CO₂ Hydrate Formation Promoted by a Bio-friendly Amino Acid L ‐ Isoleucine

Abstract We prove that L-isoleucine, a bio-friendly amino acid, can be used to greatly increased CO2 uptake kinetics in the formation of CO2 hydrate without stirring. As far as we know, L-Isoleucine is an accelerator that can effectively promotes the formation of CO2 hydrate (the gravimetric capacity achieved to 331 mg g−1 in 1000 min at a concentration of 0.2 wt%). We also provided a preliminary explanation for this promotion mechanism of L-isoleucine by comparing the structure-performance. Our results will provide a reference for exploring the promotion mechanism of CO2 hydrate.
