Abstract: The present disclosure relates to gallium-based dehydrogenation catalysts that further include additional metal components, and to methods for dehydrogenating hydrocarbons using such catalysts. One aspect of the disclosure provides a calcined dehydrogenation catalyst that includes a gallium species, a cerium species, a platinum promoter, and a silica-alumina support. Optionally, the composition can include a promoter selected from the alkali metals and alkaline earth metals.

Abstract: The present disclosure relates to dehydrogenation catalysts based on one or more certain group 13 and group 14 elements that further include additional metal components, to methods for making such catalysts, and to methods for dehydrogenating hydrocarbons using such catalysts. One aspect of the disclosure provides a calcined dehydrogenation catalyst that includes a primary species P1 selected from the group consisting of Ga, In, Tl, Ge, Sn and Pb and combinations thereof; a primary species P2 selected from the lanthanides; a promoter M1 selected from the group consisting of Ni, Pd and Pt; a promoter M2 selected from the group consisting of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr and Ba, on a silica-alumina support.
