METHOD OF PREPARING PALLADIUM CATALYST FOR HYDROFINING OF HYDROCARBON FRACTIONS TO REMOVE UNSATURATED HYDROCARBONS

摘要

FIELD: petrochemical synthesis catalysts.;SUBSTANCE: invention discloses a method for preparation of palladium catalyst comprising impregnation of alumina carrier with palladium chloride solution in presence of aqueous hydrochloric acid, treatment with reducing agent (hydrogen), washing with water, and drying, said carrier being preliminarily decoked exhausted catalyst containing alumina and group I and/or II, and/or VI, and/or VIII metals and subjected to washing with aqueous hydrochloric or nitric acid and then with water. Exhausted ethylene oxide production catalyst or methylphenylcarbinol dehydration catalysts can also be suitably used.;EFFECT: increased selectivity and activity of catalyst.;2 cl, 2 tbl, 21 ex
