HYDROTREATING CATALYST IMPREGNATING SOLUTION AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/161949

Kind Code:

A1

Abstract:

A hydrotreating catalyst impregnating solution and a preparation method therefor. The impregnating solution is an aqueous solution prepared from a molybdenum-containing compound, a nickel-containing compound, a phosphorus-containing compound, and a carbonate. The preparation method comprises the following steps: 1) adding the molybdenum-containing compound, the nickel-containing compound, and the phosphorus-containing compound to water, and mixing uniformly; 2) heating to raise the temperature by two steps: in the first step, raising the temperature to 35-60°C and reacting for 0-1.5 hours at a constant temperature, and in the second step, further raising the temperature to 90-110°C and performing reflux for 0-3 hours at a constant temperature, to enable the solute added in step 1) to be completely dissolved, thereby obtaining a blackish green clear and transparent solution. In step 2), the carbonate is added to adjust the pH of the impregnating solution to 2-6. The impregnating solution has high metal content and stable properties, is suitable for long-term storage, and has a high and adjustable pH value; a prepared catalyst has high activity.
