A method of partially oxidizing a feed gas comprises providing a reactor containing a catalyst, providing a gas distributor comprising a body having a plurality of channels therethrough and a plurality of outlets from said channels for distributing gas across the catalyst, feeding the feed gas and the oxygen-containing gas into the gas distributor and allowing the feed gas and the oxygen-containing gas to flow through the gas distributor and out through the outlets into contact with the catalyst. The gas distributor preferably comprises a micro-channel gas distributor, which can be assembled by providing a plurality of etched plates defining flow channels, and stacking and fusing the plates. The reactant gases can be mixed within the gas distributor or maintained separately until they have exited the gas distributor.

Utilization of micro-channel gas distributor to distribute unreacted feed gas into reactors

Catalysts and methods useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) comprise at least one base metal and copper with an optional promoter. The catalyst preferably comprises a base metal and a copper-modified Groups 8, 9, or 10 metal on a support comprising alumina, zirconia, or mixtures thereof. Copper is preferably present in an amount of from about 0.1 to about 1.0 percent by weight of the total catalyst weight. The base metal preferably comprises manganese, chromium, gold, their corresponding oxides, or combinations thereof. The optional promoter preferably comprises platinum, palladium, iridium, rhodium, ruthenium, or any combinations thereof.
