Abstract

In this article, mechanical behavior under compression loads of an innovative adsorbent material, based on silicone compositefoams filled with SAPO 34 zeolite, is presented. The innovative composite foams were obtained profiting by the dehydrogenativecoupling of siloxane constituents. These new adsorbent systems have been proposed to overcome to the low mechanical stabilityof conventional SAPO-34 coating for adsorption chiller. In this concern, static and cyclic compressive tests at room temperature havebeen carried out. Samples at increasing content of SAPO 34 zeolite were tested to evaluate the influence of the filler content on themechanical behavior of the composite foam. The results showed that the presence of zeolite reduces the elastic limit of the foam andincreases the strength. The foams evidenced also acceptable mechanical stability to cyclic compressive loads. The encouraging resultsconfirm the possible use of these new composite foams as adsorbent materials for cyclic adsorption heat pumps
