  • Patent number: 9435241
    Abstract: An object of the invention is to satisfactorily remove solid materials derived from reducing agent and depositing on a wall of an exhaust passage in an exhaust gas purification apparatus for an internal combustion engine equipped with a selective reduction catalyst provided in the exhaust passage of the internal combustion engine and a reducing agent supply apparatus that supplies reducing agent derived from ammonia into the exhaust passage upstream of the selective reduction catalyst. To achieve the object, according to the invention, a fuel supply apparatus that supplies fuel into the exhaust passage upstream of the reducing agent supply apparatus and an ignition apparatus that ignites fuel supplied by the fuel supply apparatus to generate flame are provided. Solid materials derived from the reducing agent are removed by the flame generated by the fuel supply apparatus and the ignition apparatus.

  • Patent number: 9427728
    Abstract: The present invention provides for a device for reducing a volatile organic compound (VOC) content of a gas comprising a manganese oxide (MnOx) catalyst. The manganese oxide (MnOx) catalyst is capable of catalyzing formaldehyde at room temperature, with complete conversion, to CO2 and water vapor. The manganese oxide (MnOx) catalyst itself is not consumed by the reaction of formaldehyde into CO2 and water vapor. The present invention also provides for a device for reducing or removing a particle, a VOC and/or ozone from a gas comprising an activated carbon filter (ACF) on a media that is capable of being periodically regenerated.

  • Patent number: 9364786
    Abstract: A vacuum pump has a discharge port coupled to an abatement chamber for treating an exhaust gas discharged from a chamber of a manufacturing apparatus to make the exhaust gas harmless. The vacuum pump is coupled to a heat exchanger configured to heat an inert gas by using heat generated when the exhaust gas is treated to be made harmless in the abatement part. The inert gas heated by the heat exchanger is introduced into the vacuum pump.

  • Patent number: 9328641
    Abstract: Some embodiments relate to a catalytic assembly for an engine. The catalytic assembly includes a cooling housing that receives a coolant (e.g., seawater). A catalyst housing is disposed within the cooling housing such that the coolant flows between the catalyst housing and the cooling housing. A catalyst substrate is positioned within the catalyst housing such that exhaust gases from the engine flows through the catalyst substrate. The catalyst substrate serves to covert harmful emissions found in the exhaust gases to less harmful emissions. The catalyst housing includes a first fitting and cooling housing includes a second fitting that mates with the first fitting to prevent rotation of the catalyst housing relative to the cooling housing.
