    摘要: The invention relates to a process for demetallating a petroleum stream by contacting a metals-containing petroleum feed in the presence of a base selected from Group IA and IIA hydroxides and carbonates and ammonium hydroxide and carbonates and mixtures thereof an oxygen containing gas and a phase transfer agent at a temperature of up to 180.degree. C. for a time sufficient to produce a treated petroleum feed having a decreased metals content. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their metals, e.g., Ni and V content.

    摘要: The present invention provides for a method for decreasing the Conradson carbon content of petroleum streams by forming a mixture of the petroleum stream and an essentially aqueous electrolysis medium, and passing an electric current through the mixture at an anodic voltage and pH sufficient to produce a petroleum fraction having decreased Conradson carbon content. The anodic voltage is from +0.5 to +1.5V vs. SCE. Preferably the pH is acidic. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries.

    摘要: The invention is a method for demetallating petroleum streams by subjecting a hydrocarbon soluble metals-containing petroleum stream and an aqueous electrolysis medium to a sufficient anodic potential at a pH sufficient to produce a treated petroleum stream having a decreased metals content. The invention is useful for enhancing the value of petroleum streams that traditionally have limited use in refineries due to their content of metals, particularly Ni and V.
