Abstract
In order to monitor the greenhouse gases, there is a new focus on substances that can distinguish between no harmful gases rejected to the atmosphere and capture those that must be decreased. The physico-chemical parameters involved in the expression of analytical model are obtained from the adjustments of the experimental data. We observed that this model can be used to characterize the complicated process by the steric parameters. Samples of these parameters are as follows: The number of CO2 molecules captured per binding site of the adsorbent (n(CO2)). The density of receptor sites of the adsorbent (F-M) through the adsorption energies (Delta E-a) associated for the adsorption of CO2 on the molecular sieves, which are related to Ps(1) parameters. The modulus of the obtained adsorption energies from fitting data ranged between 3.99 and 4.38 kJ/mol, confirming that the adsorption in this system is exothermic and it is founded on physisorption process. Furthermore, a meticulous study of the main intrinsic characteristics of the adsorbent to the temperature impact application and ensuring the compatibility between practical and theoretical statistical physics to find the pore size was carried out.
