✦ Synopsis
For four Kentucky coals, a comparison was made between pore volume distribution evaluated from CO2 adsorption isotherms calculated from the Cranston-lnkley method and the Medek method. These distributions agree in the micropore range from approximately 0.6-2.0 nm. Most of the pore structure is in the micropore range. For the mercury penetration studies a rectilinear relation is found between penetrated volume and applied pressure from approximately 0.1 MPa (1 atm) up to 345 MPa (3400 atm). Surface areas were calculated from adsorption data by the BET, Langmuir, and Dubinin-Polanyi methods.
