Selected minerals were added to an industrial coal blend and coked to determine whether elements in different mineral forms change coke properties. Mineralogy can influence dilatation, fluidity, coke texture, and catalyze gasification reactions of carbon at
1100°C and 1500°C.
This report discusses some of the findings of CANMET studies to assess Canadian coking coal quality and their use in newer cokemaking technologies. The use of Canadian coking coals in commercial types of coal blends has been investigated and the results have been
good. Empirical predictions of the coke quality for individual Canadian coals, based on laboratory scale results, have been shown to be often limited, particularly for methods developed in other countries. The definitive coal evaluation meth -od for Canadian coals remains pilot-scale coke oven
testing. Cleaning of given western Canadian coking coals to different mineral matter (e.g. ash) levels changed the resulting coke quality. An example is given that can be explained by changes in the petrographic composition of the coal, but the influence of other factors such as coarser sized
mineral matter is still under investigation. Canadian coals were effectively used in studies of new coking technologies such as partial briquetting, preheating and pitch additions. It is concluded that Canadian coking coals can be excellent coking blend components or most satisfactorily used in new
coking technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
