Both methane and helium flow through solid coal by Knudsen diffusion, even at relatively high pressures. Knudsen permeabilities were determined for samples of Pittsburgh, Pocahontas No.3, and Oklahoma Hartshorne coals. The average permeability for dry methane was I.3 X 10e6 cm2/s for Pittsburgh coal

Diffusion of methane from threecoals ranging in rank from anthracite to HVA bituminous has been studied at initial methane pressures up to about 2.76 MPa (400 psi). Unsteadystate diffusion conditions existed, the methane pressure within the coal particle decreasing with time while the methane pressu
The dependence on moisture content of the methane sorption capacity of four American coals has been investi~ted. Bjtuminous coals from Virginia, West Virginia, Oklahoma and Pennsylvania were studied at a temperature of 3O"C, and at pressures up to 60 atm. Methane capacity decreased with increasing m
## The gas chromatographic method has been used to measure the effective diffusion coefficients D, or the diffusion parameters 0,/d\*. Nitrogen was used as a carrier gas, krypton-85 as test gas. The tests were carried out on different activated carbons made from air-preoxidized bituminous coals wh
Experimental studies of methane diffusion from coal cuttings have been analysed with both a unipore diffusion model and a bi-disperse pore structure diffusion model to determine the time range of each model's validity. Initial desorption, during the first 50% of volume desorbed, can be adequately de
