Evaluation of Mixed Oxide Catalysts for Lean Diesel Applications

Andrew  Binder, Oak Ridge National Laboratory

Our previous tests on the CuO-Co2O3-CeO2 catalyst has shown it to be an excellent CO oxidizer even in the presence of hydrocarbon inhibitors and MnO2-CeO2 catalysts from the University of South Carolina have shown remarkable sulfur tolerance.  Spurred by these results, we have evaluated series of catalysts composed of mixed-phase oxides for performance in lean diesel applications utilizing the newly released ACEC tech team protocol for Low Temperature Combustion of Diesel (LTC-D).
