Abstract. The paper considers the process of fuel compound production on the basis of light
distillate of coal tar (CT). The analysis of group and individual composition of CT fractions is carried out,
the main components including aromatic hydrocarbons, phenols, heteroatomic compounds and
asphaltenes are revealed, and their physical and chemical characteristics are established. The technique of
stabilisation of mixtures of CT distillate and petroleum fuel oil using a surfactant - acrylic acid - has been
developed. It is shown that surfactant introduction provides a high degree of homogeneity and stability of
fuel compositions, preventing the formation of precipitates even during long-term storage. Optimal ratios
of light distillate and fuel oil (70:30 and 50:50) allow to obtain fuel compounds, the characteristics of
which meet the requirements for boiler and furnace fuels. The obtained results demonstrate the promising
application of light distillate of CT for creation of highly efficient fuel products, which opens new
opportunities for processing of coal-chemical raw materials. The proposed approach contributes to
improving environmental safety, reducing the toxicity of the final product and expanding the raw material
base for fuel production.
