Abstract

Oxidation of CO under fast forced temperature oscillations shows increased reaction rate compared to steady state. A maximum increase of 40% is observed relative to steady state. The reaction rate is investigated for varying mean temperature, amplitude and frequency. As function of mean temperature and amplitude a maximum is observed, whereas the reaction rate increases monotonically as function of frequency. The phase difference between the CO, O2 and CO2 signals changes monotonically with varying oscillation parameters.
