Remote control of reaction rate by radiofrequency heating of composite catalyst pellets

Popis výsledku v původním jazyce

The vapour-phase dehydration of ethanol over alumina has been considered as a model system for demonstrating a novel concept for the "remote control" of an endothermic catalytic reaction. Control of the reaction rate was achieved by forming composite catalyst pellets consisting of porous alumina with embedded metal (Fe) microparticles. Exposing such composite catalyst pellets to alternating magnetic field in the radiofrequency range (900 kHz) resulted in localised heat generation within the catalyst pellets due to induction heating of the iron particles. The effect of the magnetic field power output and reactant flowrate on the steady-state conversion over a differential catalyst bed was systematically investigated. Transient On/Off operation of the reaction was then demonstrated by periodically changing the intensity of the magnetic field and thus controlling the local temperature of the catalyst. This concept enables the reaction product to be formed locally in short bursts, which pr
