摘要

以不同含量Fe2O3(质量分数为4％、6％、8％、10％)的煤基活性焦为研究对象,采用浸渍法将负载改性的煤基活性焦进行柱状成型,探究不同负载量下Fe2O3/LAC(Lignite Activated Coke)的脱硝效率.实验结果表明:w(Fe2O3)=8％时,Fe2O3/LAC脱硝效率最高可达77.5％,抗水抗硫中脱硫效率保持在60％～90％,通入H2O后脱硝效率最低降至51.2％,停止供H2O恢复至56％;活性焦吸附脱附曲线均为Ⅰ型吸附曲线H4滞后环,所含氧化物以Fe2O3为主,还有少量的TiO2和MnO.

Abstract

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.
