Modeling of coal swelling induced by water vapor adsorption

Zhejun PAN

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1,   Pages 94-103 doi: 10.1007/s11705-011-1172-2

Abstract: Gas adsorption-induced coal swelling is a well-know phenomenon.Coal swelling or shrinkage by adsorption or desorption of water vapor has not been well understood butUnlike gas adsorption in coal which usually forms a single layer of adsorbed molecules, water vapor adsorptionThe model extended an energy balance approach for gas adsorption-induced coal swelling to water vaporadsorption changes the surface energy, which thus causes coal to swell.
