Introduksion tan Saray Factors na Selective Catalytic Reduction (SCR) Catalysts

Saray selective catalytic reduction (SCR) catalysts et manguusar na reducing agent pian makapili na NOx ed flue gas, ya mamawala na non-makasamal tan anggapoy polusyon-free ya N2 tan H2O, diad kiwas na sakey a catalyst.

Say temperatura na reaksion so mandetermina ed aglabat say kapeles na reaksion na saray reactant noagta ontan met ed inka-reaktibo na SCR catalyst. Diad inkalapagan, say mas atagey a temperatura na reaksion so manresulta ed mas maples a reaksion tan mas atagey ya aktibidad na katalista, a manresulta ed mas melag a espasyo na reaksion tan karakel na reaktor kada yunit na lawak. No ikonsidera so pampainit na reactant, panangontrol na sistema, tan say matukoy ya temperatura na catalyst, say temperatura na sistema na SCR et kaslakan ya walad baetan na 320 anggad 420 degree.

Say kapeles na liwang et manunan paraan na desinyo parad saray selective catalytic reduction (SCR) catalysts. Susukat toy panaon na pansiansia na flue gas (basa ya flue gas ed silong na estandarten kondisyon) ed loob na catalyst volume, tan diad pigaran laknab et nadetermina no kasin sigpot ya onkiwas iray reactant. Impluensyaan to met so panag-scour na reactor catalyst framework tan say friction loss na flue gas.

Say kalidad na flue gas flow pattern so mandetermina ed inkaepektibo na catalyst. Say matukoy ya paraan na iyaagus na flue gas et aglabat mamalaknab ed pangusar na catalyst noagta mamawas met ed friction loss. Diad desinyo na inhinyeriya, say flue gas flow field et kaukolan ya maalwar ya ikonsidera. Saray ammonia injection points et nepeg ya walaan na magulon kondisyon pian nadampot so sankaabigan ya panlalaok ed flue gas tan makaporma na malinew ya homogenous flow region.
