Abstract

The conversion of carbon monoxide to carbon dioxide was measured in a recyle reactor automatically controlled by a computer. Two Pt/SiO₂ catalysts of different dispersion were employed. Isothermal experiments (in which the carbon monoxide inlet concentration was varied) and temperature‐programmed experiments (in which the temperature was varied) yielded multiple steady states and complete hystereses. The rate data were controlled well by three LHHW kinetic models. However only two of them predicted well the transitions from low to high conversion.
