Abstract:
A process for removing hydrogen from a mixture which includes hydrogen, and unsaturated hydrocarbons which comprises(a) contacting said mixture in a first reaction zone, in the presence of oxygen or an oxygen-containing gas in such an amount that the amount of oxygen present is less than the stoichiometric amount of oxygen required to react with the hydrogen over a catalyst comprising one or more than one of the metals or metal oxides selected from the elements of Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIII of the Periodic Table of Elements at reaction conditions sufficient to oxidize the hydrogen component of the mixture to form water while suppressing hydrogenation of the unsaturated hydrocarbons of the mixture, and removing therefrom an effluent which contains less hydrogen than was present in the mixture,(b) contacting said effluent, in a second reaction zone, over a catalyst at conditions sufficient to react at least some of the hydrogen present with unsaturated hydrocarbon,(c) recovering from said second reaction zone an effluent rich in unsaturated hydrocarbons and denuded of hydrogen.
