Abstract: A process and apparatus for testing material libraries, in particular catalysts, by means of coupled use of at least two analytical methods, preferably IR thermography and mass spectrometry. Owing to the selected arrangement, the disadvantages of the two previously known individual methods are compensated for: the subsequent selectivity determination for selected sections by means of mass spectrometry invalidates the argument against IR thermography, of only being able to determine activities; the rapid integrated determination of potentially “good” materials via IR thermography prevents an excessive loss of time by needing to test all materials of a library successively with the mass spectrometer.

Abstract: The present invention relates to a silver-containing catalyst system, which can be applied for the reaction of substrates with at least one C—C-double bond with at least one oxygen-containing or oxygen-supplying component with formation of at least one epoxide. The silver-containing catalyst according to the invention is characterized in that its activity as well as its selectivity is significantly increased with respect to the target product compared with the silver-containing catalysts of the state of the art, as a consequence of the process for the manufacture according to the invention, in which the synthesis of a silver-amine complex is carried out in absence of light and at temperatures below room temperature.

Abstract: The present invention relates to a novel catalyst comprising at least one support material, rhodium as active metal either alone or in combination with further active metals from the platinum metal group and also at least one rare earth oxide as promoter, where the mass ratio of rhodium to the sum of further active metals from the platinum metal group is at least 1:4.5. In contrast to the catalysts of the prior art, aging or deactivation caused by sulphur-containing deposits can be minimised in the catalyst of the invention. The present invention further provides a method of purifying exhaust gas from internal combustion engines which are predominantly operated in a lean mode and in which the catalysts of the invention are used in a rich-lean cycle.

Abstract: Process for the detection of a product in the discharge of a catalytic material of a plurality of catalytic materials which are exposed to a reaction gas, whereby an adsorbent selective for the product to be determined is disposed in the discharge of each catalytic material, which changes at least one of its properties through the contact with the product to be determined and the change in the property of the adsorbent is then ascertained.
