摘要

Hydrotreating catalysts based on a tetravalent nickel complex of the (NH4)6 [NiMo9O32]·6H2O composition were tested in the hydrodesulfurization of straight-run diesel fraction isolated from the oil and gas condensate mixture of the Achimov deposit. Prospects for optimizing middle-distillate hydrotreating units are considered. The prepared hydrotreating catalysts showed high hydrodesulfurization activity with a residual sulfur content of up to 5–8 ppm. In terms of residual total sulfur content, the obtained hydrogenation products met the requirements of the Technical Regulations of the Customs Union “On Requirements to Automobile and Aviation Gasoline, Diesel and Marine Fuel, Jet Fuel, and Heating Oil”.
