Figure 5. The breakthrough curves of the (A) C₃H₈/CH₄ mixtures (v/v = 50/50 under a flow of 2 mL/min); (B) C₂H₆/CH₄ mixtures (v/v = 50/50 under a flow of 2 mL/min); (C) C₂H₄/C₃H₆ mixtures (v/v = 50/50 under a flow of 2 mL/min); (D) C₂H₄/C₃H₆ mixtures (v/v = 50/20 under a flow of 4 mL/min) in an absorber bed packed with Cu-AD-AA at 298 K and 1 bar.
