ABSTRACT:
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.
