废旧脱硝催化剂再生清洗研究

Cleaning regeneration research of used denitration catalyst

脱硝催化剂经电厂使用后各方面性能下降较多,使用硝酸、硫酸、EDTA等一系列配方对其进行再生清洗,废旧脱硝催化剂的各方面性能得到了一定程度的恢复。

All aspects of performance of denitration catalyst had dropped a lot after using by the power plant.The regeneration cleaning by applying HNO3,H2SO4,EDTA and so on had been done,and it got that all aspects of performance of denitration catalyst had recovered to a certain extent.
