    摘要: The present invention provides for a method of decreasing the metals content of metal containing petroleum streams by forming a mixture of the petroleum fraction containing those metals and an essentially aqueous electrolysis medium, and passing an electric current through the mixture at a voltage, pH and time sufficient to remove the metals such as Ni, V and Fe from the stream (i.e. to produce a petroleum fraction having decreased content of the metals). The cathodic voltage is from 0 V to -3.0 V vs. SCE at a pH of from 6 to 14, preferably 7 to 14, most preferably above 7 to 14.The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their Ni and V content.
