METHOD OF OBTAINING AGGREGATED CATALYST FOR HYDROGEN TREATMENT OF OIL FRACTIONS Russian patent published in 2009 - IPC B01J37/04 B01J23/85 B01J23/88 B01J23/883 B01J23/76 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention describes method of obtaining aggregated catalyst for hydrogen treatment of oil fractions. The catalyst is a composition of components in the form of compounds of one VIII group metal and two VIB group metals. Method involves mixing and chemical interaction of components, producing active complex by mechanic and chemical activation of components, which remain in solid state during the whole process performed in aggregates of mechanic and/or hydrodynamic effect, preferably in planetary centrifugal mill, at room temperature for 5-30 minutes, with free pass distance of milling bodies equal to 4.0-5.0 cm, relative collision speed of milling bodies equal to 17-34 m/s, reaction layer thickness for component mix on the surface of milling bodies equal to (0.4-2.6)·10^-2 cm, with further drying, tempering and sulfidation. Active complex is dried for 10-15 minutes.

EFFECT: high-grade purification of oil products from sulfur.
