  • DIESEL OXIDATION CATALYST WITH ENHANCED HYDROCARBON LIGHT-OFF PROPERTIES
    Publication number: 20230372905
    Abstract: The present disclosure relates to oxidation catalyst compositions for use in a close-coupled diesel oxidation catalyst (ccDOC) application, in which the ccDOC can function as a heat generator under high space velocity conditions. The oxidation catalyst compositions include a high surface area support material doped with at least one metal oxide, and a platinum group metal (PGM) supported on the doped high surface area support material.

  • Porous catalyst washcoats
    Patent number: 9868088
    Abstract: Catalyst washcoats with improved porosity and methods for making the washcoats are provided. The process comprises incorporation of an oil-in-water macroemulsion into the catalyst slurry prior to washcoating the carrier substrate, and calcining the washcoated carrier substrate to remove the oil-in-water macroemulsion. Also provided are catalyst articles comprising the washcoat and methods for abatement of exhaust gas emissions.
