Abstract

In order to determine the reduction velocity of hematite pellet by CO gas, experiments of the reduction were conducted by use of thermobalance over the range of temperature where carton deposition might take place simultaneously. The rate constant of the reduction was determined, and the value of activation energy was obtained as 18.51kcal/mol.
It was found also that the moles of deposited carbon increased with the increase in temperature for the case below 600-650°C, but the moles decreased gradually for the case beyond these temperatures.
