不同预处理方式和模拟产气实验对煤结构的影响

采用傅里叶红外（FTIR）及x-射线衍射（XRD）对反应前后煤体的结构进行检测，结果表明：原煤样经酸氧化、白腐真菌降解以及随后的模拟产气实验后，芳香环逐步被打开，芳香层片间距增大，芳香层数减少，碳碳键断裂处引入了羟基等官能团；煤样的大分子结构被降解，芳香结合程度降低。这表明所选取茵群可以有效降解低变质程度煤。...

Summary:采用傅里叶红外（FTIR）及x-射线衍射（XRD）对反应前后煤体的结构进行检测，结果表明：原煤样经酸氧化、白腐真菌降解以及随后的模拟产气实验后，芳香环逐步被打开，芳香层片间距增大，芳香层数减少，碳碳键断裂处引入了羟基等官能团；煤样的大分子结构被降解，芳香结合程度降低。这表明所选取茵群可以有效降解低变质程度煤。

Coal structure of pre and post reaction was detected by FTIR and XRD. Experiment results show that its aro- matic ring is gradually opened, distance between aromatic plane largen, the number of aromatic plane decreases through acid oxidation, white rot fungus degradation and the subsequent biogenic methane production simula- tion, carbon-carbon bond has been broken and functional groups is added into the structure such as hydroxy etc. Mac- romolecular structure of the coal sample is degradated and the aromatic combination is reduced. All these show the se- lected bacterium can degrade low-rank coal effectively.
