After the coal is removed from the coal mines, it is delivered to the necessary
production industries. Coal dust is formed in coal mines and during transportation for industry.
This does not leave a negative impact on the environment. Today, preventing the
accumulation of coal dust and residues in our Republic and directing it to targeted production
is one of the urgent issues of today. We will be able to determine the full thermodynamic
properties of the obtained porous coal adsorbents by enriching them with additional
substances and determining the adsorption properties of the obtained porous coal adsorbents
using capillary and volume methods in a high vacuum adsorption device and a high-sensitivity
DAK 1-1 calorimetric apparatus. By determining the adsorption isotherm, differential heat,
entropy and equilibrium time of benzene on the obtained coal, it is possible to describe in
detail the adsorption volume, location of active centers, and pore sizes of the new adsorbent
