| 摘 要： | 用高温沉降炉研究无烟煤煤粉在830℃、880℃和930℃时热解产物中HCN、NH3、N2O、NO及NO2的析出规律.结果表明,随着温度的增加,煤样中的氮析出HCN、NO、NO2、NOx和气相含氮化合物的转化率呈先减少后增加趋势；NH3的转化率先增加后减少,NOx前驱物的转化率逐渐增加,N2O的转化率逐渐减小.NOx前驱物是煤样热解的主要气相含氮产物.

| Abstract: | The releasing regularity of HCN, NH3, N2O, NO and NO2 in the pyrolysis products of pulverized anthracite at 830℃, 880℃ and 930℃ are studied with a high temperature sedimentation furnace. The result shows that with the increasing of temperature, HCN, NO, NO2 and NOx are separated out from the nitrogen of coal specimen and the trend of conversion rate of nitrogen-containing compounds of gas phase is decreased first and then increased. The conversion rate of NH3 is increased first and then decreased; the conversion rate of predecessor of NOx is increased gradually; the conversion rate of N2O is decreased gradually. The predecessor of NOx is the main nitrogen containing product of gas phase of coal specimen pyrolysis. |
