Patents by Inventor Edgar V. Huennekes

Edgar V. Huennekes has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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
    Filed: January 23, 2015
    Date of Patent: April 11, 2017
    Assignee: BASF SE
    Inventors: Martin Kalwei, Edgar V. Huennekes
  • Patent number: 9468915
    Abstract: Described are SCR catalyst systems comprising a first SCR catalyst composition and a second SCR catalyst composition arranged in the system, the first SCR catalyst composition having a faster DeNOx response time when exposed to ammonia than the second catalyst composition and the second SCR catalyst composition has a higher steady state DeNOx performance than the first catalyst composition. The SCR catalyst systems are useful in methods and systems to catalyze the reduction of nitrogen oxides in the presence of a reductant.

  • Patent number: 9260995
    Abstract: Provided is a particulate filtration apparatus for removing combustible and noncombustible particulate matter from a lean burn engine exhaust gas stream containing particulate matter. The apparatus comprises a cyclone body with a roughened surface on the inner walls designed to trap and agglomerate the combustible particulate matter. A catalyst, selected from a selective catalytic reduction catalyst, an ammonia oxidation catalyst, a hydrolysis catalyst, an oxidation catalyst, a three-way catalyst, and combinations thereof can be coated on the roughened surface. Also provided is a system and methods for treating an exhaust gas stream.

  • 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.

  • Patent number: 8318286
    Abstract: Embodiments of the invention pertain to a catalyst, which may be used in a catalytic converter for treating a gas stream containing pollutants. In an embodiment, the catalyst comprises a substrate having a plurality of axially enclosed channels defined by the porous wall elements extending between an inlet end and an outlet end. Washcoat particles are disposed substantially within the pores of the walls, and the surfaces of the wall elements have a porous, rough texture after coating with the washcoat and substantially no fillets formed on the channels.
