Abstract: | We are presenting an effective method to prepare and test heterogeneous catalysts much faster than by the conventional way.
A catalyst array was prepared via an incipient wetness method by combination of different amounts of Pt, Zr, and V on Al2O3 by means of an automatic liquid handler. For catalytic testing for methane oxidation a ceramic monolith reactor module, the
channels of which contain the different catalyst compositions, was developed in which up to 250 catalyst compositions can
be prepared and tested in parallel. Gas samples from each channel of the monolith were analysed sequentially by a mass spectrometer
by moving the QMS inlet capillary into the channels using a three-dimensional positioning system which works at high temperatures.
By comparison of the testing results with experiments carried out in flow reactors it is shown that the monolithic reactor
is an efficient tool for fast screening of heterogeneous catalysts.
