Abstract: Novel metal-containing silicates, in particular redox-active as well as crystalline silicates, a process for preparing metal-containing crystalline silicates, as well as use thereof as high-temperature oxidation catalyst or diesel oxidation catalyst. Further, a catalytic composition and a shaped catalyst body which contains the metal-containing crystalline silicates.

Abstract: A catalyst support body containing an SiO2-containing material and a metal selected from the group consisting of alkali metals, alkaline earth metals, rare earth metals and mixtures thereof, wherein the total metal content lies in the range of from 0.5 to 10 wt.-%, relative to the total weight of the catalyst support. Also, a catalyst that comprises a catalyst support body according to the invention and a catalytically active metal, in particular palladium and/or gold. Also, a method for producing a catalyst support, wherein an SiO2-containing material is treated with a metal-containing compound, dried and then calcined. Also, a method for producing a catalyst, in which a solution having a precursor compound of a catalytically active metal is applied to a catalyst support body.

Abstract: In a method of synthesizing a crystalline molecular sieve, a reaction mixture is formed comprising a source of phosphorus, a source of aluminum, at least one organic directing agent and, optionally, a source of silicon and crystallization of the reaction mixture is induced to form a slurry comprising the desired crystalline molecular sieve. The slurry is then maintained in contact with a flocculant for a period of 12 hours to 30 days before the crystalline molecular sieve is recovered from said slurry.
