A 2 g sample of coal, before sorption measurement, was subjected to a degassing process to clean the coal surface of adsorbed vapours and gases. The sample was placed in a helium atmosphere for 24 h before degassing. Helium atoms do not sorb, and their kinetic energy allows the removal of sorbed gases from the coal surface.
