ABSTRACT:
Dehydrogenatable hydrocarbons may be subjected to a dehydrogenation reaction by treating the hydrocarbons in the presence of a dehydrogenation catalyst comprising an alkaline metal-promoted iron compound. The effluent is then subjected to a selective oxidation step in which the hydrogenation produced from the first reaction is oxidized in preference to the dehydrogenated and unconverted hydrocarbons. The catalyst which is used to effect this selective oxidation comprises a Group VIII noble metal, a Group IVA metal and a Group IA or IIA metal composited on a metal oxide support. The present invention is concerned with the use of a cerium-containing alumina as a support for this selective oxidation catalyst.
