Abstract: Research progress of the preparation of coal-based carbon molecular sieve (CMS) absorbents used for gas separation by pressure swing adsorption (PSA) is reviewed in this paper. Different preparation methods and their characteristics related to lignite，bituminous and anthracite coal as raw material are summarized. The effects of main preparation conditions on the structures and separation properties of coal-based CMSs are discussed in detail.
