Selective trapping of CO2 gas and cage occupancy in CO2–N2 and CO2–CO mixed gas hydrates

Author affiliations

Abstract

Hydrate-based CO2 trapping from CO2–N2 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 N2-based gas mixtures. Moreover, it is observed that CO molecules would impede hydrate formation from ice when a CO-enriched gas mixture is considered.
