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. The reactor design permits, firstly, the integral recording of the entire reactor through a window which is transparent for the corresponding method and, secondly, permits the simultaneous, automated application of a second analytical method (for example mass spectrometry) to selected materials of a material library, which have been rated as active by the optical method. In the case described, the optical method provides information on the material activity for a set problem, and the second analytical method determines the selectivity of the materials.

摘要:
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.
