  • Patent number: 9322510
    Abstract: Described is a method of charging a sorption store with a gas. The sorption store comprises a closed container and a feed device which has a passage through the container wall, through which the gas can flow into the container, and the container has at least two parallel, channel-shaped subchambers which are located in its interior and are each at least partly filled with an adsorption medium and whose channel walls are coolable. The method comprises, in a first step, feeding in a gas in such an amount that a pressure in the store of at least 30% of a predetermined final pressure is reached as quickly as possible and, in a second step, subsequently varying the amount of gas fed in in such a way that the course of the pressure in the store approximates the adsorption kinetics of the adsorption medium until the predetermined final pressure in the store is reached after a predetermined period of time.

  • Patent number: 9273829
    Abstract: Describes is a sorption store for storing gaseous substances. The sorption store for storing gaseous substances comprises a closed tank and a feeding device, which comprises a passage through the tank wall, through which a gas can flow into the tank. The tank has inside it at least one separating element, which is configured in such a way that the interior of the tank is divided into at least one pair of channels comprising two parallel running channel-shaped compartments, the ends of which are in connection with one another in each case by way of a common space, each channel-shaped compartment being filled at least partially with an adsorption medium. The feeding device is designed in such a way that inflowing gas is diverted almost exclusively into one of the two compartments of each pair of channels.
