Abstract: A method for producing a nitrogen oxide storage material that contains at least one storage component in the form of particles of an oxide, carbonate or hydroxide of the elements magnesium, strontium, barium, lanthanum and cerium on a carrier material from the group consisting of doped cerium oxide, cerium/zirconium mixed oxide and aluminum oxide or mixtures of these. The method is carried out by suspending the support material in an aqueous solution of precursors of the storage components, this suspension is then introduced into a hot gas stream, the temperature of which is calculated so that, during a residence time of the suspension in the hot gas stream of less than one minute, the solvent of the suspension is evaporated out and the precursors of the storage components are thermally broken down and converted to the storage components before the storage material that forms in this way is separated from the stream of hot gases.

Abstract: A process for preparing a 3R1-type crystalline anionic clay comprising the steps of: a) preparing an aqueous precursor mixture comprising aluminum trihydrate or a thermally treated form thereof and a magnesium source, the magnesium source is milled before use or when present in the precursor mixture, b) aging the precursor mixture at temperatures in the range 30°-100° C. to obtain the crystalline clay product, and c) optionally shaping the product of step b). Milling of the magnesium source, either alone or in combination with the (thermally treated) aluminum trihydrate, results in a faster reaction and higher conversion to anionic clay. The resulting anionic clay can be obtained by simply drying the slurry retrieved from the reactor. There is no need for washing or filtering, and a wide range of ratios of Mg/Al in the reaction product is possible.

Abstract: An ethylene polymerization catalyst and a catalyst system which provides an ethylene copolymer which, when formed into a film, is characterized by the combination of high stiffness and impact strength. The ethylene polymerization catalyst is formed by contacting a support with an organosilicon compound. The so-treated support is thereupon contacted, in a second step, with a dialkylmagnesium compound or complex. In a third step, the product of the second step is contacted with an alcohol or silane compound. This product, in turn, in a fourth step, is contacted with a transition metal compound. Finally, in a fifth and concluding step, the product of the fourth step is contacted with a Group 13 metal-containing compound. The second and third, as well as the third and fourth contacting steps may be reversed.

Abstract: Inks are formulated for forming anode and cathode catalyst layers and applied to anode and cathode sides of a membrane for a direct methanol fuel cell. The inks comprise a Pt catalyst for the cathode and a Pt—Ru catalyst for the anode, purified water in an amount 4 to 20 times that of the catalyst by weight, and a perfluorosulfonic acid ionomer in an amount effective to provide an ionomer content in the anode and cathode surfaces of 20% to 80% by volume. The inks are prepared in a two-step process while cooling and agitating the solutions. The final solution is placed in a cooler and continuously agitated while spraying the solution over the anode or cathode surface of the membrane as determined by the catalyst content.

Abstract: An exhaust-gas-purifying catalyst wherein a first zeolite loaded with a catalyst metal and a second zeolite unloaded with a catalyst metal are mixed. By actively adsorbing HC onto the second zeolite, it is possible to inhibit the catalyst metal loaded on the first zeolite from being poisoned by HC, and to sufficiently adsorb HC. Accordingly, since the HC adsorbing capability is improved, and since the HC poisoning of the catalyst metal is suppressed, the NOx purifying capability is enhanced and the durability is also upgraded.

Abstract: Improved catalysts for conversion of exhaust from internal combustion engines are produced by providing a unique, promoted support consisting of a mixed-metal-oxide promoter substantially uniformly dispersed as homogeneous crystallites of less than about 100 Å on a high surface area refractory oxide support substrate. The promoted support is made by a process that involves dissolving a combination of a primary metal oxide precursor with the oxide precursor of at least one additional metal and a compatible organic depositing agent, slowly heating to transform the depositing agent into a gel-like matrix coating the substrate in which the mixed-metal-oxide precursor compounds are uniformly distributed and thereafter calcining to burn off the organic matrix and form the appropriate oxide morphology.
