Denitration catalyst regeneration cyclic utilization method

The invention discloses a denitration catalyst regeneration cyclic utilization method. By using the method, the activity recovery of an inactivated denitration catalyst can be realized and the activity detection is performed on the denitration catalyst; the effective screening on unqualified and qualified catalysts is realized; the qualification rate of the finally obtained regenerated catalyst iseffectively ensured; the catalysis efficiency of the catalyst during the denitration catalysis for a next time is ensured; the regeneration cyclic utilization circulation efficiency of the whole denitration catalyst is improved. 本发明公开了种脱硝催化剂再生循环利用的方法，该方法实现了对失活脱硝催化剂的活性恢复并对其进行活性检测，实现了不合格与合格催化剂的有效筛选，有效确保了最终获得的再生催化剂的合格率，保证了其再进行脱硝催化时的催化效率，提高了整个脱硝催化剂再生循环利用的循环效率。
