  • Process for selective hydrogenation of an olefinic feed stream containing acetylenic and diolefinic impurities
    Patent number: 6486369
    Abstract: A process for selective hydrogenation of a C2 and C3 olefinic feed stream containing acetylenic and diolefinic impurities whereby the acetylenes and diolefins impurities are selectively hydrogenated concurrently in a vapor phase process without first separating the C2 and C3 olefinic gases into separate feed stream.
