Abstract:A low‐rank coal is examined for swelling in benzene–pyridine and toluene–pyridine mixtures. In each case, swelling is shown to mainly due to the pyridine, the action of which is specific and not amenable to interpretation by the solubility parameter approach to understanding coal swelling.
The swelling of a low‐rank coal under the influence of various solvents is examined and results compared with those for a similar coal in briquetted from. Results are interpreted in terms of the effects of briquetting on pore structure.
