Metal-Organic Frameworks (MOFs) are a class of highly promising porous materials with potential applications in the capture and separation of greenhouse gases (GHGs). One of the key considerations in GHG capture technology is the energy efficiency of the process. The objective of this study was to analyze the heat transfer properties of radiators integrated with three types of metalorganic frameworks (MOFs). Specifically, Cu-HKUST-1, Co-MOF-74, and Ni-MOF-74 structures were synthesized in situ on a copper heat exchanger. Direct calorimetric measurements were conducted to determine the heat of adsorption of CO2 and CH4, capturing the dynamic nature of these processes. Simultaneously, CO2 and CH4 adsorption isotherms were obtained using the gravimetric method under laboratory conditions at various temperatures, allowing for the calculation of adsorption enthalpies. In the subsequent research phase, experimental investigations focused on the direct capture of low concentrations of CO2 (0–3%) and CH4 (0–5%) from an air stream, leveraging efficient thermal stimulation of the sorption processes.
