In this work, the temperature dependences of the electrophysical characteristics (electrical capacitance, electrical resistance, dielectric permittivity) were investigated in the range of 293-483 K for coal ash of the Maikuben basin (Kazakhstan) in its initial form, after electromagnetic (EM) and electrical discharge (ED) treatments. The temperature ranges in which the material exhibits both semiconductor properties and metallic conductivity are established. The band gap width (ΔE) was calculated for the studied samples. The measurement results showed that in comparison with the initial ash and ash after the EM treatment, the ash after the ED treatment has the highest values of electrical capacitance and dielectric permittivity and the lowest electrical resistance. Analysis of the research results showed that coal ash after ED treatment seems promising as a prepared raw material for its further thermochemical processing with the extraction of such valuable components as rare metals, silica, alumina, as well as a capacitive material (capacitor) and semiconductor.

“…This leads to the search for new methods for obtaining carbon materials with the required set of properties from cheap types of raw materials, which is an urgent task for science and industry [8]. For example, the cost of adsorbents is 450 times higher than the cost of raw materials with a huge sales market, and the total world production of porous carbon materials is currently about 1 million tons/year [9,10].…”

The paper presents the results of a physicochemical analysis of coke sample from “Euromet” LLP (Karaganda, Kazakhstan), which is a carbonaceous material with high carbon content, the absence of volatiles matter and low ash content. Carbon sorbents were obtained from low-value fractions of carbonized materials of the Karaganda region coke production by the steam-gas activation. An important advantage of using screenings (coke breeze class 0-10 mm, which was crushed and fractionated to a particle size of 2-5 mm.) is the exclusion of the energy-intensive carbonization stage from the technological process, which releases a large amount of environmentally harmful substances (phenols, cresols, gaseous emissions etc.). The optimal conditions for obtaining a sorbent from low-value coke breeze are a temperature of 850 °C and an activation time of 2 hours. The physicochemical properties (ash content, bulk density, sorption capacity for iodine and methylene blue, total pore volume for water) of carbon sorbents were determined
