  • Patent number: 9346018
    Abstract: The invention pertains to a catalyzed particulate filter provided in its entire dispersion side and within its partition walls with a first catalyst being active in selective catalytic reduction of nitrogen oxides, and in its entire permeate side with a second catalyst combination with a catalyst being active in oxidation of ammonia mixed with a catalyst being active in oxidation of carbon monoxide and hydrocarbons and a method for its preparation. The mean particle size of the first catalyst is smaller than the mean pore diameter of the longitudinal porous walls, and the mean particle size of the second catalyst combination is larger than the mean pore diameter of the longitudinal walls. In the example, the first catalyst is a silica aluminum phosphate SAPO-34 promoted with 2% copper and the second catalyst is a mixture of platinum and palladium (molar ratio 3:1) supported on alumina particles and beta zeolite powder with 1.0% copper.

  • Patent number: 8997465
    Abstract: The invention provides a method for purification of exhaust gas from a diesel engine in a system, which comprises a device for selective catalytic reduction and a diesel particulate filter preferably at least partially covered by a catalytic layer installed downstream of the device for selective catalytic reduction. A device for catalytic oxidation is installed upstream of the device for selective catalytic reduction and/or between the device for selective catalytic reduction and the diesel particulate filter. A device for injection of a controlled amount of reductant is installed inlet of the device for selective catalytic reduction, and a device for injection of a controlled amount of hydrocarbon is installed inlet of the catalytic oxidation.
