Abstract:
A catalyst for the oxidation of SO 2 to SO 3 , a process for producing it and its use in a process for the oxidation of SO 2 to SO 3 are provided. The catalyst comprises active substance comprising vanadium, alkali metal compounds and sulfate applied to a support comprising naturally occurring diatomaceous earths, wherein the support comprises at least one relatively soft naturally occurring uncalcined diatomaceous earth which has a percentage reduction of at least 35% in its D 50 value determined in a particle size determination according to the dry method in comparison with the wet method.
Abstract:
The present invention relates to a method for technical extraction of propene from a gas stream containing at least propene and propane, the step comprising bringing the gas stream into contact with an adsorbent material comprising a porous metal-organic structural material containing at least one at least bidentate organic compound that is coordinatively bonded to at least one metal ion, wherein the adsorbent material becomes loaded up with propane and the gas stream thereby exhibits an elevated propene content, wherein the at least bidentate organic component is an imidazolate that is unsubstituted or that contains one or more substituents independently selected from the group consisting of halogen, C 1-6 alkyl, phenyl, NH 2 , NH(C 1-6 alkyl), N(C 1-6 alkyl) 2 , OH, O-phenyl and O-C 1-6 alkyl. The present invention also relates to the use of such a porous metal-organic structural material for technical extraction of propene from a gas stream containing at least propene and propane by way of propane depletion of the gas stream.
Abstract:
The invention relates to the use of a porous metal-organic framework material containing at least one at least bidentate organic compound bound coordinatively to at least one metal ion, said compound being used as a drying agent for reducing or for removing water from an organic liquid.
Abstract:
The present invention relates to a method for producing a porous organometallic framework material by reacting at least one metal compound, the metal being Be, Mg, Ca, Sr, Ba, AI, Ga or In, with at least one at least bidentate organic compound. The invention also relates to the use of such porous organometallic framework materials.
Abstract:
The invention relates to a catalyst containing from 0.1 to 20 mass % rhenium and 0.05 to 10 mass % platinum in relation to the total mass thereof. The inventive method for producing a support for said catalyst consists in a) treating a support which can be eventually pre-treated with the aid of a solution of rhenium compound, b) drying and annealing said support at a temperature ranging from 80 to 600 °C, and c) impregnating the support with a solution of platinum compound and in drying it. The inventive method for producing alcohol by catalytic hydrogenation of carbonyl compound on said catalyst is also disclosed.
Abstract:
The present invention relates to a porous metal organic framework material formed of Mg2+ ions which is coordinatively bonded by 5-tert.-butylisophthalate ions, during formation of a framework structure. The invention also relates to methods for the production and application thereof, for example, for storage, separation, or the controlled release of a substance such as a gas or gas mixture.
