METHOD FOR PREPARATION OF THE CATALYST FOR HYDRAULIC PROCESSING OF PETROLEUM FEEDSTOCKS Russian patent published in 2018 - IPC B01J37/03 B01J37/04 B01J37/08 B01J37/32 B01J21/02 B01J23/85 C10G45/50 

FIELD: oil and gas industry.

SUBSTANCE: method for preparation of the catalyst for the hydraulic processing of petroleum feedstocks, which comprises mixing of basic nickel carbonate, of tungstic acid and carrying agent, subsequent extruding of the resulting mass, drying of the extrudates and calcination, is proposed. Boric acid-modified aluminum hydroxide is used – the "raw pastille" is used as a carrying agent, this hydroxide is obtained by means of the single-stream deposition method, which comprises precipitation of aluminum hydroxide from the sodium aluminate solution with nitric acid. Boric acid and aluminum hydroxide – the "raw cake" in terms of absolutely dry matter are taken in the ratio 1:10–56, respectively.

EFFECT: increased mechanical strength, hydrogenating activity, reduced bulk density.
