METHOD OF PREPARING PETROLEUM FRACTION HYDROFINING CATALYST Russian patent published in 2006 - IPC B01J37/02 B01J23/78 B01J23/83 B01J27/19 B01J21/02 

FIELD: petroleum processing catalysts.

SUBSTANCE: catalyst designed for using in petroleum fraction hydrofining, which contains oxides of cobalt, molybdenum, phosphorus, lanthanum, boron, and aluminum, is prepared by mixing aluminum hydroxide with boric acid solution and nitric acid solution of lanthanum carbonate followed by drying, calcination, impregnation of resulting carrier with cobalt nitrate and ammonium paramolybdate solution in nitric acid at pH 2.0-3.5 and 40-80°C in presence of phosphoric acid followed by drying and calcination at elevated temperature.

EFFECT: enabled production of hydrogenate with reduced content of sulfur compounds.
