The adsorption capacity and adsorption kinetics of n-nonane on two carbons and four zeolites have been determined in order to obtain information about the microporous structures present in these solids. In addition thermal desorption of n-nonane has been studied by the Constant Rate Thermal Analysis method. It is observed that hydrocarbon diffusion through pores is the parameter which controls the desorption process. N-nonane adsorption into the micropores of the solids is not a ready process which sometimes exhibits slow adsorption kinetics because of the inaccessibility of the molecules to narrower micropores.
