It is found that the Hardgrove grindability increases with increase in total carbon content C and aro- matic carbon content C , as well as the unsaturation δ of the structure. Correspondingly, the Hardgrove ar grindability decreases with increase in the volatile matter and decrease in the vitrinite ref lection coefficient due to increase in the aliphatic carbon content and http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals
