Effect of Mineralogy and Carbon Structure on Coke Properties ofAustralian and Chinese Coals and Their High Temperature Behaviour
The relationship between coal properties and coke thermal strength was reviewed. Several Australian and Chinese coking coal samples of differing coke strength and reactivity were selected. Coke samples from these coals were studied in conjunction with the properties of the original coals. Coal and coke samples were analysed using XRD/SIROQUANT and QEMSCAN analysis. The Study shows that mineralogy of Chinese coals is significantly different from that of Australian (Gondwana) coals of similar rank and petrology. Mineral transformation of coke at higher treatment temperatures and reacting conditions are presented. The evolution of carbon structure of Chinese and Australian cokes during heating is compared and also related to properties of the parent coals. This study demonstrates that the high temperature behaviour of cokes is significantly different from properties estimated from conventional coke quality parameters such as coke strength after reaction (CSR). This study will contribute in quantifying and optimising the role of minerals on the ultimate coke quality of blends.
