Phase change material-containing mesoporous zeolite composite for adsorption heat recovery

Abstract : A mesoporous zeolite is proposed as a phase change material (PCM) carrier. Owing to its physicochemical properties, the PCM-containing adsorbent has dual functions, namely simultaneous adsorption, and heat storage. In this study, the mesoporous chabazite-type zeolite SSZ-13, was prepared under various conditions to obtain optimized mesoporous SSZ-13 (MSSZ-13) as a PCM-containing adsorbent. The phase change material was then successfully introduced in the created mesopore space through vapor phase synthesis, and the micropores could be utilized as an adsorption field. The efficiency of the as-prepared PCMcontaining MSSZ-13 was evaluated by a dehumidification process. The afforded experimental results showed suppressed bed temperature ramping, owing to the recovery of the heat generated upon H 2 O adsorption through the PCM. Moreover, the relative amount of adsorbed water increased at the initial period of time-on-stream of the contacting humid fluid.
