Abstract
|
Researchers
studied trends in the vanadium and nickel concentrations in asphaltenes of
heavy oils from various oilfields, in which the total content of these metals
vary from 0.0049 to 0.1795 wt %. Results revealed that as the vanadium and
nickel content in heavy oils increases, vanadium concentrates faster than
nickel in asphaltenes.
In heavy oils, asphaltenes contain approximately 40–90% of total vanadium and 25–75% of total nickel. The summed concentration of vanadium and nickel in heavy oil asphaltenes can reach 1 wt %. |
