摘　　要：对FCC废弃物在不同温度下(400～800℃)催化NH3还原NO的活性进行了试验研究;系统考察了700℃时反应气体中各种组分NH3、NO、O2和SO2浓度对FCC废弃物脱硝的影响;研究了700～850℃范围内反应气体中添加CH4对FCC废弃物脱硝的改进效果。NO reduction by NH3 over FCC spent catalyst in the temperature range of 400-800℃ were studied, and the effects of NHa, NO, O2 and SO2 in gas composition on NO reduction were investigated in a series of experiments. In the range of 700-850℃, NO reduction by adding CH4 composition was improved.
