ABSTRACT:
A process for removing sulfur from hydrocarbon feeds, including the steps of providing a hydrocarbon feed containing sulfur; providing a cell having two compartments and a membrane separating the compartments; flowing a hydrogen source through one compartment; flowing the hydrocarbon feed through the other compartment; applying a current across the hydrogen source compartment whereby hydrogen diffuses through the membrane from the hydrogen source to the hydrocarbon feed, whereby the hydrogen reacts with sulfur to form H2S and produce a treated hydrocarbon.
