Abstract
Provided are methods of making dehydrogenation catalyst supports containing bayerite and silica. Silica-stabilized alumina powder, prepared by spray drying of bayerite powder, precipitating silica in a bayerite slurry with an acid, or impregnation or co-extrusion of bayerite with sodium silicate solution was found to be a superior catalyst support precursor. Catalysts prepared with these silica containing support materials have higher hydrothermal stability than current CATOFIN® catalysts. Also provided is a dehydrogenation catalyst comprising Cr2O3, an alkali metal oxide, SiO2 and Al2O3, and methods of using said catalyst to make an olefin and/or dehydrogenate a dehydrogenatable hydrocarbon.
