Abstract: The production of petroleum base oils at the global level is accompanied by constantly tightening quality requirements covering both technical and environmental aspects. The article addresses the need for lubricant production in Kazakhstan. Given the current level of environmental and consumer properties of petroleum products in the production of high-quality oils, there is a need to study hydrocatalytic processes for processing crude oil. A comparative characteristic of the dewaxing and catalytic hydrodewaxing processes in the processing of vacuum gas oil from the Atyrau oil refinery with the aim of obtaining high-quality oils is given. The dewaxing of vacuum gas oil produced oils with a viscosity index of 83-86 and a solidification temperature of minus 12 °C. The technology of catalytic hydrodepaffination allows us to produce high-quality special lubricating oils with a viscosity index of 136 and a solidification temperature of minus 21 °C. The conducted studies have demonstrated that this processing of residual hydro-carbon raw materials has a double advantage.: it not only provides excellent base oils, but also generates an additional volume of light fractions. This, in turn, contributes to the expansion of the range of petroleum products produced and a significant deepening of oil refining at the enterprise.
