Abstract: Electrochemical process for purification and concentration of used sulfuric acid containing hydrocarbon wherein water is added to bring the water content of the acid to between one and two times the stoichiometric amount of water in relation to the amount of carbon present, and electrochemically treating the diluted acid with a current density in the range of 200-2,500 amperes per square foot to cause oxidation of the carbon to carbon dioxide at the anode. Process is particularly applicable to the recovery of used sulfuric acid alkylation catalyst.

Abstract: A PROCESS OF ELECTROCHEMICALLY HALOGENATING HYDROCARBONS IN AN AQUEOUS HYDROHALIC ACID ELECTROLYTE COMPRISING PASSING CURRENT FROM A CATHODE TO AN ANODE IMMERSED IN AN ELECTROLYTE COMPRISING A MIXTURE OF AQUEOUS HYDROHALIC ACID AND 10-90 VOLUME PERCENT OF AN ALIPHATIC ACID OF 2-4 CARBON ATOMS. TYPICALLY, THE PROCESS INVOLVES CHLORINATING AN ALIPHATIC, CYCLOALIPHATIC OR AROMATIC HYDROCARBON IN AN ELECTROLYTIC CELL EMPLOYING GRAPHITE ELECTRODES USING A MIXTURE OF HYDROCHLORIC ACID AND ACETIC ACID. USING THE MIXED ACID ELECTROLYTE PREVENTS RAPID DETERIORATION OF THE ANODES AND INCREASES THE SOLUBILITY OF THE HYDROCARBON STARTING MATERIAL IN THE ELECTROLYTE.
