Earlier it was found that various oil-soluble phosphorous compounds were active for vanadium removal from different crude oils. The phosphorous compounds preferentially reacted with low molecular weight vanadium species in the resin fraction and therefore the highest rate of vanadium removal was observed when the asphaltene fraction was partially or completely removed. Phosphorous compounds promoted the rate of vanadium removal during hydroprocessing over alumina in a trickle bed reactor. Some metal phosphates were prepared and tested for demetallization activity. Several mixed metal phosphates, such as Cr-Zr, Ni-Zr, Cu-Zr, V-Co-Zr, Fe-Co-Zr, Ni-Co-Zr, etc., exhibited high activity for both vanadium and nickel removal. These catalysts were found to possess HDM activity and activity maintenance comparable to conventional hydrotreating catalysts available commercially. The vanadium removal selectivity of the mixed metal phosphates was similar to that of the commercial catalyst, but much lower than that observed earlier for oil soluble phosphorous compounds. Since the lack of high vanadium selectivity for the mixed metal phosphates could be due to their transition metal component, they investigated the hydroprocessing of heavy oils over aluminas impregnated with different inorganic phosphorous compounds.
