Abstract

A heat transfer fluid can be used as part of a multi-phase adsorption environment to allow for improved separations of gas components using a solid adsorbent. The heat transfer fluid can reduce or minimize the temperature increase of the solid adsorbent that occurs during an adsorption cycle. Reducing or minimizing such a temperature increase can enhance the working capacity for an adsorbent and/or enable the use of adsorbents that are not practical for commercial scale adsorption using conventional adsorption methods. The multi-phase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment where at least a partial liquid phase of a heat transfer fluid is present during gas adsorption by a solid adsorbent.
