Description:
Two ten-channel fixed-bed reactor systems were developed for high-throughput screening of new Deacon catalysts. The sequential ten-channel reactor allows the determination of the activity of up to ten catalysts per day. With a ten-channel ageing reactor the long-time stability of catalytic activity can be tested in parallel. Both systems are robust, quite resistant against corrosion, and use the identical reaction tubes which enable the direct transfer of a catalyst from one to the other system. A mass-spectrometric pulse method has been developed and applied successfully for the analysis of the corrosive product gas mixture of the Deacon reaction. The application of high-throughput methods and reactors for the Deacon reaction poses a special challenge for researchers because of the corrosive reaction gas mixture. The development of two new multi-reactor systems for reaction screening and catalyst ageing of highly corrosive reactions is described. Potential error sources and problems are discussed.
