Abstract:
The present invention relates to a process for preparing a porous metal organic framework comprising at least two organic compounds coordinated to at least one metal ion, which comprises the steps (a) oxidation of at least one anode containing metal corresponding to the at least one metal ion in a reaction medium in the presence of at least a first organic compound, where the first organic compound is an optionally substituted monocyclic, bicyclic or polycyclic saturated or unsaturated hydrocarbon in which at least two ring carbons are replaced by heteroatoms selected from the group consisting of N, O and S, to form a reaction intermediate containing at least one metal ion and the first organic compound; and (b) reaction of the reaction intermediate at a prescribed temperature with an at least second organic compound which coordinates to the at least one metal ion, where the second organic compound is derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid.

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 DEG 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.

The invention relates to a method for producing propene from propane. Said method comprises the following steps: A) a feed gas stream (a) containing propane is prepared; B) the feed gas stream (a) containing propane, is introduced with optionally water vapour and optionally, an oxygen-containing gas stream into a dehydrogenation zone and then the propane is dehydrogenated to form propene, and a product gas stream (b) containing propane, propene, methane, ethane, ethene, hydrogen, optionally carbon monoxide, carbon dioxide, water vapour and oxygen, is obtained; C) the product gas stream (b) is cooled, optionally compressed and then water vapour is separated by condensation and a product gas stream (c) depleted in water vapour is obtained; D) the product gas stream (c) is brought into contact with a selectively active adsorber which selectively adsorbs propene in the selected adsorption conditions, and an adsorber charged with propene and a gas stream (d2) depleted in propene and containing propane, methane, ethane, ethene and hydrogen, carbon monoxide and carbon dioxide are obtained; E) a gas stream (e1) containing propene is released from the adsorber charged with propene by reducing the pressure and/or heat of the adsorber.
