Development of a porous catalytic converter for the dehydrogenation of cumene to α-methylstyrene

A porous catalytically active membrane based on α-Al2O3 has been synthesized. Powdered additives of the eutectic composition of magnesium oxide and silicon carbide were introduced with the initial corundum filler to synthesize the membrane frame with high open porosity and physical and mechanical characteristics. Then, pressing was carried out at a pressure of 40 to 70 MPa, followed by sintering in the process combustion mode. Additives Re2O7 and WO3 up to 4 wt. % was introduced into the initial mixture by a simple technological method to impart catalytic properties to the synthesized membrane. The scientific foundations have been developed for creating a technology for one-stage production of catalytically active ultraporous membrane converters effective for the processes of cumene dehydrogenation to α-methylstyrene.
