Abstract: A process and system for separating a fuel stream containing a low concentration of sulfur compounds from a primary fuel stream is disclosed. The process includes isolating a stage-one permeate stream and a stage-one retentate stream from the primary fuel stream, evaporating the stage-one permeate stream at a vacuum, and isolating a stage-two permeate stream and a stage-two retentate stream from the stage-one permeate stream. The stage-two retentate stream is a fuel stream containing low concentrations of sulfur compounds. The system includes a fuel supply, a stage-one separator for separating a fuel stream into a stage-one permeate stream and a stage-one retentate stream, a stage-two separator, a first supply line connecting a portion of the fuel supply to the stage-one separator, and a second supply line connecting the stage-one separator permeate stream to the stage-two separator.

Abstract: A system for producing an auxiliary fuel stream containing a low concentration of sulfur compounds from a primary fuel stream includes a first separation stage to separate a portion of a primary fuel stream into a first vapor permeate stream and a first retentate stream, a first separation stage partial condenser connected to the first vapor permeate stream condensing a portion of the first vapor permeate stream into a first liquid stage stream and a first vapor stage stream, and a second separation stage partial condenser condensing a portion of the first vapor stage stream into a second liquid stage. The first vapor permeate stream is preferable sent through a vapor phase reactive desulfurization catalyst reactor to condition any sulfur compounds present into species that can be easily separated from the fuel stream.

Abstract: A hydrogen generation system is disclosed that includes a fuel reforming reactor generating a hydrogen-rich reformate gas at a temperature greater than 150 C, a pressure swing adsorption (PSA) hydrogen purification unit that separates the reformate gas into a relatively pure hydrogen stream and an off-gas stream, and a catalytic reactor down stream of the PSA unit that converts carbon monoxide (CO) and hydrogen (H2) contained in the relatively pure hydrogen stream into methane (CH4) and water vapor (H2O). The method of purification involves generating a hydrogen-rich reformate gas at a temperature greater than 150 C in a fuel reforming reactor, separating the reformate gas into a relatively pure hydrogen stream and an off-gas stream in a pressure swing adsorption (PSA) hydrogen purification unit, and converting carbon monoxide (CO) and hydrogen (H2) contained in the relatively pure hydrogen stream into methane (CH4) and water vapor (H2O) in a catalytic reactor down stream of the PSA unit.

Abstract: An electrochemical reformer 1 using reactant feed structures having both hydrophilic and hydrophobic regions to provide mechanisms for the wicking of liquid reactants into reformer 1 and for the separation and removal of gaseous products from reformer 1. The electrical reformer 1 may be combined with a fuel cell, a portion of the output of which is used to power reformer 1, to create a compact, portable power source.

Abstract: A method of and system for reducing engine environmental atmospheric pollution emissions from a vehicle having a combustion engine utilizing hydrocarbon fuel for at least one of propulsion and auxiliary electrical power is disclosed. The method basically includes providing an unprocessed bulk fuel storage container and a clean processed fuel tank on the vehicle, supplying the engine for propulsion with fuel from the unprocessed fuel storage container when the vehicle is beyond a predetermined distance from an area having environmental restrictions passing a portion of unprocessed fuel through a desulphurization process to fill a clean fuel storage container while the vehicle is in motion and supplying the combustion engine for one of propulsion and auxiliary electrical power from clean fuel in the processed fuel storage container when the vehicle is within an area having environmental restrictions.

Abstract: A hydrogen generation system is disclosed that has a vaporization section receiving and vaporizing fuel along with water and passing the vapor to a reformer catalyst section heated by a combustor section which generates reformate gas and is fueled by off-gas from a H2 purification unit along with a combustion air source. The off-gas outlet feeds the combustor section in the reformer assembly to heat the catalyst section and the vaporization section. An H2 storage unit connected to the H2 purification unit pure H2 outlet receives the pure H2. The storage unit has an outlet selectively connectable to the reformer assembly process inlet during startup without the need for a spark igniter.
