| 摘 要： | 在石灰焙烧回转窑中加入燃料燃烧后产生的高温使石灰石分解生成生石灰和CO2气体．在此过程中，伴随着生成一些氮氧化物(NOx)．其中，主要是NO和NO2．这些气体排放到空气中，将对大气造成严重污染，同时也不利于CO2在饮料工业中的综合利用．因此，各国科学家都在研究NOx的去除方法．

| Abstract: | A new process was proposed for removing the nitrogen oxides(NOx) from the CO2 waste gases from the lime torrefied ratary furnace in Shanghai Baoshan Steel and Iron Company by means of absorption method of aqueous urea solution in order to recover highly pure CO2 for producing high quality beverage. The result obtained shows that the concentration of nitrogen oxides can be decreased from 6.5×10-4 mol/L to below 2.0×10-6 mol/L, the removing rate was over 99%. In the experiment, we made NO coming from the reaction NO2 +H2O be all oxidized to NO2 by using a special oxidized method, which was the key step for removing nitrogen oxides. |
