摘要： PROBLEM TO BE SOLVED: To provide a filter catalyst for cleaning exhaust gas which efficiently collects PM (particulate matter), and has a uniformly carried catalytic metal resulting in efficient continuous oxidative burning of the collected PM. SOLUTION: An exhaust flow passage has a filter introduction part 100 for introducing exhaust gas into a filter and a filter bypassing part 200 for bypassing the filter introduction part 100. A filter is constituted in such a manner that a catalyst layer containing a catalytic metal-carried porous oxide is formed on a metallic plate provided with a through-hole 4 penetrating the front and back of the metallic plate and the diameter of the through-hole 4 is reduced to ≤200 μm or the through-hole is plugged by the catalyst layer. When the pressure in the filter introduction part 100 rises, exhaust gas flows through the filter bypassing part 200, so that the pressure loss can be restrained from increasing. PM is collected by the catalyst layer formed in the through-hole 4 and the collected PM is efficiently burned since the catalyst layer is heated uniformly and the catalytic metal is also activated uniformly.

摘要： PROBLEM TO BE SOLVED: To provide a compact exhaust emission control device having high emission control performance for PM while suppressing the rise of exhaust gas pressure loss. SOLUTION: A semi-filter structure 1 having a filter route for flowing exhaust gas therein through a filter and a filter bypass route bypassing the filter route is disposed on the upstream side, and a filter catalyst 2 of wall flow structure is disposed on the downstream side. Since a part of the PM in the exhaust gas is collected by the semi-filter structure 1, the stacked amount of the PM in the filter catalyst 2 is reduced to suppress the lowering of the catalytic activity of the filter catalyst 2. Also, the rise of the exhaust gas loss can be suppressed by the filter bypass route. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To further improve PM (Particulate Matter) removing capability, pressure loss detection sensitivity, and durability of NOx removing capability.
SOLUTION: A catalytic layer containing a first carrier 2 with an average particle diameter of ≤1 μm, a 2nd carrier 3 with an average particle diameter in the range of 1/20 to 1/2 of the average pore diameter of the cell partition and a catalytic metal is formed on the surface of a cell partition 12 having fine pores with the average pore diameter of 20 to 40 μm and on the inner surface of the fine pores. The catalytic layer has parts where the second carrier 3 exists and does not exit, and its surface is uneven. The 2nd carrier 3 does not easily enter the fine pores with the diameter of ≤20 μm, and is unevenly distributed on the cell partition surface or in fine pores with a large diameter. As a result, the PM collides with raised sections and is easily caught, which increases the chances of contact with the catalytic metal.

摘要： PROBLEM TO BE SOLVED: To eliminate soot in the exhaust gas from a diesel engine without increasing the amount of emissions of NO X or particulates. SOLUTION: The exhaust gas of the diesel engine 1 is guided to an oxidation catalyst 5, and the NO in the exhaust gas is converted into NO 2 . Then the soot in the exhaust gas is collected by a particulate filter 7, and the exhaust temperature is raised while maintaining an exhaust air-fuel ratio at the level of a lean air-fuel ratio. Then the collected NO 2 in the exhaust gas and the soot are forced to react with each other to combust the soot, and the NO generated by the reaction is absorbed by an NO X -absorber 9 arranged on the downstream side of the particulate filter, and is eliminated from the exhaust gas.
