Beschreibung
Zusammenfassung:	FIELD: oil processing. SUBSTANCE: method involves mixing alumooxide carrier with boric acid and molybdenum salt solution followed by molding, drying and calcination of granules. The obtained aluminium-boron-molybdenum composition is impregnated with nickel nitrate solution at concentration 110-175 g/l in the presence of phosphoric acid at pH = 3.6-4.5 at 40-60 C. EFFECT: improved method of catalyst producing. 1 tbl-
