Research on coal and products from coal, including products of combustion, is becoming more concerned with environmental applications and with coal products from liquefaction, pyrolysis, and combustion.
PROXIMATE AND ULTIMATE ANALYSISRapid Methods. Samples (A2) described quick laboratory methods for determinations such as ash, moisture, sulfur, and sodium and also discussed the use of statistics. Rexin (A2) reported on methods for rapid and reliable approximation ofASTTM procedures for use in coal quality control in mining; determinations discussed included microwave air-drying, ash, sodium, and calorific values.
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.
