Composition of petroleum asphaltenes derived from ruthenium-catalyzed oxidation

[Display omitted] Ruthenium ion-catalyzed oxidation of methanonaphthene oil (Krapivinskoye oilfield) revealed that its high molecular asphaltenes contain aromatic–aliphatic bridges and non- covalently bound (occluded) compounds.

Summary:[Display omitted] Ruthenium ion-catalyzed oxidation of methanonaphthene oil (Krapivinskoye oilfield) revealed that its high molecular asphaltenes contain aromatic–aliphatic bridges and non- covalently bound (occluded) compounds. Covalently bound fragments are represented by C5–C18n-alkanes, aromatic biphenyl-type structures, and naphthalenes located in the peripheral part of asphaltene molecules. Typical biological markers, i.e. terpanes, steranes, and n-alkanes have been identified among the occluded compounds.
