a Experimental breakthrough curves for 50/50 mixtures of CO2 and the three C2 hydrocarbons (measured independently) at 293 K and 1.1 bar in an adsorption column packed with MUF-16. b Experimental breakthrough curves for 50/50 mixtures of CO2 and CH4 at 293 K and 1.1 bar in an adsorption column packed with MUF-16. c Twelve separation cycles for a CO2/C2H2 mixture (50/50 mixture). Each separation process was carried out at 293 K and 1.1 bar. MUF-16 was regenerated between cycles by placing it under vacuum at ambient temperature for 20–25 min. d Experimental desorption profile of MUF-16 following the separation of CO2 and C2H2 upon heating under a helium flow of 5 mlN/min at 1.1 bar. No adsorbates were removed upon further heating at 130 °C indicating that they had been fully expelled at lower temperatures. e Experimental breakthrough curves for a 15/80/4/1 CO2/CH4/C2H6/C3H8 mixture at 1.1 bar and 293 K in an adsorption column packed with MUF-16. f CO2 adsorption isotherms (293 K) of as-synthesized MUF-16 after four consecutive adsorption-desorption cycles, after exposing it to air with ~80% humidity for 12 months, and after immersion in water for 48 hours.
