The present invention relates to a porous inorganic body comprising pores A having a pore size Sin the range of from 0.005 to 20 micrometer and a total pore volume V, and comprising pores B having a pore size Sin the range of from more than 20 to 1000 micrometer and a total pore volume V, wherein the total pore volume of the pores having a pore size in the range of from 0.005 to 1000 micrometer is Vand wherein the ratio R=V/Vis in the range of from 0.3 to 0.7 as determined via mercury intrusion porosimetry.

Porous inorganic body

Supported noble metal-comprising catalysts which can be obtained by a1) application of a noble metal compound, optionally in admixture with additives acting as promoters, to a support material, then drying, and a2) application of a reducing agent to a support material, then drying, wherein steps a1) and a2) are repeated simultaneously or in alternating turns, or wherein either of the compounds is applied entirely and then the other one is applied entirely, b) optionally afterwards drying of the resulting product, and c) subsequent calcination, its use, especially for oxidative dehydrogenation and a process for producing it.

Supported noble metal-comprising catalyst for oxidative dehydrogenation or epoxidation

Process for producing a supported silver catalyst, which comprises (a) reacting oxalic acid with an alkali metal base in a solvent, preferably water, to the second equivalence point of oxalic acid to give alkali metal oxalate; (b) reacting the alkali metal oxalate obtained according to (a) with silver salt in a solvent, preferably water, to give silver oxalate; (c) forming a complexation of the silver oxalate obtained according to (b) with a diamine compound in a solvent, preferably water, to give a diamine-silver oxalate complex.

Process for producing a supported silver catalyst

The present invention relates to a catalyst for preparing alkylene oxides, which is a supported silver catalyst having a novel promoter combination. The present invention further relates to a process for producing the catalyst and the use of the catalyst for the oxidation of alkylenes to alkylene oxides. In addition, the present invention relates to a process for preparing ethylene oxide from ethylene, which comprises the oxidation of ethylene in the presence of the stated catalyst.

Catalyst for the epoxidation of alkenes

This invention relates to a process, comprising reacting ethylene and oxygen or a source of oxygen in the presence of a catalyst in a reactor to form a product comprising ethylene oxide, wherein the catalyst contains silver or silver compound and a support and the catalyst is in the form of particulate solids having a mean particle diameter from 1 to 1000 &#x3bc;m and wherein the molar ratio of oxygen to ethylene is from 1:4 to 10:1.

Process for making ethylene oxide

The present invention relates to a shaped catalyst body for preparing ethylene oxide, which comprises at least silver and rhenium applied to an alumina support, and also to a process for producing it, wherein the alumina support has the geometry of a hollow cylinder and the shaped catalyst body has a rhenium content Cand C/ppm by weight, based on the wall thickness of the hollow cylinder din mm, and calculated as element, in the range 120&#x2266;C/d&#x2266;200.

Process for producing a catalyst for the oxidation of ethylene to ethylene oxide

The invention relates to a process for producing a catalyst for the oxidation of ethylene to ethylene oxide, which comprises a) providing a support which comprises alumina and has been impregnated with silver or with a silver-comprising compound and has a temperature T; and b) heating the impregnated support from the temperature Tto a temperature Tat a heating rate of at least 30 K/min, and also the catalyst itself which can be obtained by this process.

Supported noble metal-comprising catalysts which can be obtained by

Supported noble metal comprising catalyst for oxidative dehydrogenation or epoxidation

The present invention relates to the use of a zeolite catalyst comprising at least one transition metal and in addition sulfur and/or phosphorus atoms for reducing the content of nitrogen oxides in a gas, and also to a process for reducing the content of nitrogen oxides in a gas by bringing this gas into contact with such a zeolite catalyst.
