Abstract

This chapter is concerned with CO2 separation from CO2 + CH4 mixtures by means of gas hydrates. It describes and discusses the laboratory experimentation and the metrics of CO2 separation, which define, for given gas mixture and experimental conditions, the various parameters that describe the efficiency of the capture process. A review is then presented of the few available experimental results obtained with CO2 + CH4 mixtures, emphasizing the role of additives, whether water‐soluble or ‐insoluble molecules. The chapter points out possible directions worth being pursued to enhance this selectivity, such as that consisting in forming hydrate in some moist mesoporous materials. It presents and discusses the performance indicators and some of the routes explored for improving selectivity. These routes combine the use of chemical promoters with “non‐chemical” methods investigated so far mainly for increasing the rate of formation of gas hydrate.
