  • Oxidation catalyst for lean compressed natural gas engine
    Patent number: 11648534
    Abstract: The present invention provides an oxidation catalyst composition suitable for at least partial conversion of gaseous hydrocarbon emissions, e.g., methane. The oxidation catalyst composition includes at least one platinum group metal (PGM) component supported onto a porous zirconia-containing material that provides an effect on hydrocarbon conversion activity. The porous zirconia-containing material is at least 90% by weight in the monoclinic phase. Furthermore, the PGM component can comprise at least one platinum group metal in the form of colloidally deposited nanoparticles. The oxidation catalyst composition can be used in the treatment of emissions from lean compressed natural gas engines.
    Type: Grant

  • Ruthenium impregnated ceria catalyst
    Patent number: 10895183
    Abstract: The present disclosure generally provides low-temperature nitrogen oxides (NOx) adsorbers used in the treatment of a NOx-containing exhaust gas stream and to methods of preparing and using the same. In particular, the NOx adsorber composition includes an active metal and a metal oxide support, wherein the metal oxide support includes greater than 50% by weight ceria based on the total weight of the NOx adsorber composition, and wherein the active metal includes about 0.01% to about 5% by weight ruthenium based on the total weight of the NOx adsorber composition.
