TL;DR: Ru ion catalyzed oxidation (RICO) has been used to probe the structural details of asphaltene molecules from Athabasca bitumen, and the ability of RICO to remove nearly quantitatively aromatic carbons while leaving aliphatic and naphthenic structures essentially unaffected has been exploited for the quantitative determination of the following structural features.

TL;DR: In this article, a method is described for the isolation of sulfides from petroleums based on the selective oxidation of sulfide to more polar sulfoxides which are easily removed from the mixture and their subsequent reduction to sulfides.

TL;DR: In this paper, the oxygen distribution in the Athabasca asphaltene has been investigated and it was shown that 75% of the oxygen is present in the form of hydroxyl groups.

TL;DR: In this article, a vitrinite concentrate of Balmer 10, medium-volatile bituminous coal (433), and highvolatile Moss 3 coal (535) were oxidized in air at 85°C for four days to partially destroy the swelling characteristics as measured by the Ruhr dilatometer.

TL;DR: In this paper, the absorption, excitation and emission spectra of Athabasca (Alberta, Canada) asphaltene and five of its fractions separated according to molecular weight (MW) by gel permeation chromatography (g.p.c.) on Bio-Beads SX-1.
