With the promulgation of the emission standard of atmospheric pollutants of thermal power plants (GB13223-2011), the emission requirement of nitrogen oxides (N0x) generated by coal burning in China is stricter. For the flue gas denitration technology, a Selective Catalytic Reduction (SCR) method is widely applied at present, the denitration efficiency of the SCR process is high and can reach more than 85%, wherein the catalyst is the main equipment of the SCR system, and the composition, structure, service life and related parameters of the catalyst directly influence the denitration efficiency of the SCR system. The initial investment cost of the catalyst accounts for about 40% of the whole denitration project, the SCR denitration system generally operates for about 3 years, and the catalyst needs to be replaced due to the reduction of the activity of the catalyst. The activity of the catalyst can be restored to more than 90% of the original activity by the regeneration method, and the cost is only 40-50% of that of the new catalyst. Therefore, the development of the regeneration of the catalyst has important significance for the popularization and the application of the SCR process.
