Relationship between Electronic Conductivity of Iron Oxide–Containing Slags and Reaction Kinetics with CO-CO2

The reaction rate of CO-CO2 with FeOx-containing slags in its elementary steps involves charge exchange between slag and adsorbed gas species. Several studies have attempted to explain the complex dependence of reaction kinetics on slag composition and temperature by relating charge transfer properties of slag, namely, electrical conductivity, to the reaction rate. It is discussed in this work that the electrical conductivity and charge …
