Under a U.S. Army program, PCI has developed autothermal reforming catalysts for E85 to provide stable performance in the presence of fuel sulfur as well as corrosion inhibitors. The catalysts build on PCI’s Microlith™ catalyst technology and used PCI’s proprietary formulations. A stable performance was demonstrated through short-term testing using high sulfur doped fuel. At 1.11 O:C and 1.25 S:C, nearly complete conversion and reforming efficiency (LHV based) were achieved on stabilized catalysts in the presence of feed sulfur. The effect of ceria addition into an alumina based support was also examined.
