摘要：

Infrared imaging is used to visualize nonuniform temperature patterns occurring on a Rh/SiO2 catalyst wafer during the total oxidation of ethylene. Ignition of the catalyst wafer is seen to occur as a propagating reaction front originating at a single point on the wafer. During self-sustained oscillations, the reaction zone contracts, expands, and changes shape. Thermographic data of the oscillations are analyzed by calculating the size and mean temperature of the reaction zone. This analysis reveals that the observed oscillations in the bulk CO2 concentration correlate mainly with changes in the size of the reacting zone.
