Study Oil Shale With Solid-State¹³C NMR

Fundamental experimental analysis and research of oil shale has been studiedwell. However, the study of the genetic potential of oil shale is rare reported.Solid-state¹³C NMR spectra analysis is a kind of important method in study of thechemical structure of coal and kerogen of difficult soluble or insoluble organiccomplex.In this thesis, through combining experiment and theory, using the determinationof dry distillation experiment, advanced technology¹³C NMR, receiving therelationship between the genetic potential of oil shale and the potential carbon, andmake full use of the theoretical analysis, so as to verify the accuracy of experimentalresults. We can lay the experimental and theoretical basis to evaluate the geneticpotential of oil shale for the future.A series of solid¹³C NMR experiments for Gansu oil shale was conducted by theBRUKER AVANCE III400WB spectrometer analyzer. Applying cross-polarizationmagic angle spinning （CP/MAS） technology, while using the total sidebandsuppression （TOSS）, obtaining a high-resolution spectrogram. Analyzing therelationship between genetic potential and total organic carbon, aliphatic carbon,potential carbon, showing that the potential carbon is the primary factor indetermining the genetic potential. Comparing the data of dry distillation experimentand solid state¹³C NMR, finding the carbon that remove to oil of total organic carbonis related to potential carbon. By theoretical analysis, finding the analysis result isrelated to the carbon that remove to oil of total organic carbon in dry distillationexperiment. Through¹³C NMR, dry distillation experiment and theoretical analysis,Gansu oil shale genetic potential is researched well.
