A process for purifying a liquid hydrocarbon feedstock containing organo- sulfur compounds wherein an aqueous sulfuric acid solution containing ions of a transition metal, such as vanadium, chromium, manganese, cobalt, cerium or mixtures thereof, is subject to electrolysis to oxidize the metal ions to a higher oxidation state, the electrolyzed solution is emulsified with the feedstock to achieve oxidation of the organo-sulfur compounds to form water soluble sulfur compounds, gaseous products, resinous products; the spent aqueous acidic solution and the purified hydrocarbon product are separated and the spent aqueous solution is recycled via electrolysis.
Procédé pour l'épuration d'une charge d'alimentation d'hydrocarbures liquides renfermant des composés organosoufrés, selon lequel on soumet à l'électrolyse une solution aqueuse d'acide sulfurique renfermant des ions d'un métal de transition tel que le vanadium, le chrome, le manganèse, le cobalt, le cérium ou leurs mélanges, afin d'oxyder les ions métalliques jusqu'à ce que leur état d'oxydation atteigne une valeur plus élevée, on crée une émulsion de la solution électrolysée et la charge d'alimentation afin de réaliser l'oxydation des composés organosoufrés et de former des composés soufrés hydrosolubles, des produits gazeux et des produits résineux, on sépare la solution acide aqueuse usée et le produit hydrocarboné épuré, et on recycle la solution aqueuse usée par électrolyse.
