The Thermocouples. Copyright: Petr Kluson The image shows a series of thermocouples for temperature monitoring of the single‐pellet string bed reactor. This unique reactor design with a 3‐m long meandering channel integrates the heating/cooling system. It is well suited for accommodating highly exothermic catalytic reactions up to temperatures of 400 °C. The long reactor bed enables to reach high flow velocities and thus allows the investigation of the reactions under industrially relevant conditions in a laboratory environment.
