Abstract
The thermal dissolution of 1GZhR coal in model aromatic solvents and industrial polyaromatic solvents is analyzed. The following polyaromatic solvents are considered: coking tar, its anthracene fraction, and petroleum gas-oil. They are employed separately and in different combinations. The degree of conversion of the coal’s organic mass, the material balance, and the composition of the products and gases formed are determined. The efficiency of the solvents based on coal tar and its anthracene fraction is established in terms of the degree of conversion of the coal’s organic mass and the group composition of the products. The extractive products of thermal solution for the individual solvents (except for the petroleum gas-oil) and their mixtures take the form of a solid pitch-like mass (softening temperature 76–118°C). They have a high content (90–94%) of quinoline-soluble polyaromatic materials.
