Abstract:
Many coals have the peculiar property that when heated they melt and resolidify to form a hard, strong coke. This thermoplastic behaviour of coals is industrially important but poorly understood.

I will talk about the nature of this phenomenon, what affects it and what that tells us about coal structure. For example, it was recently found that many coals interact when their blends are heated in a way that affects their thermoplastic behaviour. These interactions are mediated by transfer of volatile material between the coals on heating.
