Abstract
Apparatus for evaluating catalysts, including a multicell holder, e.g., a honeycomb or plate, or a collection of individual support particles, is treated with solutions/suspensions of catalyst ingredients to produce cells, spots or pellets holding each of a variety of combinations of the ingredients, is dried, calcined or treated as necessary to stabilize the ingredients in the cells, spots or pellets, then is contacted with a potentially reactive feed stream or batch, e.g., biochemical, gas oil, hydrogen plus oxygen, propylene plus oxygen, CCl2F2 and hydrogen, etc. The reaction occurring in each cell can be measured, e.g., by infrared thermography, spectroscopic detection of products or residual reactants, or by sampling, e.g., multistreaming through low volume tubing, from the vicinity of each combination, followed by analysis, e.g., spectral analysis, chromatography, etc., or by observing temperature change in the vicinity of the catalyst, e.g., by thermographic techniques, to determine the relative efficacy of the catalysts in each combination. Robotic techniques can be employed in producing the cells, spots, pellets, etc.
