“…The data obtained in this study agree well with published data on the conversion of the main classes of hydro carbons during the hydrotreating of cat cracking feed stock [9,10,13,16,23]. During hydrotreating, fused (tricyclic or higher) aromatics are primarily saturated with hydrogen.…”

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.

“…As a sulfidizing agent, an intentionally prepared mixture of hydrotreated diesel fuel (280-340°С fraction) with tert butyl polysulfide of the Sulfrazol 54 brand was used. The concentration of sulfur in the mixture was 1.0 wt % [16][17][18].…”
