METHOD FOR REMOVING IMPURITIES FROM HYDROCARBON OILS

摘要

A method for removing impurities from a feedstock comprising a hydrocarbon oil is provided. The method comprises contacting the feedstock with an oxygen-containing gas under conditions effective to oxidize at least a portion of the impurities, as well as contacting the feedstock with a Lewis acid under conditions effective so that any Lewis base impurity(ies) in the feedstock can react with the Lewis acid. Any impurities so oxidized and/or reacted are then removed.
