油页岩的拉曼光谱
|
摘要
采用拉曼显微镜-拉曼光谱仪结合光学显微镜对油页岩进行表征,利用基线校正消除背景效应得到清晰的拉曼光谱,观测到位于1 360cm~(-1)处的D峰和位于1 600cm~(-1)处的G峰.实验结果表明:窑街和桦甸油页岩的G峰都较强,证明油页岩中的干酪根已经很好地石墨化,成熟度较高.
Oil shale was characterized by micro Raman spectroscopy and optical microscope.Clear Raman spectra were obtained by eliminating background effects with baseline correction.The D Peak at 1 360 cm~(-1) and the G peak at 1 600 cm~(-1) were observed.The results showed that the G peaks of oil shale from Yaojie and Huadian were strong,which proved that the kerogen in the oil shale has been well graphitized with high maturity.
