Journal ArticleDOI
Molecular characterization of kerogens by mild selective chemical degradation : ruthenium tetroxide oxidation
TL;DR: In this paper, the authors used selective chemical degradation with ruthenium tetroxide (RuO4) for the characterization of two kerogen isolates (Messel and Kimmeridge Clay), two kerogen-rich shales (Green River and Maoming) and a coal, (Loy Yang) was undertaken using a mild, oxidative technique.
Journal ArticleDOI
Molecular characterisation of kerogen from the Kimmeridge clay formation by mild selective chemical degradation and solid state 13C-NMR
TL;DR: In this article, the average molecular structure was obtained from solid state dipolar dephased 13C-CP/MAS NMR, using a peak synthesis approach based on chemical shifts of standard compounds.
Journal ArticleDOI
Elucidation of the Alum Shale kerogen structure using a multi-disciplinary approach
TL;DR: The significance and validity of integrating data obtained from a variety of analytical techniques to understand, elucidate and model the complex chemical structure of the Alum Shale kerogen was reported in this paper.
Journal ArticleDOI
Ruthenium tetroxide oxidation of natural organic macromolecules : Messel kerogen
TL;DR: In this article, the authors performed molecular characterisation of Messel kerogen using selective chemical degradation with ruthenium tetroxide (RuO 4 ) and found that high co-oxidant/substrate ratios yield high percentage of organic solvent extract and an increase in temperature liberates more products from the lower c/s ratio reaction mixtures more rapidly.
Journal ArticleDOI
Differentiation of German tertiary brown coal lithotypes ( amorphous and woody kerogens) using ruthenium tetroxide oxidation and pyrolysis-g.c.-m.s.
TL;DR: In this article, two physically separated, co-existing lithotypes of German brown coal (a structured woody and anamorphous) were subjected to ruthenium tetroxide (RuO 4 ) oxidation and pyrolysis-g.c.-m.s.
