摘要: 对6种煤进行分级萃取, 按PBM法与NIST谱库化合物质谱数据进行计算机检索对照, 根据置信度或相似度, 并辅之以GC/FTIR数据确定化合物的结构. 检测出多种生物标志物,揭示了煤分子结构的复杂性, 实验结果表明, 随着煤化作用加深, 煤样中缩合程度加大.

关键词: 煤液化, 煤结构, 芳烃

Abstract: The present paper deals with the extracts from six raw coals and they were indexed according to the NIST database by PBM method, then their molecular configurations were confirmed via GC/FTIR. Many biomakers have been found in the extracts, which suggests that the configuration of coal molecules are very complicated; the compress degree of the coal increases along with the coalization.

Key words: coal liquefaction, configuration of coal molecule, aromatics
