PROCESS FOR TREATING GAS MIXTURES

摘要

A process is described for treating a gas mixture comprising hydrogen, carbon monoxide and one or more olefins, comprising the steps of (i) passing the gas mixture and steam over a first catalyst comprising one or more precious metals selected from Pd and Pt supported on a catalyst support, to form a first gas mixture depleted in olefin and carbon monoxide and enriched in hydrogen, (ii) passing the first gas mixture over a second catalyst comprising a metal selected from Ni, Rh and Ru, to form a treated gas mixture and (iii) recovering the treated gas mixture.
