FIELD: gas treatment.
SUBSTANCE: invention relates to improved method for removing acetylene compounds from hydrocarbon streams, which method comprises bringing hydrocarbon stream containing a first concentration of acetylene compounds and olefins with catalyst being consisted either of supported non-sulfided metallic nickel or the same modified with metals such as Mo, Re, Bi, or mixture thereof, said non-sulfided nickel being present on support in quantity by at least 5% superior to quantity required for selective hydrogenation of acetylenics. Hydrogenation is carried out in first reaction zone at temperature and pressure as well as hydrogen concentration favoring hydrogenation of acetylenics, after which hydrocarbon material is discharged containing second concentration of acetylenics inferior to its first concentration.
EFFECT: improved acetylenics removal selectivity and increased yield of target olefin compounds.
