Coal Blending an overview ScienceDirect Topics

Many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. For example, Jo (1965) considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component (coal rank) and the addition of a suitable amount of caking component (caking property)
