Experimental Research on NO Removal for Fixed Bed Reactor and Fluidized Bed Reactor at Low Temperature

Abstract

Abstract. The method of the selective catalytic reduction (SCR) has become one of the most effective applications of NO x removal technology. Most studies focus the side on fixed bed denitrification at low temperature low space velocity experimental condition, while few studies about denitrification at low temperature high space velocity experimental condition. The catalyst, Mn-Ce/AC, has been prepared by impregnation method in this paper. Under the experimental condition of low temperature high space velocity, catalytic activity was researched in fixed bed denitrification reactor and fluidized bed denitrification reactor respectively. Results show that, the catalytic NO removal is 10.5% at 180℃, the space velocity is 100000 -1 , in fixed bed denitrification reactor; while it is 81.3% in fluidized bed denitrification reactor.
