Activated carbons were prepared from Youngwall coal by steam activation in this study. The feasibility of the Youngwall coal to commercial activated carbon was examined. The variation of pore structures and the development of porosity in activated carbons were investigated by changing activation conditions in batch type apparatus. The values of BET surface area and adsorption capacity of iodine and methylene blue of the resulting activated carbons were obtained as high as 1,000㎡/g, 900㎎/g, 150㎖/g, respectively. Youngwall activated carbon prepared in this study showed much higher pore volume in pore diameter over l0Å than that of commercial reference activated carbon(Ningxia Taihua ZJ-15C) produced from China anthracite.
