METHOD OF PREPARING CATALYSTS OF SELECTIVE HYDROGENATION OF ACETYLENES AND DIENES FOR PURIFICATION OF OLEFINS AND FRACTIONS THEREOF Russian patent published in 2001 - IPC

FIELD: preparation of catalysts, particularly, purification of olefins and fractions thereof from acetylene compounds. SUBSTANCE: described is method of preparing catalyst of selective hydrogenation of acetylenes and dienes for purification olefins and fractions thereof. Said method comprises impregnating aluminium oxide based carrier with palladium compound, addition of modifying compound, drying and reduction. Carrier is aluminium oxide which is impregnated with modifying element compound selected from group consisting of Na, Mg, Ca, Zn (or mixture) in amount from 1.1 to 2.0 wt.% (calculated for oxide), impregnation of modified carrier is carried out by circulation of palladium compound in organic solvent to palladium content of 0.01-0.5 wt. %. EFFECT: increased catalyst activity, greater process selectivity, and highly dispersed catalyst. 6 cl, 10 ex, 1 tbl
