FIELD: petroleum chemistry, chemical technology.
SUBSTANCE: method involves preparing flow of C2- and C3-olefin raw containing acetylenes, diolefins and some low-molecular light gases taken among the group comprising hydrogen, carbon monoxide and methane. Method involves separation of light gases and C2- and C3-acetylene and diolefin impurities are hydrogenated in a single flow of raw under a catalyst layer by addition of hydrogen to the raw flow to obtain the olefin raw flow containing significantly lower content of C2- and C3-acetylene and diolefin impurities and without significant reducing the amount of C2- and C3-olefins in the raw flow followed by separation of C2- and C3-olefins. Method provides reducing in formation of oligomers, enhanced selectivity in the hydrogenation process.
EFFECT: improved method for hydrogenation.
