Abstract
The effects of chlorobenzene and other non-polar solvent treatments on
liquefaction behaviour are extremely varied and depend both upon the coal and
liquefaction regime used. The treatments give rise to significant, but non-uniform,
conformational changes in the macromolecular structure of bituminous coals.
Solvent swelling, NMR and vitrinite reflectance measurements have indicated that
the increase in microporosity is accompanied by the formation of additional
hydrogen-bonds, with aromatic moieties possibly being less ordered.
