Abstract

The formation of HCN and NH 3 from fuel nitrogen during pyrolysis was studied in a prefilled reactor system with slow (temperature-programmed) heating and in a drop-in reactor system with a rapid heating rate. The experimental results indicate that the formation of HCN and NH 3 is obviously affected by coal properties. The effects of these coal properties vary with the heating fashion. Coal rank, characteristic of char residue, surface characteristics, and composition of the coal are important factors influencing the formation of HCN and NH 3 during pyrolysis.
煤性质对煤热解过程中HCN和NH3释放的影响
研究了燃料氮热解过程中HCN和nh3在慢速加热(程控温度)预充式和快速加热的滴注式反应器系统中的生成。实验结果表明,煤的性质对HCN和nh3的形成有明显的影响。这些煤的性质随加热方式的不同而变化。煤的煤阶、焦渣特性、煤的表面特征和煤的组成是影响热解过程中HCN和nh3生成的重要因素。
