PERFORMANCE EVALUATION AND REGENERATION METHOD OF AGED DE-NOX CATALYSTS

摘要

The present invention provides a characterization of the catalyst and the NOx conversion reaction test equipment to characterize the waste removal catalyst If grinding is carried out to reproduce the catalyst performance evaluation process that can determine whether to play a catalyst recycle whether using a number of ways on the spent catalyst regeneration step of recovering at least 90% of the original performance of the catalyst. More specifically, the spent catalyst characterization instrument (ICP; Inductively Coupled Plazma Atomic Emission Spectrometer, XRD; X-ray Diffractometer, BET, Porosimeter, TGA; Thermogravimetric Analyzer), such as the use of the catalytic activity of factor analysis, and at the same time NOx conversion reaction The playback process performed an experiment carried out by way of the catalyst performance evaluation process and the spent catalyst to thermal and chemical regeneration processes to evaluate the performance of the catalyst on the basis of a result of recovering over 90% of the original performance of the main information.
