FIELD: chemistry.
SUBSTANCE: method for producing an active carbon material includes dissolving a particulate polymer selected from polyurethane, polyamide, polyethylene terephthalate, polymethylmethacrylate, polysulfone or mixtures thereof in concentrated sulfuric acid by ultrasound, forming a paste by mixing the sulfuric acid polymer solution with ground peat and aqueous alkali solution, maturing Paste at room temperature for 5-15 days, moulding, drying, heat treatment without access to air up to 850-1000°C with isothermal holding at the final temperature for 15-120 minutes. After cooling, the material is treated with dilute hydrochloric acid under the action of ultrasound and water. Next, drying and heat treatment of the product with water vapour at 800-880°C for 20-60 minutes.
EFFECT: invention makes it possible to obtain active coals of cylindrical granulation with a diameter of granules of 0,15-2,5 mm, Active carbon materials thicker than 1,2 cm, Increase the mechanical strength of active coal on a peat basis and increase its adsorption activity.
