Microstructure characterisation for evaluation of coke quality
Abstract
It is important to have accurate indicators of coke quality, relating to its strength and reactivity, in order to ensure that coke is suitable for its purpose. Factors that can affect the quality of coke include the properties of the original coal and the operational details of the carbonisation process.The resulting coke is a porous composite material which has a complicated microstructure, and the coke quality is related to the properties of its microstructure. Here we use a micro-CT scanner to create high resolution 3D images of coke microstructure, perform 3D image analysis and finite element analysis (FEA) to determine the fundamental properties of the coke and relate them to the standard industry measures of coke quality. Two types of FEA were considered – linear elasticity, which gives indicators of coke strength and diffusion, which gives an indicator of gas transport in the pores.The results show that measured abrasive coke strength indices show a reasonable correlation with the elasticity results, while the relationship between gas diffusion and coke reactivity is more complicated.
