Abstract
This disclosure relates to catalyst compositions including gallium and a zirconium-based mixed oxide support, to methods for making such catalysts, and to methods for dehydrogenating hydrocarbons with such catalysts. For example, in one embodiment, a catalyst composition includes a mixed oxide support comprising at least about 50 wt. % of zirconium oxide, the mixed oxide support being present in the composition in an amount within the range of about 40 wt. % to about 99.9 wt. %; and disposed on the support, gallium, present in the composition in an amount within the range of about 0.1 wt. % to about 30 wt. %, calculated as Ga2O3 on a calcined basis.
Claims14
A calcined dehydrogenation catalyst comprising a mixed oxide support comprising at least 80 wt. % to 99 wt. % of zirconium oxide and 1 wt. % to 20 wt. % of one or more of lanthanum oxide, silicon oxide and cerium oxide, the mixed oxide support being present in the composition in an amount within the range of 70 wt. % to 95 wt. %;
- and disposed on the support, gallium, present in the composition in an amount within the range of 7.5 wt. % to 30 wt. %, calculated as Ga2O3 on a calcined basis;
- and one or more primary promoters selected from platinum, rhodium, palladium, and ruthenium, present in the composition in an amount within the range of 0.01 wt. % to 0.5 wt. %, calculated as oxide on a calcined basis.
