Coking Coal

Coking Coal

Research on coke making seeks to take advantage of insights that may help to reduce the proportion of prime coking coals utilised in coke blends and to expand the range of coals that could be used in these operations (Sasaki et al. 1998). Shifting the coke blend composition toward weakly coking coals is therefore commercially attractive.

Coal rank is a prevalent feature in both coke quality prediction models and coal blending decisions, particularly in the form of the mean maximum vitrinite reflectance (R v,max; North et al. 2018b). This prevalence is likely due to the relationship between coal rank and other key coal properties such as fluidity (Coin and Broome 1997 ; Ryan et al. 1998 ).
