Experimental kinetic data for three Australian coals are compared with predictions from the mathematical model developed in Part I. For these coals, as well as data reported for North American coals, the model is found to show good agreement, using the characteristic molecular weight as the only par

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 form. Results are interpreted in terms of the effects of briquetting on pore structure.
