A method for economically modifying a gas turbine single plant into a combined cycle plant, a method for re-using a used high temperature denitration catalyst of the gas turbine single plant as an intermediate temperature denitration catalyst of other modified, existing or new plants and a re-produced catalyst are provided. The high temperature denitration catalyst of the 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 the temperature range up to maximum 450 to 600°C. The used high temperature denitration catalyst is immersed into V-containing water solution and dried and/or burned. An intermediate temperature denitration catalyst is re-produced containing V2O5 component of 0.5 wt% or more, preferably 1.0 wt% or more, and being optimized to be used in the temperature range of 250 to 450°C. This intermediate temperature denitration catalyst is re-used in the combined cycle plant after modified or other plants.
