| 摘 要： | 在热重分析仪(TGA)上进行了O(2)/CO(2)及O(2) /Ar气氛下煤焦的燃烧实验,同时利用傅立叶变换红外光谱仪(FTIR)对燃烧产物进行实时检测.结果表明,在焦炭颗粒的燃烧过程中焦炭氮会转化为HCN、HNCO、N(2)0等.与O(2)/Ar气氛下的燃烧相比,0(2) /CO(2)气氛煤焦燃烧焦炭氮的转化时间延长...

| Abstract: | The conversion of char nitrogen in O2/CO2 and O2/Ar mixtures was studied by thermogravimetric analyzer(TGA) together with Fourier transform infrared(FTIR) spectroscopy.The results show that char-N can be released as HCN,HNCO,N2O.Comparing the conversion behaviors in O2/Ar,the time scale of char-nitrogen conversion in O2/CO2 is longer and the distribution of N-containing gases is different.As the combustion temperature increases,the time scale of char-nitrogen conversion become shorter and the fraction of N2... |
