Periodic heat swing adsorption using direct heat transfer using a heat transfer fluid

摘要

By using a heat transfer fluid as part of the multiphase adsorption environment, the separation of gas components using a solid adsorbent can be improved. The heat transfer fluid can reduce or minimize the temperature rise of the solid adsorbent that occurs during the adsorption cycle. By reducing or minimizing such temperature rise, the working capacity of the adsorbent can be improved and / or impractical for industrial scale adsorption using conventional adsorption methods. It may be possible to use no adsorbent. The multiphase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment in which the liquid phase of the heat transfer fluid is present at least partially during gas adsorption by the solid adsorbent.
