ABSTRACT:
Vanadium and nickel levels in petroleum feeds are decreased by oxidation of the feed prior to the usual processing or upgrading steps. An organic peroxyacid is used in the oxidation. The reduction in vanadium and nickel levels results in increased lifetime of catalysts used in subsequent processing steps such as in hydrodesulfurization or catalytic cracking.
