Abstract
This invention relates to a process for electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams selectively to mercaptan compounds that can then be more easily removed from the electrochemically treated product stream by either caustic extraction or thermal decomposition of the thiol functionality to hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means in the substantial absence of hydrogen and in the substantial absence of water.
