| titleOfInvention | METHOD FOR PREPARING CATALYSTS FOR DEEP HYDROCLEANING OF OIL FRACTIONS |
| abstract | 1. A method of preparing a catalyst for deep hydrotreating oil fractions, comprising impregnating an alumina carrier with a solution of Group VIII and VI metal compounds, characterized in that a joint impregnating solution is prepared containing a molybdenum compound and cobalt nitrate at a Mo / Co molar ratio of 1.70- 2.30, stabilized with 25.8-35.0 ml of 30% H2O2 per 100 ml of impregnating solution, at a pH of 1.5–5.0, and a single impregnation of alumina is performed, followed by heat treatment. ! 2. The method according to claim 1, characterized in that 10-molybdodicobaltate (III) ammonium (NH4) 6 [Co2Mo10038H4] · 7Н2О, or 6-molybdocobaltate (II) ammonium (NH4) 4 [Co (OH) are used as molybdenum compounds ) 6Mo6O18] · 6H2O, or ammonium 6-molybdonickelate (II) (NH4) 4 [Ni (OH) 6Mo6O18] · 5H2O, and cobalt nitrate Co (NO3) 2 · 6Н2О or cobalt acetate Co (СН3СОО) is used 2 · 4H2O. ! 3. The method according to claim 2, characterized in that the impregnation of the granules of the carrier is carried out after creating a vacuum in a vessel containing a portion of the carrier. ! 4. The method according to claim 2, characterized in that the impregnation of the granules of the carrier after creating a vacuum is carried out by an impregnating solution at temperatures of 20-90 ° C. ! 5. The method according to claim 4, characterized in that the final calcination of the finished catalyst is carried out at temperatures not higher than 400 ° C in an oxidizing or inert environment. |
