CATALYST FOR HYDROCLEANING OF OIL FRACTIONS Russian patent published in 2017 - IPC B01J27/19 B01J27/186 B01J21/02 B01J21/04 

FIELD: chemistry.

SUBSTANCE: invention relates to catalysts for the hydrotreating of petroleum fractions containing cobalt and/or nickel, molybdenum, phosphorus, sodium and aluminium-supported oxides prepared on the basis of aluminium hydroxide of the "raw cake" grade. In this case, the aluminium hydroxide of the "raw cake" grade is produced by the method of single-flow deposition. The composition of the raw material for preparation of the carrier further comprises aluminium hydroxide powder with the following component ratio, wt %: aluminium hydroxide of the "raw cake" grade: aluminium hydroxide powder 1:1-2.3, respectively. The catalyst has the following chemical composition, wt %: cobalt and/or nickel oxide 3.0-4.5, molybdenum oxide 10.5-15.8, phosphorus oxide 3.0-4.0, sodium oxide 0.01- 0.05, aluminium oxide - the rest up to 100.

EFFECT: increase in hydrodesulfurizing activity, decrease in bulk density, increase in specific surface area, simplification of cooking technology.
