces of the open pores in them were modified by rhenium-tungsten active components using the alkoxy method. The highest selectivity in terms of propane (about 60%) is achieved at temperature 600°C. In addition, the optimal conditions for implementing the propane dehydrogenation process is temperature 650°C at which the quite high selectivity for the most important monomers remains with a relatively small contribution of accessory processes.
