摘要：

Hydrate-based CO2 trapping from CO2-N-2 and CO2-CO gas mixtures is shown by Raman spectroscopy - the results are of interest for new separation and capture technology. A better trapping efficiency is measured for low CO2 concentrations and N-2-based gas mixtures. Moreover, it is observed that CO molecules would impede hydrate formation from ice when a CO-enriched gas mixture is considered.
