CATALYTIC COMPOSITION FOR REFINING HYDROCARBON MIXTURES, METHOD FOR PREPARATION THEREOF (OPTIONS), AND METHOD OF HYDROFINING OF HYDROCARBON MIXTURES

摘要

FIELD: petroleum processing catalysts.;SUBSTANCE: invention related to hydrofining of hydrocarbon mixtures with boiling range 35 to 250^оС and containing no sulfur impurities provides catalytic composition containing β-zeolite, group VIII metal, group VI metal, and possibly one or more oxides as carrier. Catalyst is prepared either by impregnation of β-zeolite, simultaneously or consecutively, with groups VIII and VI metal salt solutions, or by mixing, or by using sol-gel technology.;EFFECT: increased isomerization activity of catalytic system at high degree of hydrocarbon conversion performed in a single stage.;40 cl, 2 tbl, 19 ex
