Abstract

Carbon molecular sieves (CMS) are carbonaceous adsorbents of increasing importance. This paper describes the results of the study concerning the carbon molecular sieves preparation and modification of the pore structure. Molecular sieving properties of various carbons were studied by measuring the dynamic adsorption capacity for carbon dioxide under pressure swing adsorption (PSA) conditions. Separation of carbon dioxide from N2 – CH4 – CO2 mixture and from landfill gas on CMS prepared in a laboratory unit designed for this purpose based on PSA cycle is also reported..
