ABSTRACT:
High quality activated carbon is produced by charging a mixture of an organic material such as wood, anthracite coal, brown coal, coconut husk, and a material containing metal oxide, metal carbonate or metal hydroxide, such as iron ore and lime, into an internal heating rotary furnace, preferably, having an internal space with a length of 1 to 10 times the diameter thereof, through an end of the rotary furnace, blowing air or oxygen gas into the internal space through an opposite end thereof, burning the distilled gas from the organic material and carbon monoxide generated by the reaction of the organic material with the metal oxide, carbonate or hydroxide, and uniformly circulating the burnt gas in the internal space to maintain the internal space at the reduction temperature.
