Coaxial Gas Storage System by Compression and Adsorption

Abstract

A gas storage system by compression and adsorption is useful in the field of fuels, in particular for storing and transporting gas. The present invention optimises gas storage operations by utilizing the energy obtained by the combination of the effects of simultaneous adsorption and desorption in a new gas storage system by compression and adsorption comprising two concentric reservoirs containing identical charges of activated carbon. The present gas charging and discharging system does not use auxiliary means, such as external sources, and has an increased thermal stability in a reasonable pressure range, i.e. it is more efficient and makes new storage cycles without external processing possible, reducing operating costs in comparison with the prior art.
