✦ Synopsis

Swelling of hvB coal by vapour of the solvents pyridine, tetrahedrofuran, dimethylformamide and methanol was carried out. Vapour-saturated coals were extracted using selected solvents and extract yields for swollen and fresh coals were compared. It is found that some solvents can block pathways to some, but not all, sites that were accessible to other solvents when they were interacting singly with fresh coal.

In this paper the solvent swelling technique is applied to coal residues obtained by catalytic hydrogenation, to monitor the changes produced in crosslinking density during the hydrogenation process. An attempt is made to correlate the volumetric swelling ratio with coal rank, temperature and reside
