An investigation on the oxygen and nitrogen separation from air using carbonaceous adsorbents
Delavar, M1, Nabian, N2.
Adsorption equilibria of pure oxygen and nitrogen were investigated in two
different carbonaceous adsorbents such as activated carbons (ACs) and Multiwalled
carbon nanotubes (MWCNTs). To improve the surface characteristics of
MWCNTs for adsorption operations, the chemical pretreatment operations were
performed. The equilibrium adsorption of oxygen and nitrogen on adsorbents
were measured at different pressure values ranged from 0 to 50 bar at different
temperatures. Due to the different surface structures of these adsorbents, the
selectivity was different. A comparison between the separation factors of
MWCNTs and ACs showed that oxygen was adsorbed on MWCNTs better than
nitrogen. However, the lowest separation factor obtained was 2.7 for oxygen
and nitrogen adsorption on chemically pretreated MWCNTs demonstrating that
the chemically pretreated MWCNTs enhanced the preferential adsorption of
oxygen to nitrogen.
