A new approach to investigating coke reactivity
The coke analogue is a new research tool that has been developed to quantify and characterize the effect minerals in coke have on coke reactivity. The analogue material is made from a number of different carbon or carbon containing materials and minerals to in part replicate real industrial coke's reactivity behavior. Elucidation of the effects of minerals on coke reactivity has proved difficult due to the complex and heterogeneous nature of industrial coke and the potential non-additive effects of minerals on coke reactivity. The coke analogue addresses this complexity and heterogeneity through control of its mineralogy, mineral size and mineral dispersion through the analogue, porosity and carbon structures. Initial studies using the analogue were focused on coke dissolution kinetics in liquid iron but recent work has focused in characterization of its porosity, carbon structure and rate of reaction.
