Adsorption of CO₂ and N₂ on Graphite and Cone Grid

Adsorption is the phenomenon that occurs when a gas is in the presence of any material and is uniquely fit for different elements. Using molecular dynamics simulations, the adsorption of a CO₂ and N₂ mixture on graphite is studied at differing temperatures. Attempts to increase selectivity are made by introducing cones, inverted and upright, on top of the graphite. Results show that at molecules are more easily adsorbed at 300K than 400K and that the presence of the cones decreases selectivity, though upright cones perform worse than inverted cones. Further study at different ranges of temperature and strengths of interactions with the inverted cones should provide useful in determining the most effective way to use adsorption to separate CO₂ and N₂.
