| 摘 要： | 采用元素分析、红外光谱、XRD及扫描电镜等分析手段对煤焦油QI进行了组成结构的定性分析.结果表明,煤焦油QI主要由焦粉、煤粉、热解碳和高温缩聚产物组成.煤焦油QI经氯化锌溶液浮选分离后,定量地确定了焦粉、煤粉、热解碳和高温缩聚产物在煤焦油中的含量.相关分析数据表明,无烟装煤技术7、.63 m焦炉本身的结构特点和加热制度是造成煤焦油中QI含量偏高的主要原因,其中因高温作用而产生的热解碳及高分子聚合物对QI的贡献占主导地位.

| Abstract: | The characters of QI in coal-tar are analyzed by ultimate analysis,FTIR,XRD and SEM etc,and it is showed that the QI is made up of coal powder,coke powder,pyrolytic carbon and condensation polymerization products.The content of each QI part in coal-tar is determined by floating QI in different density zinc chloride liquids.The related analysis data show that high QI in coal-tar is mainly caused by smokeless charging,the structural characters and heating system of 7.63 m coke oven,but the macromoleclar polym... |
