Effect of microwave radiation on pore structure of SCR denitration catalyst

Based on the background of SCR denitrification technology widely used in pulverized coal utility boilers, the characteristics of denitrification catalysts used in industry were studied. Microwave radiation was used to prepare 8Mn-8Fe/Al2O3 denitrification catalyst by using microwave as an efficient...

Description
Summary:Based on the background of SCR denitrification technology widely used in pulverized coal utility boilers, the characteristics of denitrification catalysts used in industry were studied. Microwave radiation was used to prepare 8Mn-8Fe/Al2O3 denitrification catalyst by using microwave as an efficient and fast heating method. The results show that microwave irradiation can make the catalyst heated from inside to outside without temperature gradient, make the molecule oscillate rapidly, change the specific surface area and pore structure of the catalyst, thus improving the catalytic activity of the catalyst.
