Development of low-cost desiccant systems from biomass-based carbonaceous materials

Part 2 Prediction of dehumidification capacity by activated carbon prepared from botanical wastes

Abstract

The study aims at producing activated carbons from low-cost materials, such as agricultural and botanical waste, without using expensive chemicals. The activated carbons produced by low-cost methods would enhance the possibility of installing desiccant dehumidification in developing countries in hot and humid regions. In this paper, we report dehumidification capacity of activated carbons prepared from Japanese Acorn Nutshell under different preparation conditions based on the water adsorption isotherms. Firstly, the adsorption isotherm equations were generated based on the measured data. Then, the dehumidification capacity was predicted under several ambient air conditions.
