Abstract
The article shows experiments on heat treatment of coal at the Shoptykol deposit of the Maikuben basin by means of its carbonization and activation. First, carbonization of coal was carried out in an inert atmosphere of argon in the temperature range of 25-700 ° C and then the activation of coal with water vapor at a temperature of 700-800 ° C. With the help of energy dispersive X-ray spectroscopy on an SEM instrument (Quanta 3D 200i) with an attachment for energy dispersive analysis from EDAX, its chemical composition and surface morphology of the samples were determined. The BET method is used to determine the adsorption characteristics of the samples. It was found that the specific surface area and specific pore volume significantly increased as a result of high-temperature coal. Tests on approbation of the obtained activated carbon as an adsorbent for the purification of gas and water.
