velocity in catalyst pores The flow rate in the catalyst pores refers to the flow rate of flue gas in the catalyst pores, which is different from the flow rate in the reactor. Different catalyst and flue gas conditions have different requirements for the flow rate in the catalyst holes. Typical values are as shown in the table below: Serial number Flow rate m/s Catalyst type 1 6-7 Medium temperature catalyst 2 5-6 Low Temperature Catalyst 3 Ultra-low temperature catalyst 4 2-5 High temperature catalyst Serial number Flow velocity m/s Dust content g 1 6-7 10-50 2 5-6 1-10 3 4-5 4 2-4 0-0.1 A high flue gas flow rate helps reduce the clogging and adhesion of smoke dust, but it will reduce the denitrification efficiency of the catalyst. A low flue gas flow rate helps improve the denitrification efficiency, but it will increase the clogging and adhesion of smoke dust. Therefore, according to the flue gas conditions and site conditions, select the appropriate flue gas flow rate. #scrcatalyst #catalyst
