文摘

Clathrate-based CO2 capture was investigated in the presence of thermodynamic promoters. THF, CP, and TBAC demonstrated a significant thermodynamic promotion for CO2 (20%) + N2 (80%) clathrates. The highest gas uptake was observed for the THF (5.6 mol%) solution. TBAC solutions showed the highest CO2 selectivity in the clathrate phase (∼61%). Raman spectroscopy confirmed the guest gas enclathration and clathrate structure.
