  • Patent number: 9005560
    Abstract: A method to produce a NOx trap composition, and its use in a NOx trap and in an exhaust system for internal combustion engines, is disclosed. The NOx trap composition is produced by heating an iron-containing zeolite in the presence of an inert gas and an organic compound to produce a reductively calcined iron/zeolite. A palladium compound is then added to the reductively calcined iron/zeolite, and the resulting Pd—Fe/zeolite is then calcined at 400 to 600° C. in the presence of an oxygen-containing gas to produce the NOx trap composition. The NOx trap composition shows low temperature NO capacity below 200° C., as well as an additional NO storage temperature window in the 200 to 250° C. range.

    Abstract: A process for producing alumina and other aluminia products where the formation of a Schiff base imine by reaction of a orgaonaluminum amide or imide oligomer with a carbonyl compound is promoted by the Lewis acid character of the oligomer. The water byproduct of the Schiff base serves as an in situ reagent for subsequent hydrolysis and sol-gel condensation of the aluminum species with concomitant production of alkane. The imine then is washed from the alumina with a suitable solvent. Any of a number of primary amines and aldehydes or ketones may be reagents. Calcining of the sol-gels yields high surface area alumina as characterized by scanning electron microscopy, and gas physisorption measurements. Microporous and/or mesoporous alumina is obtained depending on synthesis conditions. Alumina microspheres are obtained under certain conditions.

    Abstract: Activated alumina agglomerates having a crush resistance of at least 12 daN, measured on that fraction thereof having a mean diameter ranging from 3 to 4 mm, and an adsorptive capacity greater than 18% by weight, well adopted as adsorbents in a wide variety of purification processes, are prepared by agglomerating activated alumina particulates, maturing the resulting agglomerates in the presence of a complexing agent for the cation Al.sup.3+, and then thermally treating the matured agglomerates at a temperature ranging from about 100.degree. to 500.degree. C.

  • Patent number: 5583085
    Abstract: Dehydroxylated oxide (e.g. silica) particles are obtained by reacting oxide particles, having surface hydroxyl groups, with a dialkylcarbonate or diarylcarbonate. The resulting products have surface alkoxy or aryloxy groups and significantly reduced hydroxyl content. The treated oxide particles are especially suitable for use as catalyst supports, and especially as polyolefin catalyst supports.

  • Patent number: 5539135
    Abstract: Hydrophobicized double-layer hydroxide compounds may be produced if double-layer hydroxide compounds of the general formula (I): [M.sup.(II).sub.1-x M.sup.(III).sub.x (OH).sub.2 ] A.sub.x.n H.sub.2 O, in which M.sup.(II) is a divalent metal cation, M.sup.(III) is a trivalent metal cation, A is an equivalent of a monobasic and/or multibasic inorganic acid, x is a number from 0.2 to 0.5 and n is a number from 0 to 10, are reacted at elevated temperature and under autogenous pressure with at least one carboxylic acid or its salt and the reaction product is then dried. The hydrophobicized double-layer hydroxide compounds obtained by this process are suitable as catalysts for the alkoxylation of compounds with active hydrogen atoms or of fatty acid esters.

  • Patent number: 5179060
    Abstract: A method of making a three-way catalyst based on platinum group metals, comprisng: (a) impregnating an alumina substrate with a platinum group metal ion by contacting such substrate with an aqueous solution containing the platinum group metal in an amount of 0.1-5% by weight of alumina substrate and a water soluble acid that forms RCOOH with R being an alkyl or equivalent, said acid being present in an amount of 10-120% by weight of the alumina substrate, the pH of said solution being less than 4.0; and (b) drying and calcining the wetted substrate without sintering said substrate.The three-way catalyst construction based on platinum group metals has enhanced catalytic activity. It comprises an alumina substrate and a platinum group metal impregnation layer thereover, said impregnation layer being comprised of raft-like particle structures, each having increased metal density resulting from the nesting of both small and large metal particles within a given volume.
