Technology for the direct desulfurization of unprocessed diesel fuel using regenerable copper-based mixed metal oxide sorbents was developed for incorporation in modular phosphoric acid fuel cell PAFC generators. Removal of greater 60 of the sulfur in diesel fuel was demonstrated, and sorbent sulfur loadings of approximately 1 wt were attained. Preliminary studies indicated that the sorbents are regenerable, with up to 70 of the sorbed sulfur removed during regeneration. Incorporation of this technology into a PAFC power plant should reduce the weight of the sulfur removal unit by a minimum of 25.
