Abstract (en)
[origin: WO2009003697A2] The present invention relates to a process for reactivating a catalyst which comprises a zeolite doped with an iron species, which comprises the step of treating the catalyst with hydrogen chloride-containing gas. The invention further relates to a reactivated catalyst which is obtained with the aid of the process according to the invention and to the use thereof for treatment of offgases from incineration processes, especially for the treatment of offgases from refuse incineration plants, very particularly for the reduction of nitrogen oxides.
