Measurement of Adsorption of Methane at High Pressures for Alternative Energy Systems

Resumo

A technique for the measurement of the equilibrium absolute adsorption of gases, in particular, of natural gas (methane), at pressures up to 10 MPa, is proposed. A plant for use in performing the measurements by means of a volumetric method is described. Estimators of the measurement errors are presented. Adsorption isotherms of methane by AU-1Sh miroporous carbon matter in the range of pressures 10^–7–10 MPa and temperatures in the range 178–360 K are obtained by means of the proposed technique.
