ABSTRACT:
A method for treating crude or residual fuel oil includes extracting vanadium from the fuel oil by contacting the fuel oil with an adsorbent and a solvent. The adsorbent may be modified with a compound having both acidic functionality and basic functionality. The method provides effective removal of vanadium from crude or residual fuel oil at moderate temperatures.
