Sorption Investigations of Methane on Coal

摘要

Desorption work was conducted on fine coal particles at near atmospheric pressure. An apparatus has been developed that uses a capacitance manometer desorption of methane from coal particles up to 2 inches in diameter and pressures up to 1,000 psi. This will make it possible to duplicate the desorption process as it occurs in its natural underground environment. (Author)
