Abstract
A new family of oxidative dehydrogenation catalysts having MCrAlY supports can be used in the production of olefins. Olefins are produced by heating a feed stream comprising at least an alkane and an oxidant to a temperature between 25° C. and 800° C.; contacting the feed stream with a catalyst comprising an MCrAlY structure and, optionally, a Group VIII promoter metal coating, wherein M is a base metal, or combination of base metals; and maintaining a contact time of the alkane with the catalyst of less than 200 milliseconds under conditions sufficient to achieve oxidative dehydrogenation of the alkane. M may comprise a metal selected from the group consisting of Group IB-VIIB metals, Group IIIA-VA metals, lanthanide metals, iron, cobalt, nickel, and combinations thereof. More particularly, M may comprise a metal selected from the group consisting Tb, Sm, Pr, Fe, Ni, Co, and combinations thereof.
