NMR在固体化石能源中的应用

综述NMR在固体化石能源的科学与技术领域中的应用,各种固态NMR技术,诸如CP、MAS、DD、DNP、TOSS、CRAMPS、NMRI等,均已用于表征化石能源的化学结构,其中以芳碳率与芳氢率作为结构多数最为重要。最近发展中的新方法,例如魔角慢转以及不同结合质子碳的谱编辑技术,展示了从核磁谱取得更多结构信息的前景,NMR可用于研究固体化石能源自然或人工热演化的机理;油气资源潜力的评价;煤在化学加工中性质的预测等。

NMR APPLICATIONS TO THE SOLID FOSSIL ENERGIES

This review is concentrated on the NMR appucations to the science and technology of the solid fossil energies.Various solid state NMR techniques such as CP,MAS,DD,DNP,TOSS,CKAMPS,NMRI have been used for the characterization of chemical structure with different parameters in which the aromaticity of carbon and hydrogen is the essential.Recently,new developing techniques of the triple angle MAT and of the spectral editing based on proton multiplicities reveal that more detail structural information may be extracted from the NMR spectra.The topics of NMR application to the solid fossil energies are focused on the natural and artificial thermal evolution mechanism,the oil and gas potential evaluation and the coal property prediction during chemical processing.Sixty-five references have been cited in which twenty-seven are contributed by Chinese authors.
