Abstract

The purpose of this study is to understand the fundamental mechanism and reaction kinetics of the CO-ilmenite reaction. Carbon monoxide is an important reducing gas because first of all, it is an intermediate product in any carbothermal reduction process. Secondly, CO reduction is potentially an attractive process in which a variety of initial carbonaceous compounds can be used as primary reducing agents for the production of CO. The results indicate that the process involves the migration of iron towards the grain boundaries during the reduction, causing separation and segregation of the products: iron and titanium dioxide (rutile) in the grain level. TYhe temporal profiles of conversion indicate the presence of three different stages during the reduction reaction: induction, acceleration, and deceleration.
