<p><strong>Ground</strong>. Hydrogenation of solid fuels is a universal method for obtaining liquid products, which can be carried out under low hydrogen pressure in relation to the organic mass of oil shale (OMOS) due to the specific structure of OMOS. In this event more than 90% of the organic matter of oil shale can be extracted.</p>
<p><strong>Purpose</strong><strong>:</strong> This article is devoted to the study of the process of hydrogenation of oil shale and a mixture of shale and fuel oil for the production of motor fuel components, assessment of the state and prospects for the application of the method of hydrogenation under low pressure of hydrogen.</p>
<p><strong>Materials and methods. </strong>The objects of the study were the oil shale from the Kenderlyk deposit (Quartz JSC, East Kazakhstan region) and the fuel oil from the Zhanazhol deposit (Aktobe region, Kazakhstan). Hydrogenation was carried out in a rotating autoclave with a volume of 2 liters and on a bench flow unit equipped with a 0.8 L reactor and slurry upgrading (shale liquefaction residues) was processed by pyrolysis in a flow unit with a moving descending layer of heat-transfer medium.</p>
<p><strong>Results.</strong><strong> </strong>According to the results obtained, when increasing the temperature of oil shale hydrogenation from 410 to 440 <sup>0</sup>C at a pressure of 8.0MPa, an increase in gas formation from 10.3 to 12.1 wt.% and hydrogen consumption from 0.8 to 1.5 wt.% is observed, and also the connection of gasoline and diesel fractions increases.<strong> </strong>Increasing the hydrogen pressure from 4.0 to 8.0 MPa leads to increase of the degree of transformation of the organic mass of oil shale by 20% and increase the yield of liquid products (from 40.2 to 50.3 wt.%), gas (6.8 to 10.3 wt.%), water (5.7 to 7.6 wt.%) and the content of gasoline and diesel fuel. Hydrogen pressure above 8.0 MPa has no influence on the process parameters.<strong> </strong>The influence of oil shale concentration, temperature and reaction time on the yield of products of thermocatalytic processing of fuel oil and oil shale has been studied. The optimal reaction conditions are as follows: temperature 415-425 °C, processing time 60 min, and the amount of activating additive (oil shale) 10-12 wt.%. The total yield of distillate fractions reaches 56-59 wt.%.</p>
