Abstract
The present invention provides for a process for electrochemically decreasing the Conradson carbon number of petroleum streams by contacting a Conradson carbon containing petroleum stream and an aqueous electrolysis medium with a low hydrogen overpotential metal cathode at an electric current and pH sufficient to decrease the Conradson carbon of the petroleum stream. The cathode voltage is from 0 V to -3.0 V vs. SCE at a pH of from 7 to 14. The cathode material typically is stainless steel, chromium, copper and nickel.
