METHOD OF ACTIVATING CATALYST OF OIL FRACTION HYDROPURIFICATION Russian patent published in 2009 - IPC B01J37/20 C10G45/08 

FIELD: chemistry.

SUBSTANCE: catalyst is processed with sulphiding agent, which includes sulphur-organic compound and oil fraction, in particular 1.0-2.0%-solution of dimethyldisulphide in Diesel fuel, dimethyldisulphide being introduced into Diesel fuel step-by-step; thermoprocessing of catalyst being carried out as step-by-step increase of temperature within the interval 160-340°C, after which temperature is reduced to 28-290°C, with general activation duration 20-30 hours.

EFFECT: reduction of equipment corrosion with sulphur oxides, obtaining ecologically pure, low-sulphureous Diesel fuel, polycyclic aromatic hydrocarbons in small amount, increasing degree of unlimited hydrocarbons and reduction of gumming-up of main hydropurification catalyst.
