This paper presents the results of assessing the suitability of fossil coal from the Kalewa deposit (Myanmar) based on its petrographic and thermographic analysis for the production of granular activated carbons. According to the vitrinite reflection index and other characteristics, the sample meets the requirements for the raw materials. The thermal decomposition of the sample in nitrogen and air has a similar character, with the main mass loss occurring at temperature range of 350–500 °C. The best results of chemical activation of charcoal by alkaline agents (NaON and KOH) in terms of total pore volume (0.38 and 1.16 cm3/g, respectively) and volumes of sorbing pores (0.31 and 0.52 cm3/g for benzene, respectively), adsorption activity for iodine (624 and 1230 mg/g, respectively) and methylene blue (330 ± 10 mg/g) indicate the possibility of producing activated carbons from it with structural and adsorption properties acceptable for practical use. The study of the porous structure of carbonizate and activate by
low-temperature nitrogen adsorption reveals its significant development under the selected conditions of chemical activation with the achieved specific surface area of 811 m2/g. The work contains an assessment of the effectiveness of the use of the obtained adsorbents in a laboratory-modeled process of sorption purification of coke production water containing phenol, tar, oil and petroleum products, cyanides and inorganic salts. The extreme character of the adsorption kinetics was revealed and it was found that the highest degree of purification from organic pollutants is achieved by intensive mixing of activated carbon with a dose of 0.3 g/l with purified water for 20 minutes.
The researches were carried out using D. Mendeleev Center for collective use of scientific equipment, within the framework of the project No. 075-15-2021-688.
