Opis

El-Dekhaila iron Co. imported the pellets from the outside of Egypt, during the transportation from outside to Company, lot of fine (waste pellets fine) formed, this fine was not suitable for the reduction inside the furnace of reduction. Hydrogen has been proven to be a good reductive agent as well as an environment-friendly material. This book was conducted to focus on production of El-Dekhaila iron oxide waste in different forms (briquette and pellets) and reduced it by hydrogen in the temperature range 700 to 950 oC. In reduction kinetics study the most satisfactory model was done to take the slope of the initial linear region of fractional reduction vs. time curve as a measure of rate constant (k). In k vs. 1/T plots were straight line from which Activation Energy was calculated.
