  • Method for removing CO, Hand CHfrom an anode waste gas of a fuel cell and catalyst system useful for removing these gases
    Patent number: 9327238
    Abstract: A system for removing CO, H2 and CH4 from an anode waste gas stream from a fuel cell is disclosed. The two catalyst system may comprise a platinum/palladium catalyst and a copper/manganese catalyst. The anode waste stream comes in contact with the platinum/palladium catalyst prior to contacting the copper/manganese catalyst.

  • Oxidation catalyst and method for destruction of CO, VOC and halogenated VOC
    Patent number: 8475755
    Abstract: An oxidation catalyst deposited on a substrate is described for the destruction of CO and volatile organic compounds, in particular halogenated organic compounds, from an emissions stream at temperatures from 250° C. to 450° C. The oxidation catalyst includes at least two platinum group metals, one of which is either platinum or ruthenium, supported on refractory oxides, such as a solid solution of CeO2 and ZrO2, and tin oxide and/or silica.
