Rigid Nanoporous Urea-Based Covalent Triazine Frameworks for C2/C1 and CO<sub>2</sub>/CH<sub>4</sub> Gas Separation
C2/C1 hydrocarbon separation is an important industrial process that relies on energy-intensive cryogenic distillation methods. The use of porous adsorbents to selectively separate these gases is a viable alternative. Highly stable covalent triazine frameworks (urea-CTFs) have been synthesized using...

description | C2/C1 hydrocarbon separation is an important industrial process that relies on energy-intensive cryogenic distillation methods. The use of porous adsorbents to selectively separate these gases is a viable alternative. Highly stable covalent triazine frameworks (urea-CTFs) have been synthesized using 1,3-bis(4-cyanophenyl)urea. Urea-CTFs exhibited gas uptakes of C<sub>2</sub>H<sub>2</sub> (3.86 mmol/g) and C<sub>2</sub>H<sub>4</sub> (2.92 mmol/g) at 273 K and 1 bar and is selective over CH<sub>4</sub>. Breakthrough simulations show the potential of urea-CTFs for C2/C1 separation. |
