  • Patent number: 9616384
    Abstract: Described are base metal catalysts that comprise a base metal material in an amount effective to generate an exotherm over a temperature range of 300° C. to 650° C. and to oxidize soot collected by a downstream particulate filter. The base metal catalysts are substantially free of platinum group metals. Emission treatment systems and methods of remediating nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons using base metal catalyst are also described.
    Type: Grant

  • Patent number: 8776499
    Abstract: Provided are exhaust systems, components, and catalytic articles that have been passivated for use in conjunction with diesel engines that includes a NOx abatement system that uses a reductant. These items are passivated in order to minimize degradation of a reductant in their presence when, for example, they have been subjected to temperatures in excess of 650° C.
