Abstract

On the reaction of carbon deposition during the reduction of hematite pellet by CO gas, the reaction mechanism in which the catalytic action of iron carbide was taken into account was proposed, and on the basis of this mechanism an equation of reaction velocity was presented.
Rate constants of carbon deposition were determined experimentally, and it was found that the moles of deposited carbon calculated from the equation of reaction velocity were in good agreement with those obtained experimentally for the case below 650°C.
