US Freedom Car Partnership. GCMC simulations, using FH quantum
effective potential for fluid-fluid and solid-fluid interactions with
LJ parameters, have shown that CNTs matrices are good hythane
absorbents with important selectivity properties.
Methane storage has also been investigated by GCMC in CMK-1
carbonaceous nanoporous structure in combination with porosim-
etry. The measured isosteric heat values are in a broad range, thus
demonstrating the heterogeneous nature of the investigated materi-
als [81].

Physical Adsorption of Other Gaseous Species in
Carbon Nanostructures
A significant part of the literature concerning the physical adsorption
of gaseous species other than hydrogen and methane in carbonaceous
nanostructures has been devoted to support porosimetry by theory,
especially concerning ACs, MPC, and, in general, disordered porous
structures.

Porosimetry has been often studied in connection with
adsorption and storage to get reliable adsorption volume
measurements. The adsorption isotherms of nitrogen, argon, carbon
dioxide, etc. have been fitted by GCMC at both cryogenic temperature
