Contribution à l'étude du stockage du méthane par adsorption

Abstract : Natural gas, which methane is the main component, is an alternative fuel. It is abundant and has clean burning characteristics; however its storage is difficult due to its very low density. Two storage routes were investigated. Methane adsorption was studied in optimized microporous carbons. They were prepared by chemical activation of anthracite powders with sodium hydroxide, and were then compacted. Associating both high adsorptive capacities and high apparent densities finally allowed exceeding the target of 150 volumes of methane delivered per volume of storage vessel at 20°C and 3.5 MPa. Formation of methane hydrates was also observed in micro mésoporous carbons, at 2°C and at pressures higher than 4 MPa.
