ABSTRACT:
Dehydrogenatable hydrocarbons may be subjected to a dehydrogenation reaction in which the hydrocarbons such as ethylbenzene are treated with a dehydrogenation catalyst comprising a modified iron catalyst in the presence of steam. The reaction mixture containing unconverted ethylbenzene, styrene, hydrogen and steam is then contacted with an oxidation catalyst in a second zone whereby hydrogen is selectively oxidized to the substantial exclusion of oxidation of the hydrocarbon. The selective oxidation catalyst which is employed will comprise a noble metal of Group VIII of the Periodic Table, a metal of Group IVA and, if so desired, a metal of Group IA or IIA composited on a porous inorganic support such as alumina. The noble metal of Group VIII of the Periodic Table will be present in the exterior surface of the support which possesses a depth in the range of from about 10 to about 300 microns in an average concentration at least 10% than the Group VIII noble metal average concentration in the core of the support.
