Experimental Study on Low Temperature Denitrification of Fe2O3/LAC
Coal based activated coke with different contents of Fe2O3(mass fractions of 4％,6％,8％,and 10％)was taken as the research object.The impregnation method was used to shape the loaded modified coal based activated coke into columns,and the denitrification efficiency of Fe2O3/LAC(Lignite Activated Coke)under different loading amounts was investigated.The experimental results show that when w(Fe)=8％,the highest denitrification efficiency of Fe2O3/LAC can reach 77.5％,and the desulfurization efficiency in water and sulfur resistance remains at 60％～90％.After introducing H20,the denitrification efficiency drops to a minimum of 51.2％,and when H2O supply is stopped,it returns to 56％.The adsorption and desorption curves of activated coke are all Type Ⅰ adsorption curves with H4 hysteresis loops,containing mainly Fe2O3 oxides and a small amount of TiO2 and MnO.
