Abstract
In this work, it was investigated adsorption equilibria of pure oxygen and nitrogen in carbonaceous materials such as an activated carbon (AC), single-walled nanotubes (SWNTs), and Multi-walled nanotubes (MWNTs). The microporous structure of AC was a slit-shaped pore while carbon nanotubes (CNTs) were cylindrical structure. This different pore structure and pore size distribution may be led to difference in selectivity of oxygen to nitrogen. The adsorption capacity of oxygen and nitrogen was in the order AC > SWNTs > MWNTs, while the selectivity of oxygen to nitrogen was SWNTs > MWNTs > AC.
