摘 要:本文探计预热对神木镜煤和柳林镜煤结构和喹啉抽提率的影响。用热台显微镜考察抽提物的碳化特性。左320~460℃预热温度区间里,预热柳林镜煤的抽提率呈现出两个温度间隔60℃的极大值,一个在其热分解开始附近,一个在软化点附近。而预热神木镜煤仅在开始热分解温度附近出现一个抽提率极大值。用DTA及FTIR分析数据可对上述喹啉进行合理解释。The effect of preheating on structure and extraction yield of quinoline of shenmu vitrain and Liulin vitrinite is investigated, The carbonizing properties of quinoline extracts is inspected by means of hot-stage microscopy During preheating temperatures between 320 and 460℃, the extraction yield of quinoline of Liulin vitrinite has two maxim urns at interval of 60℃, one maximum point appears at temperature nearby its starting thermal decomposition, the another at preheating temperature nearby the plastic soften point That of Shenmu vitrain has only one maximum at prehating temperature nearby its starting thermal decomposition, These results are explained by both-DTA and FTIR analysis data
