摘要
利用FTIR光谱分析及光谱分峰程序,对几种中等变质程度的煤样的红外光谱进行分析,六类羟基在我们所研究的中等变质程度煤中均存在,但是对于同一煤来说,六类氢键不一定同时存在于煤结构中。因此得出中等变质程度煤中含有少量的自由羟基和环氢键,主要羟基类型是OH—,πOH—OH,OH—醚氧以及它们的变化规律:羟基-π氢键随O/C比的减小而增大,醚氢键则先增大而后减少,羟基之间相互作用形成的氢键则先减小,而后增大,进而成减小趋势。
Several kinds of middle maturate coal were studied by Fourier transform infrared spectroscopy (FTIR) and curve-fitting analysis . There are six hydrogen bonds in the coal structure ,but to one kind of the coal, not six hydrogen bonds all are in coal structure. Conclusion was drawn that main hydrogen bonds on coal structure are OH-π, OH-OH, OH-ether, their change rule is :with the reduce of O/C, OH-π increases, OH-ether increases at first,then reduces, and OH OH reduces.
