FIELD: chemistry.
SUBSTANCE: method for preparing a carrier for hydrotreating catalysts based on active alumina is provided, comprising mixing aluminium hydroxide "crude cake" with aluminium hydroxide powder, treating the mixture with an organic acid solution, forming, drying and calcining. Aluminium hydroxide, a "crude cake", is produced by a single-stream precipitation method, which involves the precipitation of aluminium hydroxide from the sodium aluminate solution with nitric acid, and the components are mixed in a ratio (wt %) 1:1-2.3.
EFFECT: decrease in bulk density, increase water absorption, increase mechanical strength, increase the specific surface area, simplify the technology of preparation, reduce material and energy costs and reduce production costs.
