摘要： A catalyst, which is capable of controlling not only HC, CO and NO.sub.x, but also H.sub.2 S emission from the tail pipe of catalytic converter automobiles, is made of platinum-group metals promoted by rare earth oxides and containing a metal ferrite. The ferrite is present in an H.sub.2 S gettering amount and in an amount up to about 20 weight % of the catalyst. The catalyst comprises an alumina support and is applied as a washcoat to a substrate, such as a honeycomb monolith made from ceramic or metal.

摘要： An optimum washcoated ceramic monolith for treating automotive exhaust gases is made by(a) specifying the reactants, process conditions and desired time on stream;(b) determining from the parameters in step (a) the pore size distribution and thickness of the washcoat to produce the desired auto exhaust conversion;(c) preparing a washcoat catalyst with an alumina having the desired pore size distribution; and(d) applying the prepared washcoat catalyst to a ceramic or metal monolith to produce a finished automotive exhaust gas catalyst.Following this process the optimized washcoated catalyst can then be used to treat automotive exhaust gases.

摘要： A catalytic converter body having a jacket tube, a plurality of non-nestable foil leaves having inner and outer ends defining a leaf length, the outer ends being connected to the jacket tube and radiating inward to provide flow passages generally transverse to the leaf length, and a pliant central core joined to the inner ends of the radiating foil leaves. The catalytic converter body has a natural frequency of between 10 and 100 hertz. The catalytic converter is formed by assembling a plurality of non-nestable foil leaves by interconnecting proximal ends of the foil leaves to provide a continuous flexible strip of overlapping foil leaves in which opposite the distal ends of the leaves extend freely. The strip of foil leaves is then formed into a pliant central core permitting movement of the inner ends relative to each other, and the leaves are arranged to lie in curved paths radiating outwardly from the interconnected proximal ends away from a central area to provide flow passage cells generally parallel to the leaf ends. Thereafter, the distal ends of the leaves are connected to a jacket tube.
