METHOD OF CATALYST PRODUCING FOR OIL FRACTION HYDROTREATMENT Russian patent published in 1996 - IPC

FIELD: catalysts. SUBSTANCE: method involves the addition of metals of III (rare-earth elements) and VIII (Ni, Mo) groups of periodic system of elements to an oxide carrier followed by drying and calcination. Oxide carrier: gamma-aluminium oxide prepared by precipitation from sodium aluminate solution at molar ratio of aluminium aluminate to aluminium oxide = 1.8-2.0, at concentration 130-150 g/l by aluminium oxide of aluminium sulfate at 40-60 C, pH = 8-10, treatment of fresh-precipitated aluminium hydroxide with rear-earth elements solution at concentration 70-80 g/l by rare-earth elements, pH = 4.0-5.5, at 20-90 C. EFFECT: improved method of catalyst making.
