A study on adsorption of water onto carbon based adsorbents

In the present study, an experimental analysis for adsorption of water onto carbon based adsorbent i.e. activated carbon powder (AC) has been presented. An experimental system has been employed to measure adsorption isotherms of AC and RD type silica-gel with water. Experimental data for AC have been correlated using an appropriate adsorption isotherm model. The isosteric heat of adsorption of the assorted AC/water pair has been extracted from the present experimental data. On the basis of experimental investigation the greenhouse desiccant air-conditioning (DAC) is proposed as an appropriate water-sorption application for AC. A psychometric comparison of AC with silica-gel for greenhouse DAC is given which highlights the importance of carbon-water pair in the adsorption science.
