    摘要： 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.

    摘要： Processes described include reacting a fresh or spent catalyst, or sorbent, with a solution containing an extracting agent (such as an acid or a base). Preferably, the catalyst contains both alumina and a molecular sieve (or a sorbent), and the reaction is performed under relatively mild conditions such that the majority of the base material does not dissolve into the solution. Thus, the catalyst can be re-used, and in certain instances the catalyst performance even improves, with or without re-incorporating certain of the metals back into the catalyst. Additionally, metals contained in the catalyst, such as Na, Mg, Al, P, S, Cl, K, Ca, V, Fe, Ni, Cu, Zn, Sr, Zn Sb, Ba, La, Ce, Pr, Nd, Pb, or their equivalent oxides, can be removed from the catalyst. Some of the metals that are removed are relatively valuable (such as the rare earth elements of La, Ce, Pr and Nd).
