Title: Catalyst for reduction of diesel particulate
Inventor: ITO YUKARI
IPC: B01D53/94
Filed: 1990-07-27
Abstract: PURPOSE:To suppress production of SO3 in a high temp. range by using a catalyst of such a structure that consists of a carrier base body the surface of which is covered with a catalyst carrier layer comprising titanium dioxide (TiO2), and platinum group metals and molybdenum deposited on the catalyst carrier layer. CONSTITUTION:The carrier base body 1 consists of a monolithic carrier base material such as ceramics or metals, foam filter, etc. On the surface of the catalyst base material 1, a catalyst carrier layer comprising titanium dioxide (TiO2) is formed. This catalyst carrier layer 2 contains coexistence of platinum group metals 3 such as Pt, Rh, Pd, etc., and Mo 4. The platinum metals 3 contribute to oxidization of SOF, HC and CO. Mo 3 is supposed to have a function to obstract oxidization of SO2 by the platinum metals 4 and to suppress production of SO3. The catalyst carrier layer 2 comprising TiO2 hardly adsorbs SO3. Thereby, high purifying efficiency for SOF, HC, CO can be maintained and the production of SO3 in a high temp. range can be prevented.

Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To provide an easily produceable copper- and lead-base alloy bearing, which is provided with high corrosion resistance, without arranging any overlay by increasing corrosion resistance of a bearing alloy layer itself. SOLUTION: A copper- and lead-base bearing alloy layer, in which a Pb particle phase is dispersed in a matrix, is connected to a back metal. The bearing alloy layer surface is covered by means of a plating layer which is laminated with either/both of In or/and Sn. Then, a diffusion process is applied, so that In or/and Sn in the plating layer is/are preferentially diffused to the Pb particle phase in the bearing alloy layer, and a diffusion layer with a thickness of 30-300 μm is formed in the Pb particle phase. Because of the bearing alloy layer on which the diffusion layer with a high In/Sn concentration is formed, corrosion resistance can be improved. On the other hand, the plating layer is diffused to vanish.
