Then, the adsorption capacities and isotherms of pure gases CO2 and CH4 on the synthesized zeolite nanoparticles were determined at three temperatures of 288, 298 and 308 K and various pressures from 1 up to 20 bar. Adsorption capacities of CO2 on the nano-sized zeolites NaX were showed to be higher than CH4. The selectivity of CO2/CH4 of the nano-sized zeolites NaX was 5.47 at 288 K and pressure about 20 bar. The results of the experimental data follows the Langmuir-Frendlich adsorption isotherm. Reduction of the particle size from micrometer to nanometer results in increasing the adsorption capacity for carbon dioxide on the X zeolite nanoparticles about 28% (from 5.067 to 6.536 mmol/g) at 288 K and 20 bar.
