<P>PROBLEM TO BE SOLVED: To provide a denitration catalyst for high-temperature exhaust gas, which can keep the denitration performance at high temperature of ≥500°C over long time, and to provide a method for producing the denitration catalyst for high-temperature exhaust gas, and a method for denitrating high-temperature exhaust gas. <P>SOLUTION: The denitration catalyst for high-temperature exhaust gas is used for denitration catalyst for nitrogen oxide-containing high-temperature exhaust gas and obtained by carrying tungsten oxide (WO<SB POS="POST">3</SB>) on a compound oxide carrier containing titanium oxide so that the number of the tungsten oxide molecular layers is ≤5. Even when continuing high-temperature denitration, the bonding force of WO<SB POS="POST">3</SB>to the carrier can be kept properly and volatilization can be suppressed while keeping high denitration performance. For example, the denitration catalyst is particularly suitable when nitrogen oxides contained in the high-temperature gas discharged from a thermal power plant, a high-temperature boiler or the like are reduced and removed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
