A one-dimensional model has been developed for the simultaneous drying and combustion of a semi-infinite wet coal slab. The model takes into account the vaporization of coal moisture and the existence of a moving evaporation front, pyrolysis and char/gas reactions occurring in the dry coal zone, Dar

In a study of the enlargement of pores of coals it has been found that treatment of a bituminous coal (PSOC No. 371, from the Pennsylvania State University Coal Section) with a 5:95 O,:N, stream 4 h at 400°C increases the surface area as measured by nitrogen adsorption at 77K by a factor of at least
