Effective conversion of hydrocarbon fuels to hydrogen requires fuels with ultra-low sulfur contents.  We are developing solid absorbents to selectively adsorb sulfur from fuels.  This ultra-deep desulfurization will also enable fuels to comply with upcoming regulations on sulfur content in gasoline, diesel and jet fuels. The reactor system being used for the desulfurization of gasoline, diesel and jet fuel are shown below.
