Hydrate-based gas separation is a promising method for CO2 capture from CO2/CH4 gas mixtures, and with improved gas separation efficiency, rate of hydrate formation, and gas uptake, this process has the potential to be taken from the lab scale to industry. In this regard, a significant body of work has been conducted in recent years with the aim to enhance the kinetics of the hydrate-based CO2 capture process. The present study presents a review of the kinetic studies performed on the enhancement of hydrate-based CO2 capture from CO2/CH4 in terms of using additives, porous media, nanofluids, etc. Future research directions are also discussed. The present review aims to aid understanding of the mechanism of the hydrate-based CO2 capture process and to provide references for the development of hydrate-based CO2 capture technology toward industrial applications in the near future.
