The production of carbon sorbents based on special fine coke using a combination of steam and gas activation (by gas after the carbonization of Shubarkol coal with carbon dioxide and superheated water vapor) and chemical activation (by sodium hydroxide) was studied. Their textural and sorption properties were characterized. The necessity of separating the carbon and mineral parts of the special fine...
The results of a study of carbon materials from rice husk, lignin, and cellulose subjected to different activation processes performed by the BET method and X-ray diffraction analysis are reported. The specific surface areas and total pore volumes and the X-ray diffraction compositions and characteristics of the carbon structures of the test samples were determined. It was shown that the treatment...
