| Abstract: | The feasibility of preparation of particulate activated carbon from char of cocoa nut husk by water vapour microwave was studied. Effect of microwave power, activation time and flow rate of water vapour on the quality of activated carbon were investigated. The best technology was obtained as microwave power 700?W, activation time 3?min, and flow rate of water vapour 4.8?ml/min. Experiment showed that iodine value of the activated carbon was 1031?mg/g, decolorizing capacity for methylene blue was 10?mL/0.1g and the yield could be reached 60.8%.Activation time of the process is 60 times as fast as the conventional one, with 2 times of yield as much as the convention. |
