Adsorption on nonporous and microporous carbons: Experiment, simulation, and theory

icroporous carbons are used for many separation processes including air and water purification. The measurement of nitrogen adsorption isotherms is widely used as a means of characterizing porous carbons. Pressures as low as ;Molecular simulation was used to calculate methane adsorption and diffusion in a 19 A wide carbon slit at temperatures between 60 and 135 K. Layering, capillary condensation, and freezing transitions were observed. Diffusion near the carbon surface is much slower than in the bulk.;Adsorption was measured at pressures as low as...
