Development of Active Carbon from Soft Coal and Its Adsorbing Characteristic

This article presents of a research the technical process of developing grain active carbon from soft coal as raw material and a discussion of the influence of technmnical conditions covering the temperature and time for activation of raw soft coal and production ratio of active carbon upon its adsorbing characteristic.The experimental results indicate that the optimal technical conditions are:granularity of coal made active catbon is 180,the dosage of the felt is 30% of the raw material powder and the carbonization temperature is form 560 to 600 centigrade degrees while the appropriate activation temperature from 850 to 900 degrees centigrade.The article also deals with the efficiency and mechanism of removing water contamination by active carbon.
