The Development of Catalysts for Selective Catalytic Reduction of NO_x in Flue Gas

Catalyst is the key to the selective catalytic reduction (SCR) of NOx, and its catalytic performance directly affects the removal effect of NOx. The SCR technology, principle of SCR for de-NOx in flue gas, the effect factors of process, the type of SCR catalyst and reaction characteristics are introduced. Low-temperature catalyst (Metal oxide catalysts) is reviewed in detail. And future developments are also expected.
