TL;DR: A combination of solid-state 13C NMR, X-ray photoelectron spectroscopy (XPS) and sulfur Xray absorption near edge structure (S-XANES) techniques are used to characterize organic oxygen, nitrogen, and sulfur species and carbon chemical/structural features in kerogens as discussed by the authors.
Journal ArticleDOI
Quantification of nitrogen forms in Argonne Premium coals
TL;DR: In this article, X-ray photoelectron spectroscopy (XPS) was used to identify and quantify the organically bound nitrogen forms present in fresh Argonne Premium coals.
Journal ArticleDOI
Direct determination and quantification of sulphur forms in heavy petroleum and coals: 1. The X-ray photoelectron spectroscopy (XPS) approach
TL;DR: X-ray photoelectron spectroscopy (XPS) was applied to the problem of speciating and quantifying organically bound forms of sulphur in nonvolatile and solid hydrocarbons as mentioned in this paper.
Journal ArticleDOI
Sulfur K-edge x-ray absorption spectroscopy of petroleum asphaltenes and model compounds
TL;DR: In this article, the utility of sulfur K-edge X-ray absorption spectroscopy for the determination and quantification of sulfur forms in petroleum asphaltenes has been investigated and the results represent the first demonstration that nonvolatile sulfur forms can be distinguished and approximately quantified by direct measurement.

Slurry hydroprocessing for heavy oil upgrading using supported slurry catalysts
Zhiguo Hou,Bearden Roby,Kenneth Riley,Craig Sabottke,David T. Ferrughelli,Martin L. Gorbaty,William Olmstead +6 more
TL;DR: In this paper, a slurry hydroprocessing process (SHP) where a hydrocarbon feedstock is treated at slurry hydrotreating conditions, in the presence of a supported metallic catalyst which is a supported sulfide of a metal selected from the group of non-noble Group VIII metals, Group VIB metals and mixtures thereof where the support is an inorganic oxide and where the catalyst has an average diameter of about 0.5 to about 100 microns, is described.
