Description
The separation of perfluorocarbons, particularly CF₄ and C₂F₆, from N₂ and CO₂ represents a significant challenge in gas treatment systems related to plasma-based technologies and accelerator facilities. Owing to their high chemical stability, low reactivity, and distinct molecular sizes and polarizabilities, conventional separation methods often show limited
efficiency.
This presentation provides a literature-based overview of current approaches for CF₄ and C₂F₆ separation, with emphasis on adsorption and membrane-based technologies. Recent developments in advanced adsorbent materials, including metal–organic frameworks and other porous solids, are discussed alongside emerging membrane materials such as modified polyimides and mixed-matrix membranes. The key separation mechanisms governing selectivity toward CF₄ and C₂F₆ over N₂ and CO₂ are highlighted.
By comparing adsorption- and membrane-driven processes, this overview outlines current limitations and identifies material-design trends that may enable more efficient and selective separation strategies in future applications.
