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 CH (3.86 mmol/g) and CH (2.92 mmol/g) at 273 K and 1 bar and is selective over CH. Breakthrough simulations show the potential of urea-CTFs for C2/C1 separation.
C2/C1烃类分离是一个重要的工业过程，它依赖于能源密集型的低温蒸馏方法。使用多孔吸附剂选择性分离这些气体是一种可行的替代方法。已使用1,3 - 双（4 - 氰基苯基）脲合成了高度稳定的共价三嗪框架（尿素 - CTFs）。尿素 - CTFs在273 K和1巴下对CH4的气体吸附量为3.86 mmol/g，对C2H6的气体吸附量为2.92 mmol/g，并且对CH4具有选择性。突破模拟显示了尿素 - CTFs用于C2/C1分离的潜力。
