The paper presents the results of a physicochemical analysis of a coke sample from “Euromet” LLP (Kara-ganda, Kazakhstan), which is 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 exclu-sion 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 condi-tions 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 meth-ylene blue, total pore volume for water) of carbon sorbents were determined.
