Hydrogen Separation from a Logistic-Fuel Reformate Stream

In Phase I, Power and Energy has demonstrated a solution to the problem of sulfur poisoning that can be incorporated in membranes used for hydrogen separation from reformate streams derived from logistic fuels containing up to 10,000 ppm sulfur. The objectives of this Phase II can be summarized as developing and delivering a compact demonstration hydrogen separator capable of producing 50kW(e) of pure hydrogen from logistic fuel reformate that has up to 10,000 ppm of sulfur contamination. This system will have high hydrogen permeability and when operated appropriately will be immune to sulfur contamination up to 10,000 ppm in logistic diesel. The Phase I data demonstrated that Pd membranes can be immune to contamination in excess of 10,000 in logistic fuels. In Phase II, P&E will examine a family of palladium alloys for optimum characteristics that are both sulfur immune and have high permeability’s required for compact Navy shipboard systems. In 12 months from the start of the contract P&E will deliver a 50kW(e) hydrogen separator that is immune to sulfur contamination up to 10,000 ppm in logistic fuels.
