The shortage of natural resources in the power industry, combined with their increasing usage, price, and negative impact on the environment necessitate the search for new techniques of producing liquid fuel. One such possibility is the production of fuel and chemical products from coal via hydrogenation. The transformation of coal into liquid fuel is a complex technical process that requires saturating the initial substance with oxygen. Therefore, the purpose of this study is to determine the optimal conditions for the catalytic hydrogenation of a mixture of coal, primary coal tar (PCT) and heavy oil residues with an end-boiling point of 300°C. The results show the optimal conditions for producing liquid fuel. The proposed technique allows achieving a complete homogenization of all components and producing a highly stable coal paste. This technique also allows significantly reducing the negative impact on the environment.
