✦ Synopsis

The specific adsorption capacity is independent of the thickness up to layer thicknesses of 15 #rn, and for thicker layers it decreases. At a given specific load the highest pumping speed is obtained with the thinnest layers.

With increasing pressure pumping speed rises at equal absolute load, whereas with equal percentage load a drop is observed. It is possible to regenerate the adsorbent by condensing new layers of carbon dioxide on the charged ones.

H 2 adsorption in carbon nanohorns and nanocones has been simulated at 77 K using the grand canonical Monte Carlo method. The models used for the solid adsorbents were nanosized curved graphene sheets of conical shape with five different apex angles, corresponding to the introduction of 1-5 pentagon
