Abstract
In the article provides a preliminary technical and elemental composition of the feedstock (coal and high-viscosity oil), and also determines the physicochemical properties of the resin of the feedstock. Coal and high-viscosity oil were combined pyrolysis with various oil additives in the range of 5-30%. The experiments were carried out in an aluminum retort at temperatures up to 520 °C, resulting in the following products: tar, pyrolysis gas, and semi-coke. The greatest relative increase in oil and pyrolysis gas yields was observed with the addition of high-viscosity oil, amounting to 20%, which is apparently due to the observed synergy effect based on the interaction of coal and oil fractions during heat treatment.
