FIELD: petrochemical industry, method is used in hydrocarbon raw material hydrorefining, during petroleum and natural gas hydrorefining, for desulfurization in particular. SUBSTANCE: aim is to increase hydrolyzing capability of catalyst with high concentration of active components. It is achieved by improvement of known method thermal treatment mode (drying and calcining) of impregnated alumoxide carrier. Method provides for one-stage impregnation of alumoxide carrier with solution of molybdenum, cobalt or nickel compositions and phosphorous with following drying and calcining according to mode. Impregnated carrier is heated from room temperature up to 300 - 350 C for 6 - 8 hours, then it is held under the temperature for 5 - 7 hours, then it is heated up to temperature of calcination for 3 - 5 hours and exercise calcination by known method. EFFECT: increased hydrolyzing capability of catalyst with high concentration of active components. 1 cl, 1 dwg |
