摘要

为了解煤燃烧过程中氮元素迁移规律

选用吡啶作为煤中吡啶型氮元素有机形态的模型化合物

研究其在 5 5 0℃～ 10 2 0℃范围内的热解规律。结果表明 :吡啶杂环在 770℃时开始裂解 ;在 85 0℃时腈类物质生成量最大

而腈类物质是吡啶氮向氰化氢 (HCN)转化过程中的主要中间产物 ;在 95 0℃以后含氮产物几乎全部以HCN的形式存在。HCN是NOx 生成过程中的主要中间产物。

Abstract

In order to understand the migration regularity of nitrogen element in the course of coal combustion

pyridine has been selected as model compound in organic form of pyridine type nitrogen element in coal to study the pyrolysis regularity of nitrogen in 550 ℃～1020 ℃ temperature range. The results show that the pyridine heterocyclic ring comes into splitting decomposition at 770 ℃; the nitrile matters produced being max. at 830 ℃

the nitrile matters being the main intermediate products in the conversion course from pyridine nitrogen to HCN; and nitrogen contened products are all existing in the form of HCN

which being the main intermediate products in the course of producing NO
