    摘要： A high temperature denitration catalyst of a gas turbine single plant contains TiO2, at least one of WO3 and MoO3 and V2O5 of 0.5 wt % or less, preferably 0.2 wt % or less, or none of V2O5, and is optimized to be used in a temperature range up to a maximum 450 to 600° C. The used high temperature denitration catalyst is immersed into a V-containing water solution and dried and/or burned. An intermediate temperature denitration catalyst is produced containing a V2O5 component of 0.5 wt % or more, preferably 1.0 wt % or more, and is optimized for use in a temperature range of 250 to 450° C. This intermediate temperature denitration catalyst is re-used in a combined cycle plant after being modified or in other plants.
