<p><P>PROBLEM TO BE SOLVED: To provide a method for removing a sulfur component contained in a chlorine gas (1) without increasing moisture content. <P>SOLUTION: The removal method comprises removing the sulfur component by bringing the chlorine gas (1) containing the sulfur component into contact with a metal oxide (2). For example, the metal oxide to be used is a particulate consisting of an aluminum oxide, a titanium oxide or a silicon oxide with the BET specific surface area of 10 m<SP>2</SP>/g or more and the pore volume of 0.05 cm<SP>3</SP>/g or more for the pore sizes of 0.1μm or more to 1μm or less in radius. Thereby, a pure chlorine gas (1') which does not contain the sulfur component can be easily provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
