The results of experimental studies on the joint hydrogenation (5.0 MPa, 420°C, and natural bauxite from the Turgai deposit as a catalyst) of coal and shale from the Kendyrlyk deposit are presented. It was established that the addition of 15% shale to coal increased the yields of gasoline fractions (12.1–12.8%) and middle distillates (15.6–17.8%), as compared to 10.2 and 13.4%, respectively, obtained upon the liquefaction of coal without shale. The yield of sludge (25.8%) and gas formation (4.1%) with the use of a coal + shale raw material mixture were significantly lower than those in the hydrogenation processing of coal. The results obtained allowed us to consider solid fuels from the Kendyrlyk deposit as potential raw materials for the extraction of chemicals and the production of motor fuel components.
