CONSTRUCTION AND APPLICATION OF A JET-STIRRED LOOP REACTOR

In this paper, a jet-agitated recycling reactor is presented as a special type of back-mixing system, which enables a reliable investigation of catalytic properties without any contamination of the catalyst. Determination of the operation behaviour indicates the manufactured reactor to be equivalent to a perfectly mixed system with high fluid velocities inside the loop. Investigation of the carbon monoxide oxidation over a platinum foil, as a test reaction, demonstrated the system's excellent suitability for applications in catalytic research. Limitations of transport processes in the kinetics observed could be revealed unambiguously, leading to correct interpretation of the data obtained. On this occasion, the measurement device for the gas velocity over the catalyst proved to be very useful.
