Evaluation of the Prospects of Adsorption Methods for Registration of Greenhouse Gases of Endogenous Origin
The adsorption was studied of methane (CH4) and carbon dioxide (CO2) on microporous adsorbents: activated carbons, Sorbonorit-4 and AUK, La-BTC metal–organic framework structure, and NaX zeolite. Adsorption isotherms of methane and carbon dioxide were obtained at pressures up to 0.12 MPa and temperatures of 213–333 K. Comparative analysis showed that the highest adsorption activity is exhibited by the AUK–CH4 and NaX–CO2 systems. The obtained results will allow us to analyze the main components of greenhouse gases using the method of selective adsorption separation and screening of surface gas composition, which is promising for conducting comprehensive studies of geodynamically active regions, including the Kamchatka Peninsula.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
