ABSTRACT:
A process for treating hydrocarbon feeds includes the steps of providing a hydrocarbon feed containing sulfur and/or metalloporphyrins; 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 and/or metalloporphyrins to form H2S and convert such metalloporphyrins into dissolved metals and a free metal porphyrin, and produce a treated hydrocarbon.
