Preparation of Active Carbons for Adsorption Cooling System

Among the gas–solid adsorption processes the active carbon methanol adsorption seems to be interesting for use in thermodynamic systems such as heat pumps and cooling systems. The porous structure of active carbon modified by successive removal of external layers from a particle surface as produced by abrasion in spouted bed, next by demineralization and oxidation was evaluated on the basis of nitrogen adsorption data and those for methanol. The aim of this study was to test the improvement of texture and nature of surface of active carbon for adsorption refrigeration system.
