煤炭解耦燃烧过程n迁移与转化ⅰ:热解阶段煤n的释放规律
, PP. 919-926
Keywords: 煤,解耦燃烧,热解,nh3,hcn
Abstract:
？在固定床装置上进行了三种煤的热解实验,考察了热解温度、热解时间等因素对煤氮迁移转化的影响。热解实验表明,a煤1073k热解产生hcn,在热解前3min释放完毕,早于nh3释放,且当nh3开始逸出后hcn生成量急剧减少;三种煤热解hcn、nh3的累积释放量在不同时刻达到各自最大值后急剧下降;半焦氮随热解温度的升高而增加。在973~1123k三种煤热解有50%~60%煤氮转化为焦氮,40%~50%煤氮随挥发分一起释放,挥发分氮有20%~50%的氮物种以nh3和hcn的形式存在,其中,hcn占气相氮的50%~60%、nh3占40%~50%。
