Vanadium and nickel removal from petroleum utilizing organic peroxyacid

Patent ·
OSTI ID:5997862
Vanadium and nickel levels in petroleum feeds are decreased by oxidation of the feed prior to the usual processing or upgrading steps. An organic peroxy-acid 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.
