A Study on the Manufacture of Activated Carbon for Water Treatment

The purpose of this study was to disclose the manufacturing process of activated carbon using coal. It investigated the influences on the physical properties that were manufactured activated carbon by using anthracite coal, bituminous coal under carbonizated and activated condition. The adsorption capacities of organic material were superior when the ash content was lower 5∼10%, and the iodine value was about 1,000 mg/g, the adsorption capacity decreased rapidly when ash content was over 15%. The manufactured activated carbon were found characteristics such as the iodine value was over 1,031 mg/g, the specific surface area was over 1,032 m2/g and the hardness was over 95% under manufacturing conditions which were carbonizated temperature of 600∘C(180 minute), activated temperature of 950∘C(210 minute) and steam weight of 6 mℓ/min.100 g coal.
