Definitions

  • the invention relates to a method for storing a gaseous medium with the features of the preamble of claim 1. Furthermore, the invention relates to a storage tank for a gaseous medium having the features of the preamble of the independent apparatus claim 1.
  • a method and a storage tank having the features of the preambles of the two independent claims are known from WO 2007/074098 A1 of the applicant.
  • storage tanks are usually used to store gaseous media in a storage tank in a vehicle, which makes it possible to store the gaseous medium (for example hydrogen or natural gas) under a pressure of several 100 bar.
  • gaseous medium for example hydrogen or natural gas
  • the use of such storage tanks designed for the corresponding pressures has the consequence that they have to be specially constructed for safety reasons or have a very high strength.
  • MOF metal organic framework
  • This Material is characterized by the fact that the gas molecules are stored or absorbed in cavities of the MOF material.
  • This technology makes it possible in particular to reduce the pressure of the storage tank from the above-mentioned several hundred bars to typically a maximum of about 70 bars for the same storage volume of the gaseous medium in the storage tank.
  • the inventive method for storing a gaseous medium with the features of claim 1 and the storage medium for the gaseous medium according to the invention with the features of the independent device claim has the advantage that it in a surprising manner using a relatively small amount of MOF material allows relatively large amounts of gaseous medium to be stored in the storage tank.
  • the invention is based on the idea that, in contrast to the commonly used technology, in which the MOF material or its particles are compressed, they do not compress or form as fine-grained as possible, so that a maximum surface area per particle of the MOF material Connection of the gas molecules of the gaseous medium is available.
  • the MOF material is arranged in the form of loose, freely moving particles in the storage tank, so that the MOF particles in the introduction of the gaseous medium in the Storage medium are flowed around by the medium, wherein the gas molecules of the medium are bound by the MOF material or the MOF particles.
  • the teaching of the invention provides that the MOF material is arranged in the form of loose, freely movable MOF particles in a subspace of the storage tank between the inlet and the outlet.
  • a particularly preferred method provides that the MOF particles are disposed within the storage tank in a partial space which is limited in the direction of a (gas) outlet of a non-passable for the MOF particles barrier element, and that the gas molecules, the blocking element when opening of the outlet in the direction of the outlet.
  • a method ensures that no MOF particles are eliminated from the area of the storage tank and, if necessary, can damage equipment that is operated with the gaseous medium.
  • avoiding loss of material from MOF particles allows for a high storage capacity over the entire lifetime or operating life of a storage tank.
  • the pressure in the storage tank is a maximum of 70 bar.
  • Such a relatively low overpressure suffices in the conventional dimensioning of such storage tanks in a vehicle for storing comparable amounts of gaseous medium as in a high-pressure tank in which there are more than 100 bar pressure.
  • such a low storage pressure also makes it possible for the storage tank to be manufactured relatively simply or with a low wall thickness and with conventional materials with a low weight.
  • the gaseous medium is preferably used for operating a vehicle by means of a fuel cell system or an internal combustion engine.
  • the subspace in which the MOF particles are arranged is arranged between an inlet and the outlet for the gaseous medium, and that the entire cross section of the subspace can be traversed by the gaseous medium.
  • a preferred embodiment of the storage tank therefore provides that the storage tank is arranged in operative connection with a heat exchanger.
  • a heat exchanger it is possible to provide the energy obtained in the heat exchanger for further applications.
  • the storage tank 10 shown in the single figure is used to store a gaseous medium 1 with symbolically represented gas bubbles.
  • the gaseous medium 1 is, for example, hydrogen or natural gas.
  • the hydrogen or natural gas is used to operate a fuel cell system or an internal combustion engine, not shown, of the vehicle.
  • the storage tank 10 which consists, for example, in a conventional manner of metal, has an inlet 12 having an inlet valve and an outlet 14 for the medium 1 which is delimited by a check valve (not illustrated), wherein the inlet 12 and the outlet 14 are preferably connected to one another. overlying end portions of the storage tank 10 are arranged. Via the inlet 12, medium 1 under pressure is introduced into the storage tank 10, while via the outlet 14 the medium 1 of the fuel cell system or the internal combustion engine can be fed.
  • a partial space 18 is formed, in which MOF (metallic organic framework) particles 2 are arranged for absorption or storage of the medium 1.
  • the subspace 18 is selected to be so large that the MOF particles 2 are arranged loosely and with free spaces between the MOF particles 2 in the subspace 18.
  • the partial space 18 is delimited in the direction of the inlet 12 by a blocking element 20, for example in the form of a filter mesh whose pore width is such that the MOF particles 2 can not pass the blocking element 20, but the gas molecules of the medium 1 the side of the inlet 12 of the subspace 18 is limited by a gas distribution means 22, which ensures that via the inlet 12 into the storage tank 10 entering gas or medium 1 can enter evenly over the entire cross section in the subspace 18 and flows through it.
  • the storage tank 10 is arranged in operative connection with a heat exchanger 25 shown only symbolically in order to remove the heat arising during the absorption of the gas molecules of the medium 1 from the storage tank 10.
  • the medium 1 When the medium 1 is introduced into the storage tank 10, the medium 1 passes through the gas distribution means 25 and comes into operative connection with the MOF particles 2 arranged in the subspace 18 over the entire cross section of the subspace 18.
  • the gas molecules flow around the MOF particles 2 so that the absorption or connection possibilities of the MOF particles 2 for the gas molecules are maximized.
