Methane equilibrium adsorption isotherms were determined for several U.S. coal seams--Illinois No. 6 (Herrin seam), Oklahoma Hartshorne, Pennsylvania Pittsburgh, and Virginia Pocahontas No. 3 Seams--using a volumetric method and an equation of state for methane. The amount of methane adsorbed on crushed and dried coal was measured as a function of pressure. Isotherms were measured at 30 deg. C for the Illinois coal and at 0 deg., 30 Deg. and 50 deg. C for the others. Most measurements were made to 150 atm pressure, but a few were made to 240 atm.
