CATALYST OF OIL FRACTIONS HYDROFINING AND METHOD OF CATALYST PREPARATION Russian patent published in 2000 - IPC

Abstract RU 2147256 C1

FIELD: catalytic chemistry, particularly, preparation of catalysts of oil fractions hydrofining; applicable in oil refining industry. SUBSTANCE: new catalyst containing oxides of molybdenum, nickel and/or cobalt, and aluminum is formed of hollow cylindrical granules with definite outer-inner diameters ratio and distinguished by the fact that catalyst additionally contains silicon oxide. Catalyst contains the following ratio of components, wt. %: molybdenum oxide, 4-8; nickel oxide and/or cobalt oxide, 1-3; silicon oxide, 4-18; aluminum oxide, the balance up to 100; granule outer-inner diameters ratio of 2.7-6.0. EFFECT: increased strength of catalyst protective layer for hydrofining of oil fractions. 2 cl, 1 tbl
