Abstract
The article discusses the process of thermal dissolution of the organic mass of coal grade G in anthracene oil. The target products of this process are baking-like products. Baking products are valuable raw materials for the production of carbon fibers, in the production of electrodes and other carbon products. When conducting studies of thermal dissolution of coal grade G, anthracene oil, a product of coal tar processing, was used as a solvent. The final temperature of the thermal dissolution process varied in the range of 350-400 oc. For the preparation of the coal-oil mixture, a ratio of 30% coal grade G and 70% anthracene oil was used. For the resulting baking-like product, its qualitative characteristics were determined. Based on the results obtained, the possibility of using this product is evaluated.
