Evaluation of ad/desorption dynamics of S-PEEK/Zeolite composite coatings by T-LTJ method

In this work, the adsorption/desorption kinetics of a consolidated bed, for adsorption heat pumps (AHP) application, coated with a new composite adsorbent material based on SAPO- 34 zeolite in a matrix of sulfonated polyether ether ketone was investigated. The heat exchanger was coated by drop casting with a composite zeolite/polymer mixture containing 90 wt% of SAPO-34 powder. The adsorption/desorption kinetics was investigated using the Thermal Large Temperature Jump (T-LTJ) method and compared with results reported in literature
