The article presents the results of the study of the adsorption energy, thermodynamic parameters of adsorbents, which serve to solve the problems of ecology and environmental protection.Based on the results obtained, the adsorption mechanism of the pargaz activated carbon adsorbent on the basis of tree wood and waste stem was studied.The energy of the adsorption process of the adsorbent is obtained on the basis of data on the full thermodynamic parameters of the field of application of adsorbents. The paper examines the differential heat content, adsorption isotherm, entropy, and kinetics of PPAU-A experimentally. This article uses adsorption microcalorimetric methods of analysis. Paulownia tomentosa tree coal adsorbents according to the adsorption amounts of water molecules in thermally and steam-gas activated carbon adsorbents based on tree stems is as follows: PPAU-A> BAU-A.The value of the adsorption value of water vapor in PPAU-Ada Beryoze activated carbon was found to be 1.4 times higher than BAU-A.
