Patent number: 11021419
Abstract: This disclosure relates to catalysts comprising gallium, cerium, and a mixed oxide support useful in the dehydrogenation of hydrocarbons, to methods for making such catalysts, and to methods for dehydrogenating hydrocarbons with such catalysts. For example, in one embodiment, a catalyst composition includes gallium oxide, present in the composition in an amount within the range of about 0.1 wt. % to about 30 wt. %, cerium oxide, present in the composition in an amount within the range of about 0.1 wt. % to about 15 wt. %, a promoter, M1, selected from Pt, Ir, La, or a mixture thereof, present in the composition in an amount within the range of about 0.005 wt. % to about 4 wt. %, a promoter, M2, selected from the group 1 elements (e.g., Li, Na, K, Cs), present in the composition in an amount within the range of about 0.05 wt. % to about 3 wt. %, and a support, S1, selected from alumina, silica, zirconia, titania, or a mixture thereof, present in the composition in an amount within the range of about 60 wt.
