Research progress of honeycomb denitrification catalyst regeneration technology

Coal combustion will produce a large amount of nitrogen oxides (NOx) and other atmospheric pollutants. As coal-burning pollution prevention and control requirements become more and more stringent, denitrification catalysts have been widely used, and a large number of deactivated denitrification catalysts are produced every year. The development of regeneration technology has attracted people's attention. The application of denitration catalysts was introduced, the reasons for the deactivation of honeycomb denitration catalysts were analyzed, the research progress of honeycomb denitration catalyst regeneration technology was reviewed, and the future honeycomb denitration catalyst regeneration technology was prospected.
