Langmuir-Hinshelwood Reaction in a PFR
Oxygen oxidizes CO to CO2 on a supported metal catalyst in an isothermal plug flow reactor. Use buttons to select plots of partial pressures (P), surface coverages (q), or reaction rate as a function of distance down the reactor. Use sliders to vary the “temperature”, the “CO feed partial pressure”, and the “O2 feed partial pressure”. Because the rate-determining step is the reaction of adsorbed CO and adsorbed O, and because CO adsorbs more strongly than O, increasing the CO feed partial pressure can decrease the rate of CO2 formation. This happens when the CO surface coverage becomes much higher than the O surface coverage.
