Modified industrial alumina-nickel-molybdenum catalysts manufactured by OOO NZK have been tested in the mode of hydrotreating of heavy vacuum gas oil on a pilot plant of OAO Middle Volga Research Institute of Oil Refining (OAO SvNIINP). A change in hydrocarbon type and structural group composition of gas oils during the hydrogen treatment process has been considered. It has been found that hydrotreating on the GR 24M, NKYu 300, and NKYu 330 catalysts under the examined conditions (340-400°C, 4.0 MPa, 0.5-1 h -1 , hydrogen : feedstock ratio of 500-800 : 1 Nm 3 /m 3 ) leads to a reduction in sulfur, nitrogen, and metal contents of the gas oil and to saturation of polyaromatic compounds with hydrogen, thereby facilitating the further destruction of the feedstock in a catalytic cracker.
