SELECTIVE HYDROGENATION CATALYSTS CONTAINING PALLADIUM AND AT LEAST ONE METAL OF GROUP IVA Russian patent published in 2002 - IPC

FIELD: catalysts of selective hydrogenation. SUBSTANCE: catalyst has particles of porous carrier which consists of at least one inorganic refractory oxide and active elements in the form of palladium particles distributed over circumference and at least one element M from tin or lead. Catalyst has the following ratio of components, mas.%: palladium, 0.025-1.0; element M, 0.05-4.0; carrier, the balance. Invention also covers method of selective hydrogenation of hydrocarbon fraction of mono- or diolefin hydrocarbons using said catalyst. EFFECT: increased selectivity of hydrogenation process with use of said catalyst. 10 cl, 1 dwg, 9 tbl, 8 ex
