Abstract

Adsorption of water vapors onto silica-gel and two types of carbon based adsorbents (CBAs) has been experimentally investigated. Adsoption data has been analyzed for various adsorption models. The Guggenhein, Anderson. De-Boer (GAB) and Dubinin-Astakhov (D-A) models gave the good fit for silica-gel and CBAs respectively with an error of less than 5%. The greenhouse air-is proposed the water sorption application for CBAs. Results showed that the CBAs can dehumidify the greenhouse air by utilizing low regeneration temperature and 3-6 times less adsorbent mass as compared to silica-gel. The isosteric heat of adsorption of CBA&Iwater pair does not extremely effect on dehumidification performance.
