โœฆ Synopsis

Adsorption of ethylbenzene and styrene at 1504WC followed by heat treatment at 400ยฐC was tried for controlling diffusivities in micropores of Molecular Sieving Carbon. The amount of carbon deposited after heat treatment is a function of adsorption temperature. Diffusivities of oxygen and nitrogen were measured using the chromatographic method and found to decrease sharply with the small increase of the amount of carbon deposited. The ratio of 02/N2 diffusivities, however, was little affected by this treatment.
