چکیده:

A non-isothermal transient model has been developed to simulate the reduction process and thermal behaviors of a porous wustite pellet undergoing chemical reactions with amixture of hydrogen, carbon monoxide, water vapor and carbon dioxide which is commonly named Syngas. The model describes the chemical reaction itself, the massbalance for each gaseous species and the energy equation within the pellet. For solution ofthe governing equations, a Computational Fluid Dynamic (CFD) approach as a fullyimplicit formulation of Finite Volume Method has been applied. The model has then beenvalidated by comparing with experimental data from literature. Eventually the effects of Syngas and pellet characteristics, as composition, bulk temperature, pellet porosity andpellet diameter, have been investigated on the overall reduction degree of wustite pellet.
