| titleOfInvention | HYDRAULIC CATALYST OF HEAVY OIL FRACTIONS AND METHOD FOR PREPARING IT |
| abstract | 1. The catalyst for hydrotreating heavy oil fractions containing aluminum oxide, nickel oxide, a compound of molybdenum and silicon, a compound of molybdenum and phosphorus, a compound of tungsten and silicon, a compound of tungsten and phosphorus, characterized in that it comprises active components: [Si · (WO3) 12], in an amount of 1.0-9.0 wt.%; [P · (WO3) 12], in an amount of 1.0-9.0 wt.%; [Si · (MoO3) 12], in an amount of 4.0-22.0 wt.%; [P · (MoO3) 12], in an amount of 6.0-22.0 wt.%; the promoter of the active component is Nickel oxide NiO, in the amount of 3.0-8.0 wt.%; carrier modifiers - V2O5 in an amount of 0.5-5.0 wt.% and SnO2 in an amount of 0.1-4.0 wt.%. ! 2. A method of preparing a catalyst, comprising impregnating the support with an impregnating solution of molybdenum and nickel compounds, characterized in that the synthesis of the modified support is carried out: introducing active components and modifiers into peptized aluminum hydroxide, molding, drying and calcining the obtained extrudates; a single impregnation of calcined extrudates with an impregnating solution containing heteropoly compounds of molybdenum and nickel nitrate, at a pH of between 3.0-5.5, followed by heat treatment of the finished catalyst in an air stream. ! 3. The method according to claim 2, characterized in that heteropolyacids -H4 [Si (Mo12O40)] · 21H2O, Н4 [Р (Mo12O40)] · 14H2O, H4 [Si (W12O40)] · 10Н2О are used as tungsten and molybdenum compounds. , H4 [P (W12O40)] · 10Н2О, and nickel nitrate Ni (NO3) 2 · 6H2O is used as a nickel compound. ! 4. The method according to claim 3, characterized in that the impregnation of the carrier granules is carried out after creating a vacuum in a vessel containing a weighed portion of the carrier and keeping the weighed portion of the carrier in vacuum for 30 minutes (evacuation of the carrier). ! 5. The method according to claim 4, characterized in that the impregnation of the granules of the nose� |
