Methane adsorption on various adsorbents and the possibility of its storage in the adsorbed state

Abstract

The adsorption of methane on MN 200 and MN 270 polymer adsorbents, and on active carbon D4609, is investigated in the pressure range of 0.1-40 MPa at temperatures of 303, 323, 343, 373 K. Adsorp tion volumes are determined for these adsorption systems, and the isosteric heats of adsorption are calculated. Based on our investigations, we consider the possibility of storing methane in the adsorbed state in containers and the efficiency of the approach relative to gas storage in containers without adsorbents. Recommendations on selecting an adsorbent for methane storage are given, and one possible way of increasing the amount of stored gas is described.
