Abstract
A method for dehydrogenation of a hydrocarbon, which comprises selectively oxidizing hydrogen in a gas mixture which is obtained by subjecting a feed hydrocarbon to a dehydrogenation reaction in the presence of a dehydrogenation catalyst and which comprises a dehydrogenated hydrocarbon, an unreacted feed hydrocarbon and hydrogen, by contacting the gas mixture with an oxygen-containing gas in the presence of an oxidation catalyst, and further subjecting a hydrocarbon-containing gas obtained by the oxidation reaction to a dehydrogenation reaction, wherein a catalyst comprising a component having platinum and/or palladium supported on a carrier obtained by calcining at least one member selected from the group consisting of tin oxide, titanium oxide, tantalum oxide and niobium oxide, at a temperature of from 800.degree. C. to 1,500.degree. C., is used as the oxidation catalyst.
