Goonyella coking coal was extracted with tetrahydrofuran (THF), chloroform, N-methyl-2-apyrrolidinone (NMP), pyridine, and a 1:1 (v/v) carbon disulfide/N-methyl-2-pyrrolidinone (CS2/NMP) mixed solvent. Temperature-variable dynamic viscoelastic measurement was carried out for the extracts and residues obtained. The thermoplasticity in residues obtained by chloroform or NMP extractions significantly decreased compared to that of the raw coal despite the fact that the extraction yields, 2.7 and 5.4 wt % (daf), respectively, were low. A further decrease in thermoplasticity was observed for residues obtained in high yield with pyridine (20.6 wt %) and CS2/NMP (42.8 wt %). On the other hand, the thermoplastic state was observed in the range 260-500 degreesC for the pyridine soluble (Sox-PS) fraction obtained from pyridine Soxhlet extraction, while the thermoplasticity for the pyridine insoluble fraction (PIMS) obtained from pyridine fractionation of the CS2/NMP extract fraction was significantly smaller and similar in value to that for residues left after chloroform or NMP extractions, despite the fact that the PIMS originally was a component of a solvent-soluble fraction. The role of solvent-soluble components on the thermoplasticity of coals is discussed based on these results and results of an earlier study.
