Abstract
Amplification of periodic variations of input temperature in a product-inhibited reaction - CO oxidation over CuO-γ-Al2O 3 - was investigated experimentally in an insulated packed-bed reactor. At steady state the temperature profile was elongated compared with that of a reactant-inhibited CO oxidation over Pt/Al2O3, studied elsewhere. Under periodic operation, amplitudes of the resulting travelling temperature waves, monitored downstream from the reaction front, were amplified to a greater extent than those in the reactant-inhibited CO oxidation over Pt/Al2O3. The magnitude of the amplification depended on the perturbation frequency and showed resonance behaviour. The magnitude decreased monotonically with increasing perturbation amplitude.
