摘　　要：在流化床上进行了两种煤的热解及焦炭的燃烧实验，研究了煤种、粒径、热解条件对煤焦性质及Ｎ２Ｏ转化率的影响。研究结果表明：除粒径外，煤种和热解条件都对煤焦中Ｎ的Ｎ２Ｏ转化率有明显影响。The pyrolysis of two kinds of coal and coke combustion test has been conducted on a fluidized bed.Studied is the effect of coal type,particle diameter and pyrolysis conditions on coal char properties and N 2O conversion rate.The results of the study show that with the exception of the particle diameter both the coal type and pyrolysis conditions have a marked effect on N 2O conversion rate of N in the coal char.
