摘要

An iso-volumetric test unit was built to test the adsorption and desorption performances of a consolidated composite adsorbent (mixture of CaCl_2 and expanded graphite) with ammonia as the working fluid. The reaction kinetics and heat transfer performance of the consolidated adsorbent were studied and two reaction orders [8/4 and 4/2] were considered in this study. The influences of the refrigerant condensation and activation energy on adsorption performance were analyzed. The thermal conductivity of the consolidate adsorbent was tested by a transient plane source method. Experiment results showed that the liquid condensation phenomenon in the adsorption and desorption process was mainly produced by the condensation of ammonia, which would lead to wrong results of the chemical kinetics; THE maximum error of the kinetic models was about 9.6%, and could meet well the engineering application requirements. The thermal conductivity of the consolidated adsorbent tested in this article was very useful for the selection of a composite adsorbent with good mass and heat transfer performance employed in the adsorption system.
