The resu lts demonstrated that after oxidation, the aromatics content w as decreased, the resins content w as increased, the satu- rates content and the asphaltents contentw ere unchanged, the ratio of light composition to heavy compo- sition in the alkane w as increased, and the viscosity of crude oilw as increased.
