Abstract
This invention relates to the partial hydrogenation of sulfur containing petroleum feedstreams by electrochemical means. The partially hydrogenated feedstream is then conducted to processes for either conversion and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process or adsorption and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process.
