利用NOx可被负载NH3的活性焦吸附催化剂转变为N2的机理,研究了活性焦低温脱除烧结烟气中的NOx.本试验烟气采用模拟烧结烟气,并探讨了烟气流量、反应温度,活性焦量和反应时间对活性焦吸附催化NOx性能的影响.试验结果表明,当流量从50ml/min提高到200ml/min时,活性焦对于NOx的脱除率逐渐降低,说明流量越大,NOx的去除率越低；试验反应温度从100℃上升到200℃时,NOx的脱除率在反应达到稳定后几乎相等；而对于活性焦量的影响,活性焦量从60g增加至120g时,活性焦量为120g的时候的脱硝效果最好,但是其他不同活性焦量下的NOx脱除率在反应稳定后都几乎在90％以上.%According to the mechanism of NOx can be adsorbed and catalysed by loaded NH3 activated coke, studies on the removal of NOx from sintering flue gas at low temperature using actived coke was conducted. This experiment using simulated sintering flue gas probes into the flue gas flow rate, reaction temperature, the amount of activated coke and the reaction time which influence the adsorption catalytic of active coke. The experimental results show that,when the flow from 50mL/min to 200mL/min, the NOx removal rate decreased gradually, this indicates the more the flow,the low the NOx removal rate;When the experimental reaction temperature varied from to,the NO removal rate after stable was almost equal; And for the amount of activated coke quantity increasing from to, the a-mount of activated coke of 120g had the best denitrification effect. But the denitrification effect of other different a-mount of activated coke was all almost 90% when the reaction ibecame stable.
