This invention relates to an in-situ remanufacturing method of SCR aged catalyst. More specifically, in case the activity of the catalyst, which is used in selective catalytic reduction (SCR) to remove nitrogen oxides, is decreased, such deactivated catalyst, in this in-situ remanufacturing method, is not to be separated from its related reactor but to be remanufactured in-situ for elimination in this method, which, compared to the one that otherwise includes detachment and transportation to remanufacturing facilities, should prevent potential damage to the catalyst, reduce transportation costs as well as additional enormous costs depending upon unloading and loading of the catalyst and shorten the remanufacturing time. The activity of reclaimed catalyst in this invention is recovered at a level of 95% or more than that of fresh SCR catalyst by rapidly facilitating the in-situ elimination of any contaminant and possesses high economic efficiency as there is no catalyst loss during the process. The reuse of the catalyst which otherwise is to be disposed is also possible, mitigating environmental burden.

The present invention relates to a method for the remanufacture in situ of a commercial denitration SCR catalyst. More particularly, the present invention relates to a method for the remanufacture in situ of a denitration SCR catalyst, in which the method remanufactures the waste catalyst in situ without separating the waste catalyst from a reaction device when the activity of the catalyst used in a selective catalytic reduction (SCR) for removing nitrogen oxide is degraded.

The contaminant of the catalyst remanufactured by the method of the present invention can be quickly and easily removed in situ, and therefore, the performance of the catalyst remanufactured by the method of the present invention is recovered by 95% or higher of the performance of a new catalyst and reused. Furthermore, a catalyst loss is prevented during a remanufacturing process, thus achieving economic advantages, and the method of the present invention enables reuse of the waste catalyst to be discarded or buried to thus reduce environmental contamination.
