Reduction of Iron Ore Pellets in a Packed Bed Reactor
Application ID: 125021
This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a porous Fe matrix and producing CO2 gas. The gas phase transport through the bed is modeled using Darcy's Law. The reduction mechanism is defined in a Chemistry interface including both a surface reaction for the FeO reduction and a gas phase reaction occuring in the reduced pellet part. The Shrinking Core Model is enabled in the Pellets subnode of the Packed Bed feature in the included Transport of Diluted Species interface.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
