Bituminous coal-based activated carbon was prepared in a rotary kiln type furnace and the effect of pretreatment on the preparation of activated carbon was investigated. A manufacturing process using steam as the activation agent was employed. The flow rate of the activation agent(steam) was found to have significant influence on the development of the porous network of the briquette type activated carbon. Furthermore, activation temperature affected on the properties of activated carbon. The adsorption capacity, or iodine value(I₂) was increased in the activation temperature range of 800 to 900℃, yet decreased at higher temperatures than 900℃. Then, the activation effect was analyzed by the definition of the activated carbon(AC) yield. It was found that the optimum activation time and steam amount were 240 minutes, and 1g steam/g coal·hr, respectively.
