The present invention relates to a method of testing catalysts and catalyst systems via a plurality of stations in which each station can accommodate a common reactor module in order to accomplish unattended, automated, rapid serial experimentation. The method includes the steps of: providing within a purged chamber a storage station of pre-loaded catalyst reactors, a hydrocarbon reaction station, one or more additional pre-treatment and/or post-treatment stations in series with said hydrocarbon reaction station, and a robotic means for moving catalyst reactors within the purged chamber between stations, pre-treating the pre-loaded catalyst reactor with a treatment gas in the post-treatment station, reacting the pre-loaded catalyst reactor with a hydrocarbon reactant in the hydrocarbon reaction station, post-treating the pre-loaded catalyst reactor with a treatment gas in the post-treatment station, and repeating the foregoing steps such that the pre-treating, reacting and post-treating steps occur simultaneously for two different pre-loaded catalyst reactors. The advantages of the present invention include improved accuracy, reproducibility and quality of test data generated, increased testing throughput rate, providing for automated unattended operation of the device, providing for the ability the ability to program a variety of sequences and settings, providing for the combination of a variety of processes (pre-treatment, HC reaction testing, post-treatment, aging, and characterization), and providing for higher temperature operation. The method finds application in laboratory test environments, and in particular in high throughput testing environments.
