The catalytic properties of non-applied nickel-sulfide catalysts in the reactions of hydrogenation and hydrodesulphurization of coal tar from the coal semi-coking of the Shubarkul field (Republic of Kazakhstan) were studied to obtain data necessary for the intensification of the resin processing technology, increasing the yield and improving the quality of the resulting needle coke. As a feedstock, the resin was used without preliminary dehydration (water content 3.4 %) and distillation in a mixture with the prepared catalyst and the residue of distillation with boiling point above 320°C of oil from the Kumkol field (Republic of Kazakhstan), taken in a mass ratio of 1:1.
