Texture of Bituminous Kuznetsk Basin Coal

The specific surface and porosity of bituminous coal (rank Zh) are studied. The textural characteristics of Kuznetsk Basin coal are determined by various methods: for example, the specific surface by the Brunauer–Emmett–Teller (BET) method; the micropore volume by the comparative t-plot method; and the mesopore volume by the Barrett–Joyner–Halenda method from the low-temperature (77 K) absorption–desorption isotherms obtained by means of a Micromeritics ASAP 2020 instrument. The specific surface is small, and mesopore structure predominates for all the coal samples. Analysis of the pore structure of Kuznetsk Basin coal reveals their macro- and microstructure and provides information regarding their adsorption properties.
