A novel process for metal content reduction of hydrocarbon oil is disclosed, which is primarily aimed at reduction of vanadium and nickel. The process uses electricity to accelerate the demetallation process, but only the flow of electrons of the electric current is used to expedite the reaction, instead of the electrolysis effect of the electric current. The process is carried out by adding inter-phase surface active reagent and phase transfer catalyst at a relatively low temperature range of 80 to 200&#xb0; C. and achieves metal content reduction for vanadium and nickel. Aqueous phase alcoholic derivatives of amine solution is treated with hydrogen sulfide, carbon dioxide, etc. by additive reaction to render it more suitable for carrying more electric current and make them more active for metal reduction.

Process for metal reduction of hydrocarbon oil

The invention describes process for demetallation of vegetable oils and animal fats to reduce metal content below 1 ppm to make them suitable for hydroprocessing feedstocks. The process comprises acid treatment with very low concentration of acids, utilizing synergistic effect of phosphoric acid and citric acid, followed by counter-current treatment with clay without intermediate step of water washing and treatment with ion exchange resin.
