6 Study for the strength of cokes from the view points of Chemical structural analysis for Coals using solid state NMR

Abstract

Chemical structure analysis of coals is very difficult because of mixture components. But recent solid state NMR has great possibility to analyze chemical structure because of progress of pulse techniques. We have studied quantitative analysis using new pulse sequence and clarified the strength of cokes from the view points of Chemical structural analysis for Coals using solid state NMR These recent solid state NMR techniques are very powerful and useful in order to clarify both the chemical structure and functions of coals.
