Assessing the Sorption of Methane by Kuznetsk Basin Coking Coal

Abstract

The physicochemical properties of Kuznetsk Basin coal are studied in the laboratory. The composition and specific surface of the coal samples are compared, as well as their adsorption of CO₂ at different pressures and temperatures. In an atmosphere typical of a mineshaft, coal of moderate metamorphic development is characterized by the greatest sorptional potential in dynamic conditions. Current methods permit assessment of the sorptional properties of coking coal, regarded as a coal–methane system.
