Canadian carbon molecular sieve technology is a process of producing carbon molecular sieves (CMS). CMSs are a class of activated carbons characterized by small pore sizes and a sharp distribution within micropores. These sieves are used for numerous purposes in the petroleum industry. CMSs are utilized primarily to separate and absorb gas mixtures and eliminate gases with specific molecule sizes. Specifically, the sieves are applied in the swing adsorption method to separate gases from each other and other substances. CMSs can also be employed in dehydration and oxidative dehydrogenation processes. For example, gases emitted by fruit and vegetables in the process of decay can be absorbed by CMS membranes to keep them fresh for a more extended period of time.
CMS membranes production technology is a relatively uncomplicated procedure requiring few components. Generally, the sieves are created from the carbonization of polyimide or polymeric precursor membranes under heat treatment using a controlled vacuum. The atmosphere for the procedures has to be chemically inactive to prevent contamination of the CMS membranes. After the heat exposure, the final product contains over 80% of carbon elements, with the remaining elements depending on the composition of polyimide or polymeric precursor films used for the process. As a result, membranes are formed with a bimodal microscope structure, with two distinct pore sizes defined as micropores and ultra micropores. Thus, CMS membranes are highly effective in separating gases with low resistance compared to other molecule sieves.
In summary, CMS membranes are unique activated carbon-based molecule sieves. Unlike other activated carbon films, CMSs possess a distinct bimodal pore size texture, allowing for the separation of gases and such methods as dehydration and oxidative dehydrogenation. Canadian carbon molecular sieves technology is successfully utilized in the petroleum industry and other production processes. Thus, products with the use of CMS membranes are highly effective in performing the separation function.
