Recent research published in the journal “Chemical Thermodynamics and Thermal Analysis” has shed light on the thermodynamic functions and parameters related to the sorption of harmful gases, such as carbon dioxide (CO2), sulfur oxides (SOx), and nitrogen oxides (NOx), by a specific type of zeolite known as Khekordzula clinoptilolite. This study, led by Rajden Skhvitaridze from the Faculty of Chemical Technology and Metallurgy at the Georgian Technical University, addresses a critical environmental issue: the greenhouse effect and global warming exacerbated by industrial emissions.
The research highlights the importance of zeolites as adsorbents in carbon capture and gas purification technologies. Khekordzula clinoptilolite, found in the inner Kartli region of Georgia, has not been extensively studied in terms of its thermodynamic properties until now. The study determined key thermodynamic parameters, including the enthalpy of formation and Gibbs energy, which are essential for understanding how this mineral can effectively capture and store harmful gases.
One significant finding is that the chemisorption of these gases begins at temperatures exceeding 2000 K, while physical sorption starts at a much lower temperature of approximately 352.9 K. This suggests that Khekordzula clinoptilolite could be utilized in various industrial applications, especially in processes where high-temperature gas treatment is required.
Skhvitaridze notes, “The results of the conducted studies make it possible to evaluate the prospects of using Khekordzula and natural zeolites of similar composition as an adsorbent for harmful industrial gases.” This opens up commercial opportunities for industries looking to mitigate their environmental impact, particularly in sectors such as energy production, manufacturing, and waste management.
As industries worldwide face increasing pressure to reduce emissions and comply with stricter environmental regulations, the application of Khekordzula clinoptilolite as an effective adsorbent could provide a viable solution. The ability to capture and utilize these gases not only helps in addressing climate change but also presents potential economic benefits through the development of new technologies and processes aimed at sustainability.
This research underscores the value of local natural resources in combating global environmental challenges and highlights the potential for innovation in materials science and engineering. As interest in carbon capture and utilization grows, the findings from this study could pave the way for the development of more efficient and cost-effective solutions to reduce industrial emissions.
