Abstract
Provided are carbon molecular sieves produced by treating carbonacious materials with plasma. One of their most important uses is adsorbent for pressure swing adsorption processes, which are widely used for the separation of gases on industrial scales. The carbon molecular sieves meet the strong demand in this field where the performance of the adsorbent used governs the efficiency of gas separation. The carbon molecular sieves of the present invention are particularly effective in separating nitrogen gas from air.
