Reduction Kinetics of Iron OreGraphite Composite Pellets: Some Studies on the Reduction Kinetics of Iron OreGraphite Composite,Used
Delivery time: 8-12 business days (International)
The rate of reduction of iron oregraphite composite pellets under inert and reducing atmospheres has been investigated in a tailor made thermogravimetric packedbed reactor. A very low overall apparent activation energy estimated from experimental data indicates that the reduction is not chemical kinetics controlled. A kinetic model has been developed to quantify the temporal evolution of different iron oxide phases and metallic iron. The ratedependent parameters (frequency factors and activation energy) have been estimated from experimental data by applying an optimization tool (Genetic Algorithm). The predicted phases at various degrees of reduction were verified by Xray diffraction and metallographic investigation. A simplified thermal model has also been developed to show the role of heat transfer on the kinetics of the reduction process under inert atmosphere. The reduction kinetics of the composite pellets in the packed bed under reactive atmosphere is not heat transfer controlled and might possibly be controlled by COgas mass transfer through the pellets.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
