FIELD: chemistry.
SUBSTANCE: invention relates to production of adsorption-activated carbon products. An article with a given shape, made from texolitem, is filled with activated carbon with particle size of 0.5-1.5 mm and subjected to carbonisation while raising temperature at a rate of 4-12°C/min to 850-870°C in the medium of carbon dioxide gas. The product is held at final temperature for 25-35 minutes and activated with steam at 820-840°C until development of maximum sorption pore volume of 0.25-0.50 cm3/g.
EFFECT: high adsorption capacity of the obtained carbon products and low power consumption during production thereof.
