The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. The re-dispersion technique involves the formation and removal of carbonyls with the active metals. The carbonyl formation and removal effectively re-disperses the catalyst metal.

Regeneration of partial oxidation catalysts

Embodiments include a method and apparatus for producing synthesis gas in a catalytic partial oxidation reactor by adding hydrogen to the reactor feed stream.

Production of synthesis gas from a feed stream comprising hydrogen

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&deg; C. and 800&deg; 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.
