CATALYST OF SELECTIVE HYDROGENATION, METHOD OF PRODUCTION OF SUCH CATALYST AND METHOD OF SELECTIVE HYDROGENERATION OF ALKYNES WITH THE USE OF SUCH CATALYST Russian patent published in 2005 - IPC

FIELD: catalysts of selective hydrogenation of alkynes of C₄ fractions.

SUBSTANCE: proposed catalyst contains 1-30 mass-% of copper used as first active component, 0.001-5 mass-% of palladium used as second active component, at least 0.001-6 mass-% of one metal selected from Al, Pt, Pb, Mn, Co, Ni, Cr, Bi, Zr and Mo as co-catalyst; the remainder being one carrier selected from aluminum oxide, silicon dioxide and titanium oxide. Method of production of catalyst includes impregnation of carrier calcined preliminarily with solutions of active components depending on their content in catalyst. Alkynes are removed from C₄ fractions enriched with alkynes by means of selective hydrogenation with the use of said catalyst.

EFFECT: enhanced selectivity and stability of catalyst.
