    摘要： A process for applying a coating to honeycomb structures in an exhaust gas converter which contains two such honeycomb structures in a common housing or enveloping tube which are arranged one after the other and which are separated from each other by a gap. The coating dispersion is first supplied from one end of the exhaust gas converter up to the gap between the two honeycomb structures. Then excess coating dispersion is driven out using a blast of air from the direction of the uncoated honeycomb structure. To coat the second honeycomb structure, the exhaust gas converter is inverted and the coating dispersion is then applied in the same way but from the uncoated end. Following the dispersion coating procedure, production of the catalyst is completed by drying and optionally calcining.

    摘要： An oxidative diesel control catalyst is disclosed which has a high conversion rate for hydrocarbons and carbon monoxide and an inhibited oxidation effect on nitrogen oxides and sulfur dioxides and which contains a monolithic catalyst element with throughflow passages of ceramic or metal coated with an activity-promoting dispersion coating of the fine-particle metal oxides aluminum oxide, titanium oxide, silicon oxide, zeolite or mixtures thereof as support of the catalytically active components, the active components being present in the form of platinum, palladium, rhodium and/or iridium doped with vanadium or in contact with an oxidic vanadium compound. The reduced oxidation effect on sulfur dioxide is obtained by virtue of the fact that the fine-particle metal oxides are surface-modified aluminum oxide, titanium oxide, silicon oxide, zeolite or mixtures thereof. The surface modification is a coating of the specific surface of the metal oxides with a layer of titanium dioxide or silicon dioxide of 1 to 5 monolayers.

    摘要： Monolithic catalysts with a metal carrier that includes a catalytically coated matrix having at least one stack of several sheet-metal strips of corrugated or alternately corrugated and flat metal strips folded or intertwined with one another are described. The free ends of the metal strips are connected by a joining process with a surrounding jacket tube of any required cross-section. The monolithic catalyst is produced very economically and with a catalytic coating that has a uniform thickness. The at least one stack of sheet-metal strips required for the monolithic catalyst with a metal carrier is assembled from coated metal ribbons cut to length so as to form metal stacks. The stacks may be folded and/or intertwined with themselves or with one another so as to form the matrix. The matrix with intertwined and coated strips is inserted into the jacket tube and the free ends of the metal strips are secured by joining to the jacket tube. The coated metal strips may be formed by coating long metal ribbons with catalytic coating in a continuous operation prior to cutting the ribbons to the required length. The metal ribbon is also preferably corrugated prior to the coating step but can also be corrugated after the coating step. In another embodiment, the matrix is formed of a single, continuous and at least partially corrugated metal strip which is folded on to itself so as to form a stack arrangement.

    摘要： A monolithic or honeycomb-catalyst, in particular for purifying the exhaust gases of internal-combustion engines, composed of an inert ceramic or metallic support traversed by parallel flow channels, a layer disposed thereon and composed of catalysis-promoting metal oxide and a catalytically active component supported by the metal oxide, wherein the concentration of the catalysis-promoting metal oxide increases from the periphery to the central axis of the support. Alternatively, the catalysis-promoting metal oxide is essentially equally distributed between central axis and periphery of the support, but concentration of catalytically active component increases from the central axis to the periphery of the support.
