<P>PROBLEM TO BE SOLVED: To provide a halogen-containing compound degrading agent capable of degrading a halogen-containing compound at a remarkably lowered temperature as compared with that before in dry treatment without using water. <P>SOLUTION: The halogen-containing compound degrading agent contains a solid alkaline agent to which at least one of oxide type catalysts and mineral type catalysts showing solid acidity. The solid alkaline agent is preferably at least one compound selected from among oxides, hydroxides, and carbonates of alkali metals and alkaline earth metals. The oxide type catalysts are preferably at least one compound selected from among metal oxides showing solid acidity (that is, SiO<SB>2</SB>, TiO<SB>2</SB>, Al<SB>2</SB>O<SB>3</SB>, ZrO<SB>2</SB>, La<SB>2</SB>O<SB>3</SB>, Y<SB>2</SB>O<SB>3</SB>, Cr<SB>2</SB>O<SB>3</SB>, ZnO, Sn<SB>2</SB>O<SB>3</SB>, V<SB>2</SB>O<SB>5</SB>, and WO<SB>3</SB>). Further, it is also preferable to select at least one compound from zeolite type minerals and clay type minerals showing solid acidity. <P>COPYRIGHT: (C)2009,JPO&INPIT |
