Abstract: A method and system for filling gas storage vessels from a source operates by cooling a sorbent, opening a valve to transfer gas by physisorption, regulating the sorbent temperature to achieve the desired degree of filling, closing the valve connecting to the gas source, and warming the tank, sorbent, and gas to provide a predetermined pressure at room temperature.
Abstract: Solid sorbents, systems, and methods for pumping, storage, and purification of gases are disclosed. They derive from the dynamics of porous and free convection for specific gas/sorbent combinations and use space filling polyhedral microliths with facial aplanarities to produce sorbent arrays with interpenetrating interstitial manifolds of voids.
