Abstract: The paper presents methodological aspects of the porous structure parameters measuring on the analyzer ASAP 2020 "Micromeritics" for carbon sorbents obtained from fossil coals. The textural characteristics of the carbon sorbents porous structure are determined, such as specific surface area; total pore volume; micro- and mesopore volume of the samples. The textural characteristics of the carbon sorbents porous structure are calculated from the nitrogen adsorption-desorption isotherms at low temperature (77K). The textural characte-ristics of carbon sorbents were calculated by various methods implemented by ASAP 2020 "Micromeritics" analyzer software (BET, Langmuir, DFT, t-Plot, Dubinin-Radushkevich, Dubinin-Astakhov, MP-method, Norvath-Kawazoe, BJH, Dollimore-Heal).

Key words: Porosity carbon sorbents porous structure analysis adsorption
