Title: Enabling Desulfarization for Future Compact Jet Fuel (JP-8) Power Sources
Abstract: The U.S. Army has a one fuel policy, which requires the use of logistics fuel for most power and mobility applications. JP-8, the Army’s one and only logistical fuel is a complex hydrocarbon mixture containing many contaminants such as organic sulfur compounds. Fuel cells require clean hydrogen, however, JP-8 has a high sulfur-content so hydrogen produced from JP-8 contains sulfur which poisons a fuel cell unless remediated. Thus, reducing the logistic burden through the integration of more efficient power sources such as autonomous fuel cells is a primary goal of the Army. This presentation will discuss the design and characterization of sorbent materials within the U.S. Army Research Laboratory that can remove organic sulfur contaminants at room temperature directly from the liquid JP-8 and H2S gas phase ≥400 ˚C. This technology may extend the life of the reformer and fuel cell catalysts and enable the removal of additional fuel processing components/steps for compact power sources.
