| 摘 要： | 为了实现煤的洁净转化,研究煤热解过程中N转移的机理,实验在固定床反应器上采用程序升温法对云南煤在不同温度下进行了氩、甲烷、15%水蒸气/氩和15%水蒸气/甲烷气氛下的煤加氢热解研究,主要对热解过程中产生的No2主要前驱物NH3和HCN的释放规律进行了考察,实验表明云南煤热解释放的NH3随热解温度的升高而增加,但是HCN...

| Abstract: | This paper mainly discusses the formation and release of NOx precursors—NH3 and HCN during coal fixed-bed pyrolysis.Yunnan coal was selected in our experiments.The reaction gases were Ar,CH4,15%H2O/Ar and 15%H2O/CH4.The results indicate that the NH3 yield increases with the temperature increasing;but the HCN yield hardly increases with the temperature increasing.The steam promote the release of NH3 and HCN,but it is on the contrary when it is methane. |
