  • Patent number: 6392065
    Abstract: The invention relates to a method of producing epoxy resins from hydrocarbons with olefinic double bonds, especially alkenes, by heterogeneous catalyzed oxidation in the gaseous phase. According to said method, and oxidic solid catalyst is released which contains iron as its active component at a concentration of 0.001-1% and alkali and/or alkaline earth elements as the promoters. N2O is used as the oxidizing agent. The granulated oxidic solid catalyst, especially on the basis of SiO2 as the carrier, has a specific surface of greater that 50 m2/g. The ratio of the concentrations of the active components to the promoter components is preferably between 1:100 and 10:1. The partial oxidation of hydrocarbons with olefinic double bonds, especially propene, results in propene selectivities of 10-70% at reaction temperatures of 300-500° C. and conversions of 2-30%.

  • Patent number: 6383386
    Abstract: The invention relates to a hydrophobic permeable composite, to a method for producing a hydrophobic permeable composite and to the use of said composite in various processes. Hydrophobic, permeable materials have been known for some time. Plastic materials especially, for example Gore-Tex®, but also materials consisting of other organic polymers are used whenever a material is required to be gas- and steam-permeable but not liquid-permeable. These materials have the disadvantage that they can only be used within a certain temperature range. The inventive composite is characterised by a higher temperature resistance since it consists mainly of inorganic materials. It is also relatively easy to produce since it can be obtained using the sol-gel technique. The inventive composite can be used as a membrane in the oxidation of aromatics, for example in the direct oxidation of benzene to phenol.

  • Publication number: 20020028492
    Abstract: Process for the oxidation of hydrocarbons having 2 to 20 carbon atoms using microorganisms such as bacterial strains such as Rhodococcus ruber KB1, Rhodococcus ruber DSM 7511, Rhodococcus ruber SW 3 or Arthrobacter sp. 11075, their natural mutants or genetically modified mutants. The process can be used for producing oxidation products of hydrocarbons such as alcohols with improved selectivity, and for cleaning up water or soil samples contaminated with hydrocarbons.

  • Publication number: 20020023419
    Abstract: A gas filter, a process for producing a gas filter and the use of the gas filter are claimed. The filtration of gases, in particular of gases which are contaminated by solids, e.g. automobile exhaust gases, is difficult since the solids which have been filtered out block the filter over the course of time. The gas filter of the invention can be used over relatively long periods of time since it is regenerable.

  • Patent number: 6340379
    Abstract: A gas filter, a process for producing a gas filter and the use of the gas filter. The filtration of gases, in particular of gases which are contaminated by solids, e.g. automobile exhaust gases, is difficult since the solids which have been filtered out block the filter over the course of time. The gas filter of the invention can be used over relatively long periods of time since it is regenerable. The improvement achieved by the invention compared to conventional gas filters is that the filter comprises a composite material which can be heated in a simple manner by application of a voltage to the electrically conductive support material of the composite material and thermally decomposable substances which can block the filter can be decomposed. The filter of the invention can be used wherever gases which are contaminated by thermally decomposable solids have to be cleaned.

  • Patent number: 6309545
    Abstract: The invention relates to a permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material contains essentially a porous, permeable support, another constituent having been solidified on and in or on or in said support. Said other constituent essentially contains metallic compounds with elements of the 3rd to the 6th main group. The constituent is solidified to, on or in the support by heating a suspension of the constituent suspended in a metal oxide sol applied on and in or on or in the support. The invention hereby provides a means of producing a permeable composite material in very mild conditions, either by heating strongly for a short period or by heating more moderately for a longer period. The resulting permeable composite material is excellently suited to applications in filtration and membrane technology.

  • Patent number: 6299778
    Abstract: The invention relates to a catalytically active, permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material can be used for separating mixtures of materials. The fact that various catalytically active substances can be incorporated into the material in various ways makes it highly flexible in terms of possible applications with properties which can be adapted to the particular purpose of an application. The inventive composite material can be used as a catalytically active membrane electrode, for example. According to the invention, the material is obtained by solidifying a suspension on and in a porous, permeable support. The production of the material requires either a very short period of heat treatment at temperatures of around 400° C. or treatment for a longer period at very mild temperatures of below 100° C.
