Reduction Kinetics of Chromite Pellets

Abstract:

Plain Chromite and Ore- Coal/charcoal Compositepellets were Reduced in the CO Atmosphere between 1350°C and 1600°C in a Superkenthal Muffle Furnace. the Reaction Followed the Path of First Order Reductionkinetics and the Reduction was under Chemical Reaction Rate Control. Theactivation Energy was Calculated in the Range from 225KJ/mole to 342KJ/mole.The Insitu Carbon Present in the Composite Pellets Motivated the Gasificationreaction of Carbon and the Reduced Fe and Cr Act as the Catalysts to Propagatethe Reduction in the Forward Direction.
