“… Furthermore, CC3‐R is capable of separating F 2 , Cl 2 , and Br 2 molecules by a stepwise temperature program because of the marked differences between their desorption behaviors. One of the other advantages of CC3‐R is that atoms or molecules of air does not interfere with adsorption of halogen gases; the earlier simulation studies have shown that CC3‐R captures N 2 , O 2 , H 2 O, CO 2 , CH 4 , and noble gases at low temperatures . The results of experiments confirm that all O 2 , N 2 , CO 2 , Kr, and Xe gases are passed through a column containing CC3‐R with maximum retention time of 65 min .…”
