<P>PROBLEM TO BE SOLVED: To provide a method for producing refined activated carbon low in sulfur content by removing a sulfur content contained in activated carbon (A) containing the sulfur content. <P>SOLUTION: The sulfur content contained in the activated carbon (A) is removed by bringing the activated carbon (A) containing the sulfur content into contact with hydrogen chloride gas (B). For example, an activated carbon filling container (2) is filled with the activated carbon (A), which is brought into contact with the hydrogen chloride gas (B) at a space velocity of 1/h-2,000/h by blowing the gas (B) in the activated carbon filling container (2). An apparatus (1) for removing the sulfur content is used. The apparatus is provided with the activated carbon filling container (2), a gas introducing pipe (3), and a gas discharging pipe (4). The hydrogen chloride gas (B) is introduced through the gas introducing pipe (3) and discharged out of the container through the gas discharging pipe (4) so that the gas (B) is brought into contact with the activated carbon (A). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
