✦ Synopsis

Results are presented of a study of the distribution of pore volume and surface in micropores of coal from adsorption equilibria of methanol vapours at temperatures ranging between 293 and 343 K according to a new method. Typical parameters of the micropore: structure of twenty samples of coals of carbon contents between 64 and 91% are calculated for a model of cylindrical pores. The micropore surface areas are compared with the results obtained by using the DKR and BET equations, and with already published kata from small-angle X-ray scattering. The agreement between results is satisfactory, This evidence suggests that the use of the new method of evaluating the basic parameters of the microstructure can be recommended.
