Pyrolysis/High Resolution Mass Spectrometry with Metastable Peak Monitoring Applied to the Analysis of Green River Shale Kerogen

Abstract

High resolution mass spectra of products resulting from the temperature programmed pyrolysis of Green River shale kerogen in the ion source of a mass spectrometer showed mass peaks to m/z 700. Elemental composition and linked metastable scans, particularly of components containing heteroatoms, were obtained at five second intervals during pyrolysis. This showed that nitrogen and oxygen containing compounds are present in greater abundance than those containing sulfur, and that sulfur always appears in combination with one of the other heteroatoms. Nitrogen is found primarily as a part of stable aromatic ring systems; quinoline and isoquinoline structures appear to be most probable. Oxygen containing species were associated principally with aliphatic hydrocarbon skeletons.
