Abstract

Dehydrogenatable hydrocarbons may be subjected to a dehydrogenation reaction in which the hydrocarbons are treated with a dehydrogenation catalyst such as a modified iron compound in the presence of steam in a multi-catalyst bed system. The reaction mixture containing unconverted hydrocarbon, dehydrogenated hydrocarbon, hydrogen and steam is then contacted with a selective oxidation catalyst such as a noble metal of Group VIII of the Periodic Table, a metal of Group IVA of the Periodic Table and, if so desired, a metal of Group IA or IIA of the Periodic Table composited on a highly porous inorganic support. The oxidation catalyst will selectively oxidize the hydrogen to improve the combustion thereof and supply the necessary heat required for a subsequent dehydrogenation treatment.
