20 Claims

1. A process for catalytically dehydrogenating alkanes to olefins comprising:

providing a supported metal alloy catalyst comprising:

a first metal selected from the group consisting of platinum, palladium, osmium, rhodium, rubidium, iridium, and combinations thereof,

a second metal selected from the group consisting of manganese, vanadium, chromium, titanium, and combinations thereof, and

a support to form a supported metal alloy catalyst, wherein at least some of the metals on the support have a zero valent state;

contacting the supported metal alloy catalyst with a feedstream comprising one or more C₂to C₅₊alkanes; and

dehydrogenating a portion of the one or more C₂to C₅₊alkanes to one or more C₂to C₅₊olefins in the presence of the supported metal alloy catalyst.
