FIELD: petrochemical and oil refining industries, production of catalysts for oil fractions hydrorefining in particular. SUBSTANCE: oil fractions hydrorefining catalyst preparation method provides for separate settling of sodium aluminate by acid under room temperature and during boiling, following mixing of produced modifications of cold and hot settling aluminum hydroxide under mass ratio of 3:1 - 1:2, washing and moulding of hydroxide or / and produced from it powder of aluminum oxide with addition of 0.5 - 15 % of kaolin, drying and calcination of carrier and application of nickel or cobalt and molybdenum on it by impregnation with solution of the metals compound, drying and calcination of produced catalyst under temperature of 220-240 C. Method allows to produce catalyst with increased denitration activity and strength. In the case its desulfurization activity is at level or over the level of catalyst produced by known method. EFFECT: increased catalyst activity and strength. |
