8.石炭の高温NMR測定と軟化溶融状態

抄録

In-situ high temperature NMR measurement was applied to evaluate thermoplasticity of coal. Detailed analysis of FID signal obtained from 25 to 570℃ for coal and coal model (mixture of coke breeze and pitch) revealed that the plastic stage was considered to be composed of three components, a liquid-like component, a solid-like component and another liquid-like component which has low mobility through some interaction with solid-like component. The parameters obtained by high temperature NMR are expected to be useful for characterization of coal thermoplasticity.
