NOVELTY - The sorption store comprises two gas adsorbent media disposed within a horizontally mounted vessel. The gas adsorbent media are distinguishable from each other by different adsorption capacities. The adsorption capacities are defined by the ratio of the mass of the adsorbed gas to the mass of the adsorbent medium for the stored gas at equal adsorption conditions. The adsorption conditions are defined by temperature, pressure and gas phase composition. The temperature in vessel increases in vertical direction from the bottom to the top of the vessel during and/or after the filling with gas.    USE - The sorption store is useful for the storage of a gas, in a drive system of a vehicle (all claimed) such as a car and a truck, in a drive system of a boat, and for stationary applications in gas stations, where the gas is useful for an internal combustion engine or a fuel cell.    ADVANTAGE - The sorption store compensates the limiting effect on the adsorption capacity due to an elevated temperature during filling the vessel with gas, enables rapid and efficient filling of gas, and has higher energy density.    DETAILED DESCRIPTION - The sorption store comprises two gas adsorbent media disposed within a horizontally mounted vessel. The gas adsorbent media are distinguishable from each other by different adsorption capacities. The adsorption capacities are defined by the ratio of the mass of the adsorbed gas to the mass of the adsorbent medium for the stored gas at equal adsorption conditions. The adsorption conditions are defined by temperature, pressure and gas phase composition. The temperature in the vessel increases in vertical direction from the bottom to the top of the vessel during and/or after the filling with gas. The gas adsorbent media are spatially separated from each other in a way that a first gas adsorbent medium, characterized by a greater adsorption capacity for the stored gas compared to a second gas adsorbent medium at a first temperature, is located in the vessel in vertical direction closer to the top of the vessel than the second gas adsorbent medium. The first temperature is the current average temperature of the first adsorbent medium during and/or after the filling with gas. The gas adsorbent media are spatially separated from each other by a separator, which is permeable for gas and not permeable for the adsorbent media. The gas adsorbent medium is a porous and/or microporous solid, and is present as a bed of pellets. The ratio of the permeability of the pellets to the smallest pellet diameter is 1asteriske-12 m2/m and 1asteriske-14 m2/m. The total mass of adsorbent media disposed in the vessel is more than 30 wt.% of the first adsorbent medium and less than 70 wt.% of the second adsorbent medium. The volume in the vessel, predetermined for the disposition of the second adsorbent medium, is kept free of adsorbent media and used for gas compression without adsorption. The vessel is a pressure vessel for the storage of gas at a pressure of 1-100 bar.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a sorption store.
