The production of tar pitches and binding agents for the manufacture of high quality carbon materials is considered. The progressive scarcity of coal tar pitch is noted. The necessity of a search for new sources of raw materials and alternative methods for the production of coal tar pitch substitutes is substanti ated. The capabilities of different methods for the thermal and thermochemical processing of coals with the production of pitch like products are considered. The prospects of a low temperature process of the thermal dissolution of coals under mild conditions for the preparation of pitch products in a yield much higher that the yield of pitch upon coking are demonstrated.

“…In addition, impurities present in the coal tar pitch will contribute to the impurities in the anodes. [16][17][18] Although many of the heavy metals can be found in the off-gas, these are captured in the GTC and returned to the cell where they eventually end up in the aluminium metal. Vanadium is considered a catalyst for air burn (ISO 12982-1:2000) and, as such, contributes to excess carbon consumption, although this is debated.…”

“…The coal tar pitch is formed in the coke-chemical production, but has not found widespread use despite the availability to obtain many compounds [3][4][5][6][7][8]. In addition, coal tar and some of its pyrolysis products (soot, pitch) could be applied as a pure reducing agent.…”

The article presents studies on the possibility of using a heavy fraction of coke-chemical resin as a macrocomponent of cladding lubricant, its reducing properties for obtaining copper powder and protecting it from oxidation under the influence of temperature and oxygen in the air. All experiments were carried out using a thermal weighing unit consisting of a vertical tubular furnace, electronic scales. To obtain the kinetic characteristics of the pyrolysis of the resin of JSC "Shubarkulkomir", the dependencies of velocity on time at different temperatures were constructed. The values of the activation energy through the rate constant of the processes for different periods of removal of fractions are calculated. Based on these calculations, mathematical models of the removal of fractions of different periods at 200 and 257 °C. are obtained. To determine the temperature onset and the interval of complete reduction of copper oxide, curves of interaction of the charge components were obtained on a derivatograph (Model: Q-1500D; Manufactured by Paulik and Erdei, Hungary). At the rate of non-isothermal heating of the charge equal to 10 °/min, complete recovery of copper is achieved in the temperature range of 100-360 °C and within 26 min. Further, the resulting copper powder was tested as a composite material. Samples for testing composite powders based on a mixture of copper were made of 45 with a hardness of HRC 40-42. dimensions l x b x h = 10 x 10 x 10 mm. All samples had surfaces of class 8 roughness according to GOST 2789. The control bodies were rollers with d = 40 mm, 15 mm thick, made of 45 steel (GOST 1050) with a hardness of HRC 35-40. Based on the results obtained, it can be assumed that the finest copper films were obtained in the friction pair node, which contributed to a significant improvement in the basic tribotechnical parameters of the tested oil after the introduction of the developed antifriction composites into it.
