The effect of surfactants on the interfacial rates of reaction of CO2 and CO with liquid iron oxide

摘要

The 14CO2-CO isotope exchange technique has beenused to measure the rates of dissociation CO2 on liquid iron oxidecontaining the surface active components P2O5 or Na2O, principallyat 1673 K. The apparent first-order rate constant is found to decreasemonotonically with small additions of P2O5 up to factor of about 4 at3.5 mol pct.
