  • Patent number: 10458681
    Abstract: In accordance with exemplary inventive practice, a catalytic system and a temperature swing adsorption system are thermally integrated. The temperature range of the adsorption system is lower than the catalyst operating temperature. Benefits of inventive practice include reduction of total energy consumption and of generated waste-heat. Total energy consumption is reduced by transferring some of the waste-heat generated by the catalytic system into the adsorption system during the sorbent heat-up portion of the sorbent regeneration cycle. The heat is transferred using a thermal reservoir, which accumulates heat from the catalytic apparatus and transfers it to the adsorption apparatus at a later time, and which is repeatedly cycled as the sorbent is cycled. The catalytic system and the adsorption system can be inventively integrated in various ways to reduce the total energy consumed, and/or to modify the sorbent regeneration temperature profile, and/or to obtain an optimum power load profile.

  • Patent number: 9856809
    Abstract: In an internal combustion engine, an exhaust purification catalyst and a hydrocarbon feed valve are arranged in an exhaust passage. When a temperature of the exhaust purification catalyst falls in a first catalyst temperature region (I), a first NOX purification method is performed, while when a temperature of the exhaust purification catalyst falls in a second catalyst temperature region (II), a second NOX purification method is performed. When the temperature of the exhaust purification catalyst falls in a region (IIP) in the second catalyst temperature region close to the first catalyst temperature region, the temperature of the exhaust purification catalyst is made to increase to shift the region in which the temperature of the exhaust purification catalyst falls to the first catalyst temperature region to thereby switch the NOX purification method used from the second NOX purification method to the first NOX purification method.

  • Patent number: 9845714
    Abstract: An electrically-heated catalytic converter includes: a substrate made of ceramic, the substrate including a catalyst coated layer; electrode films made of ceramic, the electrode films being disposed on a surface of the substrate; electrode terminals made of ceramic, each of the electrode terminals being secured to a corresponding one of the electrode films; and external electrodes each attached to a corresponding one of the electrode terminals via a brazing filler metal. A thermal expansion coefficient of the brazing filler metal is equal to or higher than a thermal expansion coefficient of the electrode terminals, and is equal to or lower than a thermal expansion coefficient of the external electrodes. The thermal expansion coefficient of each of the electrode terminals decreases from a portion at which the electrode terminal is joined to the brazing filler metal toward a portion at which the electrode terminal is joined to the corresponding electrode film.

  • Patent number: 9764287
    Abstract: Catalytic cores for a wall-flow filter include juxtaposed channels extending longitudinally between an inlet side and an outlet side of the core, wherein the inlet channels are plugged at the outlet side and outlet channels are plugged at the inlet side. Longitudinal walls forming the inlet and outlet channels separate the inlet channels from the outlet channels. The walls include pores that create passages extending across a width of the walls from the inlet channels to the outlet channels. Catalysts are distributed across the width and length of the walls within internal surfaces of the pores in a manner such that the loading of each catalyst across the width varies by less than 50% from an average loading across the width.
