摘要

对气流床水煤浆气化细灰和粉煤气化细灰及其原煤的热解特性与官能团特征进行研究

结合工业分析、元素分析、红外光谱(FTIR)方法以及热重-质谱联用(TG-MS)技术

分析了两种气化工艺所得细灰的特性

以及细灰与原煤官能团结构特征的差异。结果表明

气化细灰在经历煤气化过程后仍有部分挥发分未完全分解

细灰中的挥发分含量与其气化工艺有关;煤气化过程中

部分官能团未分解

并可能有部分官能团重排生成了较稳定的含氧化合物等新官能团。

Abstract

Raw coals as well as fine gasification ashes from pulverized coal gasifier and coal water slurry (CWS) gasifier were studied by proximate analysis

ultimate analysis

FTIR and TG-MS to determine the characteristics of structure and pyrolysis behavior of fine gasification ashes and raw coals with different coal gasification technologies. Some volatile matter remained in fine gasification ash after coal gasification

and the volatile matter content of ash was related to the gasification technology. During gasification

part of the functional groups kept undecomposed and rearrangement of molecular structures caused formation of some relatively stable functional groups

such as phenolic aldehyde

carbonate minerals and oxy-compound structures.
