摘要： A catalyst for purifying an exhaust gas includes an upstream side catalyst and a downstream side catalyst. The upstream side catalyst is disposed on an upstream side with respect to an exhaust gas flow, and the downstream side catalyst is disposed on a downstream side with respect thereto. The upstream side catalyst includes a first loading layer, being composed of an alumina containing Ba and La at least, and a first noble metal, being held by the first loading layer and being at least one member selected from the group consisting of Pd, Pd and Rh and Pd and Pt. Alternatively, in addition to the aluminum, the first loading layer can be composed of Ce, a solid solution of Ce and Zr and a solid solution of Ce, Zr and Y in an amount as less as possible. The downstream side catalyst includes a second loading layer, being composed of at least one member selected from the group consisting of an alumina containing La, Ce, a solid solution of Ce and Zr and a solid solution of Ce, Zr and Y, and a second noble metal, being held by the second loading layer and being composed of at least one member selected from the group consisting of Pt, Pd and Rh.

摘要： A catalyst for purifying exhaust gases comprises a catalyst carrier made of potassium titanate and a noble metal loaded on the catalyst carrier. The catalyst carrier is substantially free from alumina. This catalyst can oxidize at least hydrocarbons in exhaust gases at a high catalytic activity even at low temperatures, and at the same time can suppress SO.sub.2 from converting into sulfates. This catalyst does not employ substance like alumina exhibiting solid acidity as a catalyst carrier. Further, this catalyst can be used for purifying exhaust gases from diesel engines to suppress particulates and sulfates from being emitted, and to improve conversions of hydrocarbons and carbon monoxide.

摘要： A device and a method which is capable of uniformly coating, without waste, any flow passages formed in a raw material with a slurry even if a slurry having high viscosity is fed thereto by an amount required for the use of coating without excess and shortage. When the slurry (S) fed to one end of the base material (M) in which a large number of flow passages (2 . . . ) are formed parallel with each other is forced into the flow passages (2 . . . ) by an air pressure to coat the inner walls (2w) of the flow passages, the slurry (S) is fed from a slurry feeding device (6) by a required amount to a slurry storage part (5) formed at the upper surface part of the base material (M) disposed so that both ends of the flow passages (2 . . . ) can be opened in the upper and bottom surfaces thereof. Then, before the slurry (S) is forced into the flow passages (2 . . . ), a centrifugal force and vibration are allowed to act on the slurry (S) by a liquid level uniformalizing mechanism (7) to uniformalize the level of the slurry.
