摘要： PROBLEM TO BE SOLVED: To provide an element for removing NO x and a NO x removing method reducing power consumption by making the element for removing NO x having a high diffusing capacity of an oxygen ion. SOLUTION: The element for removing NO x comprises a substrate 1 comprising a solid electrolyte, capable of retaining the oxygen ion in the inside of a bonding structure of atoms to each other and exhibiting a conductivity by movement of the oxygen ion itself by application of a voltage; and a positive electrode 3 and a negative electrode 2 formed on a surface of a substrate. The oxygen ion is drawn out from NO x in an atmosphere to reduce it to N 2 in the negative electrode 2, and the drawn out oxygen ion is released from the positive electrode 3 as oxygen. Since the movement of the oxygen ion in the substrate 1 is not the indirect movement through lattice defect but the direct movement of the oxygen ion itself, required energy is small.

摘要： PROBLEM TO BE SOLVED: To provide an economic particulate material clarification material which increases a catching rate of PM with the stable melting in an exhaust gas temperature range of an internal combustion, at the same time increases further an area of contact surface with PM, and, particularly, enables the stable installation in an exhaust system of an automobile. SOLUTION: The particulate material clarification material is composed of a soot trapping component containing at least one selected from silver carbonate, an alkali metal carbonate, an alkaline earth metal carbonate, a rare earth element carbonate, silver halide, an alkali metal halide, and an alkaline earth metal halide, and/or compound salt where two or more selected from them are compositely treated, which is supported on a solid carrier, and a soot clarification component containing at least one selected from silver nitrate, an alkali metal nitrate, an alkaline earth metal nitrate, and a rare earth element nitrate, and/or compound nitrate where two or more selected from them are compositely treated, which is supported on a solid carrier. The soot in PM is trapped in the soot trapping component 2, and the trapped soot is efficiently oxidized and purified by the soot clarification component 3 in the vicinity to become CO 2 for discharge.

摘要： PROBLEM TO BE SOLVED: To produce an exhaust gas purifying catalyst capable of purifying PM (particulates) from a low temperature region, suppressing the decomposition of a molten salt type catalyst, capable of regenerating the decomposed molten salt type catalyst and efficiently purifying NO x in an exhaust gas. SOLUTION: This exhaust gas purifying catalyst comprises a solid carrier 2, the molten salt type catalyst layer 3 supported on the solid carrier 2 and catalyst particles 4 supported on the molten salt type catalyst and a part of the catalyst particles 4 are exposed to the surface of the molten salt type catalyst layer 3. Since the particle size of the catalyst particles 4 is large, a noble metal, or the like, supported on the catalyst particles 4 becomes low in the contact probability with the molten salt type catalyst and the decomposition of the molten salt type catalyst is suppressed. Further, the decomposed molten salt type catalyst is regenerated by produced NO 2 . COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enable effective collection of a particulate matter using a flow- through catalyst, and effectively oxidative combustion of the collected particulate matter without need for large electric power. SOLUTION: An electro static charge part 5 for charging the particulate matter and a collecting part 6 for collecting the charged particulate matter with electrostatic pressure are provided, including fused-salt catalyst for oxidizing and purifying the particulate matter which is fused and collected at a temperature not less than the predetermined temperature at the collecting part 6. The fused-salt catalyst fused at a temperature not less than the predetermined temperature is a liquid phase, and the collected particulate matter, whose contact area with the particulate matter is large, is effectively oxidized and combusted with the fused-salt catalyst. The particulate matter collected by the fused-salt catalyst of liquid phase is prevented from re-scattering even if the electric charge is disappeared.

摘要： PROBLEM TO BE SOLVED: To provide an element for exhaust gas cleaning which is capable of developing a high ternary activity from a low temperature area without using noble metals. SOLUTION: The element for the exhaust gas cleaning is comprised of a substrate 1 comprised of an oxygen ion conductor and a cathode electrode 2 and an anode electrode 3 which are formed with a space each other on the surface of the substrate 1, and constitutes the cathode electrode 2 from a metal oxide and the oxygen ion conductor. The metal oxide is reduced at the cathode 2 by application of voltage to produce many oxygen ions. Also NO in the exhaust gas is reduced to N 2 and produces oxygen ions. Much of the produced oxygen ions pass through the substrate 1 and are transferred to the anode electrode 2. HC and CO in the exhaust gas are oxidized during transferring. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an emission control device capable of greatly reducing the amount of carried noble metal and materializing high purification activity. SOLUTION: A first catalyst 1 carrying noble metal of carried amount 1 g/L or, and a second catalyst 2 carrying no noble metal, and a selector means 5 selecting at least one of the first catalyst and the second catalyst for circulating exhaust gas therethrough are arranged. The selector means 5 is controlled to flow exhaust gas through the first catalyst 1 under a condition that speed of exhaust gas purification reaction in the first catalyst 1 is diffusion controlled speed and to flow exhaust gas through at least the second catalyst 2 under a condition that speed of exhaust gas purification reaction in the first catalyst 1 is not diffusion controlled speed. Purification reaction sufficiently progresses even if number of activity points is extremely small in a diffusion controlled speed range. Necessary reaction speed can be provided even with using a catalyst not carrying noble metal under a condition the reaction speed is not diffusion controlled speed. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To restrain the discharge of NOx drastically even when exhaust gas is heated or the speed of a car is accelerated or decelerated after an internal-combustion engine is started. SOLUTION: The plasma assisting catalytic apparatus consists of a plasma generating unit 1, an NOx adsorbing unit 2 and an NOx removing unit 3 obtained by depositing an element of group IIIb on a porous body. The unit 2 and the unit 3 are arranged in this order from the upstream side of exhaust gas to the downstream. NO in the exhaust gas is oxidized into NOx by the discharge plasma from the unit 1. NOx is adsorbed in the unit 2 when the temperature of the exhaust gas is low, for example, when the engine is started. When the temperature of the exhaust gas becomes high, NOx is released from the unit 2 and the released NOx is reduced and removed in the unit 3. In other words, NOx can be removed efficiently by the synergistic action of the units 2 and 3 under the temperature-transitional condition that the temperature rises or falls.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst by which toxic gas can be removed satisfactorily effectively in a sufficiently wide temperature range, the manufacturing cost of which can be reduced satisfactorily and which can contribute sufficiently to resource conservation. SOLUTION: This catalyst is manufactured by depositing an iron oxide and a noble metal on a carrier containing a metal oxide. This catalyst contains 0.0004-1 mass% noble metal based on the total mass of this catalyst and 0.005-15 parts mass noble metal based on 100 parts mass iron oxide. This catalyst has sufficient activity since the nobel metal assists the catalytic function of the iron oxide even when only a very small amount of the noble metal being an expensive and rare resource is used.
