Abstract:

There is currently interest in the chemical characterization of kerogens, primarily for better understanding of the origin, chemical history, and classifications of these materials. Recently developed methods for obtaining high-resolution 13C and 1H NMR spectra of solids have been exploited in structural characterization of kerogens. In particular, 13C CP/MAS spectroscopy has been extensively used in coal and kerogen studies to determine the aromatic/alkenic (or sp 2-hybridized) fraction (f a ) of total carbon that comprises aromatic/alkenic structures. Such calculations are based on the integrated intensities of the aromatic/alkenic and aliphatic envelopes of 13C NMR spectra.
