The Dubinin-Radushkevich (DR) equation is widely used for description of adsorption in microporous materials, especially those of a carbonaceous origin. The equation has a semi-empirical origin and is based on the assumptions of a change in the potential energy between the gas and adsorbed phases and a characteristic energy of a given solid. This equation yields a macroscopic behaviour of adsorption...
In this paper, we present a new approach in the preparation of carbon molecular sieves (CMS). Samples of CMS were prepared from macadamia nut shells by a sequence of three stages. First, activated carbon samples were produced by pyrolysis followed by physical activation with carbon dioxide. They were then treated with coke deposition via benzene thermal cracking. It was found that coke deposition...
