Resumen:
By adsorption of different gases and simulation methods it was studied the characterization of microporous
monoliths in activated carbons from coconut shells in relation to the storage capacity of gases that
present energetic interest. Adsorption isotherms of nitrogen, methane, carbon dioxide and hydrogen at
different temperatures were measured at sub-atmospheric pressures. Additional adsorption isotherms
of methane were performed at room temperature and high pressures (up to 4.5 MPa). A Grand Canonical
Monte Carlo simulation of adsorption on slit pores was carried out for these gases. The simulated data
were adjusted to experimental data to optimize the models. Different parameters such as micropore
volume, pore size distribution and differential isosteric enthalpy of adsorption, were studied and related
to the hydrogen and methane storage capacity for these materials.
