Abstract
The interaction of GZh + Zh coal concentrate with the anthracene fraction of coking tar is investigated. On that basis, a production technology for materials used in the manufacture of special carbon materials (needle coke, carbon fibers, etc.) has been developed, on the basis of the thermal solution of coking coal. By means of thermogravimetric analysis, differential scanning calorimetry, and X-ray structural analysis, as well as plastometric analysis, it is shown that the pyrolysis of coal is significantly affected by adding 5% of the anthracene fraction, on account of its hydrogen-donor activity. In particular, the quantity and fluidity of the plastic mass are increased; coke formation is shifted to high temperatures (>700°C); and the structure of the solid residue is improved.
