Important structural features in coals and their relationship to coal reactivity

摘要

High resolution mass spectrometry was used to analyze 8 Argonne premium coal samples. The most important heteroatom in coals is oxygen. There is a trend of increasing percentage of furans and ethers with rank. Influence of furans plus ethers are important and constant across all ranks for vitrinite rich coals. Strong bond cleavage may be more important than previously thought; this has strong implications for the choice of model systems for coal thermolysis.
