Abstract
In this article, the regeneration of different desiccants such as silica gel, activated alumina, and activated charcoal by using parabolic dish collector has been proposed. The regeneration performance is greatly affected by the solar radiation, surface temperature of desiccant, but also depends on the initial moisture content in the desiccant. The adsorption performance depends upon humidity ratio of air and ambient temperature. The results showed that the regeneration rate and the adsorption rate for silica gel were high as compared to activated alumina and activated charcoal. One kilogram of silica gel on dry basis took 120 minutes, 110 minutes for complete regeneration in forenoon and afternoon period, respectively. In the case of adsorption, silica gel took 560 minutes.
