原位升温拉曼光谱研究煤和焦炭的结构

Research of Structure of Coal and Coke by In-situ High Temperature Raman Spectra

对煤样品和焦炭样品分别用355 nm激光拉曼光谱仪进行原位升温拉曼光谱测试,将煤和焦炭样品分别升温至1 473 K进行研究。通过谱图解析研究和分析了煤和焦炭原位升温热解过程中其内部结构的变化。

The 355 nm laser Raman spectroscopic was used to measure the coal sample and the coke sample. Coal and coke samples were heating to 1 473 K by in-situ high temperature Raman spectra. The changes of the internal structure of the coal and coke by in-situ high temperature Raman spectra were studied by spectral analysis.
