Activation temperature and time of briquetted Carbon affect considerably on the properties of active carbon: activity, hardness and burning point. The relations among them were investigated with the following results:-- 1) Activity increases with temperate, and showing a maximum at about 400--450℃, and it decreases gradually 2) Hardness first shows a high value at about 300℃, but suddenly decreases giving a minimum at about 400--450℃, and then steadily increases with the temperature until it reaches to 600℃ or higher. 3) Activation reaction is caused in the range of 400--450℃, though the carbon briquette is weaken in the same range of temperature 4) The higher hardness at 300℃ mentioned above is due to the cementing action of resinous matters of dried briquette 5) The optimum conditions of the process are 2 hours at 600℃.
