  • Process for selectively separating hydrogen, or both hydrogen and carbon monoxide from olefinic hydrocarbons
    Patent number: 5907076
    Abstract: A process is disclosed for the separation and removal of hydrogen, alone or together with carbon monoxide, from a mixture of these gases with olefinic hydrocarbons by contacting the mixture with oxygen over a catalyst at conditions sufficient to oxidize the hydrogen to form water while suppressing reaction of the reactive, unsaturated hydrocarbons. The catalyst contains at least one metal or metal oxide from Groups Ib, IIb, IIIa, IVa and Va of the Periodic Table, and the temperature of the reaction may range from about 40.degree. C. to 300.degree. C. and a pressure of about 14.7 psig to 1,000 psig, and the flow rate of the entering feed ranges from about 1 GHSV to about 50,000 GHSV. The process can be conducted using one, two or three reaction zones.
