Catalysts are essential in gas separation processes as they can selectively interact with specific gas molecules. This selectivity is crucial for separating gases from mixtures. For example, in the separation of carbon dioxide from flue gas, amine-based catalysts can selectively react with CO2, allowing it to be captured and removed from other gases like nitrogen and oxygen. Similarly, in the production of high-purity hydrogen, catalysts can assist in processes like steam reforming and water-gas shift reactions, which separate hydrogen from carbon monoxide and other by-products.
