Ion-exchanged commercial-zeolites for O₂ production and CO₂ capture by swing adsorption technology: a brief review

Ion-exchange commercial zeolite, such as Faujasite (FAU), Linde Type A (LTA), Mordenite (MOR) zeolite, stands as a versatile and promising solution for both O₂ production and CO₂ capture, addressing critical challenges in the realms of sustainable energy and environmental preservation. As an adsorbent material with highly selective properties, zeolite excels in gas separation applications. In the context of O₂ production, zeolite's ion-exchange capabilities enable the removal of nitrogen molecules from air, resulting in an enriched oxygen stream suitable for a wide range of industrial and medical applications. The cyclic nature of the process allows for continuous O₂ production without the need for constant input of raw materials. Simultaneously, this exceptional zeolite technology is employed for CO₂ capture, efficiently adsorbing and retaining carbon dioxide molecules from flue gases or other emission sources within its porous structure. By preventing CO₂ release into the atmosphere, ion-exchange commercial zeolite actively contributes to climate change mitigation and carbon footprint reduction. This dual application of zeolite, harnessing its ion-exchange properties for O₂ enrichment and CO₂ capture, underscores its immense potential in driving a greener and more sustainable future, offering a promising pathway towards cleaner energy generation and environmental stewardship.
