Abstract

Compounds occluded by asphaltenes of methanonaphthenic oil from the Krapivinskoye field and naphthenoaromatic oil from the Usinskoye field are investigated using the hydrogen peroxide-acetic acid system. The study has found that their composition contains normal and branched alkanes, n- alkylcyclohexanes, n-alk-1-enes, steranes, terpanes and n-alkanoic acids which are similar in structure. The presence of alkyl- substituted benzenes and alkylnaphthalenes in the composition of captured compounds is a distinguishing feature of naphthenoaromatic oil asphaltenes
