摘要：
Main regularities in the formation of nanotexture and structure of carbon porous materials and development of pores in Kuzbass anthracites were considered. Basic principles of the production of carbon sorbents for efficient separation of gases such as methane and helium, hydrogen and carbon monoxide, were studied. Sorbents produced from Kuzbass coals were analyzed with the help of gas chromatography, SEM with element analyzer, sorpometry, and gas porometry. The literature data on the size of pores and associates of nanofragments were compared to the width of pores andsize of entrance windows in models of CMS (carbon molecular sieve) nanofragments, which were estimated with the help of quantum chemical modeling in MOPAC/PM-3 semiempirical program. The work resulted in the production of carbon molecular sieves for extraction of hydrogen from gas mixtures and in obtaining the data on the main characteristics of sorbents produced.
