FIELD: petroleum processing and petrochemistry. ^ SUBSTANCE: invention relates to hydrotreatment of different petroleum fractions with high content of straight-chain paraffins to yield product with high content of isoparaffins. Catalyst is prepared on the base of crystalline elemento-alumino-phosphates having specified structure via (i) preparing aqueous reaction mixture containing aluminum source, concentrated phosphoric acid, and one or two sources of substituting element selected from magnesium, zinc, silicon, cobalt, manganese, nickel, chromium, and also organic structuring compound constituting di-n-pentylamine or mixture thereof with other di-n-alkylamines and having following composition (in molar parts): R/Al2O3 0.5-2.0, P2O5/Al2O3 0.8-1.2, MOx/Al2O3 0.05-1.5, and H2O/Al2O3 15-200 followed by (ii)crystallization of thus prepared mixture. ^ EFFECT: increased activity and selectivity of catalyst with regard to formation of desired reaction products and preserved catalyst activity regarding hydrogenation of aromatics. ^ 4 cl, 1 dwg, 14 ex |
