Microlith Supported Sulfur Tolerant Catalyst for Autothermal Reforming of E85 Fuel

Abstract

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 (70–80h) using high sulfur doped (100ppm) fuel. At 1.11 O:C and 1.25 S:C, nearly complete conversion and 70%+ reforming efficiency (LHV based) were achieved on stabilized catalysts in the presence of 20ppm feed sulfur. The effect of ceria addition into an alumina based support was also examined.
