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 Raman spectra of coal and coke samples were respectively measured by in situ Raman spectroscopy using a 355 nm laser Raman spectrometer. The coal and coke samples were respectively heated to 1 473 K for study. The changes of the internal structure of coal and coke in pyrolysis process were investigated and analyzed by spectral analysis.
