Carbon disulfide-N-methyl-2-pyrrolidinone (NMP) mixed solvent (1:1 by volume) has been found to give high extraction yields (40-80wt%, daf) for many bituminous coals at room temperature. The extracts obtained were fractionated with acetone and pyridine, into acetone soluble (AS), acetone insoluble, pyridine soluble (PS) and pyridine insoluble (PI) fractions, respectively. The part of PI fraction was found to become insoluble in the CS_2-NMP mixed solvent. The increase of the solubility of PI fraction by the addition of the compounds such as TCNQ, TCNE and p-phenylenediamine suggests that this insolubilization behavior may be ascribed to the association of PI fraction by non-covalent interactions. The nature of the non-covalent interactions will be discussed.

In the course of studies on estimation of unit chemical structure of Akabira coal, the following points were suggested to be studied further: (1) molecular weight of extracts (2) chemical bonds linking aromatic clusters. As for molecular weight, light scattering method was employed to measure the M.W. of extracts and hydrogenation of extract was carried out under very mild conditions. This light scattering method was found not to be suitable for this kind of samples. GPC evaluated the M.W. of extracts to be Mn 418, Mw 903, and Mz 1620. As for chemical bonds, catalytically cracking of the coal was carried out under D_2 atmosphere, the results indicating that aliphatic long chain exists as free, linked with aromatic rings and inserted between aromatic rings. Based on the present results, the authors could refine the concept of previously proposed model structure concerning Akabira coal.

We have reported that there are considerable amounts of extractable substances existing in some bituminous raw coals on the basis of extraction yields (more than 50wt%, daf) of the coals with carbon disulfide-N-methyl-2-pyrrolidinone mixed solvent at room temperature. The swelling ratios of the extraction residues with the mixed solvent increased with the increase of the extraction yield. Size exclusion chromatography using columns packed with the residues showed that the residues had an ability to separate polystyrene standard samples with various molecular weights. From these results the cross-link structure of bituminous coals will be discussed.

Coprocessing of Wandoan or Akabira coal with Athabasca oil sand bitumen was carried out over coal liquefaction catalyst (ex: NiCl_2-LiCl-KCl) and/or upgrading catalyst of heavy oil (ex: Ni-Mo/Al_2O_3). The highest oil yield and the highest conversion to benzene soluble materials were attained when the two catalysts were used together.
