Definitions

  • the invention relates to a method and a container for storing gases.
  • gases such as hydrogen, helium, argon, nitrogen, oxygen or hydrocarbons in compressed form under pressure in containers such as transportable compressed gas cylinders or permanently installed compressed gas tanks. If necessary, the gases can be removed from these containers via appropriate valves and compressed gas lines and used for industrial purposes.
  • the filling capacity of the compressed gas containers is essentially limited by two factors: (a) the size of the container and (b) the filling pressure.
  • the principle applies: the higher the filling pressure, the more compressed the gas, the greater the filling capacity.
  • An increase in the size of the compressed gas tank is associated with costly investments and takes up additional space.
  • the filling pressure cannot be increased arbitrarily.
  • existing gas pressure vessels are only designed for pressures up to approximately 200 bar. Containers that withstand higher pressures (high-pressure containers) require correspondingly thicker walls and special valves and are therefore much more expensive than the common compressed gas cylinders.
  • the invention has for its object to provide a method that allows space-saving storage of gases. With the same size and filling pressure of the storage container, the method should allow a higher filling capacity than existing methods. The method should also be inexpensive and can be implemented without great technical effort. In addition, existing, customary storage containers should be able to be used for the process.
  • This object is achieved according to the invention by a method for storing gases, in which a gas is filled under pressure into a container which contains at least one adsorbent. It was surprisingly found that the filling capacity of existing compressed gas containers can be increased by more than 240% by adding adsorbents. It was also surprising that the addition of adsorbents has a stabilizing effect on the expansion behavior of the gases.
  • All containers which are suitable for storing gases under pressure can be used in the method according to the invention.
  • pressure gas cylinders or tanks made of steel, iron or special alloys or plastics are used.
  • the containers should be designed so that they can withstand the filling pressure of the respective gas.
  • gases that can be stored under pressure can be considered as gases. These are in particular hydrogen, helium, argon, nitrogen, oxygen and hydrocarbons such as alkanes or olefins. Mixtures of different gases can also be used. The purity of the gases is not important. All substances can be used as adsorbents which, due to their surface, are capable of selectively enriching (adsorbing) gases or liquids at their interface. In particular, porous substances or substances with pitted surfaces come into consideration, such as activated carbons, aluminum oxides, silica gels, carbon blacks and aluminosilicates such as zeolites and molecular sieves.
  • the adsorbents preferably have the largest possible specific surface area (inner surface). This is preferably at least 300 m 2 / g. According to a particularly preferred embodiment of the invention, the adsorbent has a specific surface area of 300 to 1800 m 2 / g, in particular 600 to 1500 m / g.
  • adsorbent depends crucially on the gas to be stored. Practically all types of adsorbents are suitable for inert gases such as nitrogen, argon, hydrogen and hydrocarbons (eg olefins). In the case of chemically reactive gases, however, an adsorbent must be chosen which is inert to the gas. In the case of oxygen, for example, activated carbon should not be chosen as the adsorbent, since it reacts with oxygen. However, aluminosilicates such as zeolites or molecular sieves are particularly suitable for oxygen.
  • the activated carbons used according to the invention preferably have a specific surface area of 500 to 1500 m 2 / g, in particular 700 to 1300 m 2 / g. Activated carbon is particularly suitable for gaseous hydrocarbons.
  • aluminum silicates are used as adsorbents. These are characterized by high chemical inertness and.
  • the aluminum silicates which can be used according to the invention include, in particular, zeolites, feldspar, feldspar representatives, phyllosilicates, inosilicates, andalusite, sillimanite, cyanite and mullite.
  • Natural or synthetic zeolites with pore sizes of 1 to 15 angstroms, in particular 7 to 12 angstroms, are particularly suitable.
  • Suitable synthetic zeolites are, for example, those of type A, type X, type Y and type L as well as zeolite ZSM-5 and synthetic mordenite. Because of their inertness, zeolites can be used in conjunction with a variety of gases, particularly for argon, oxygen, nitrogen and noble gases.
  • the adsorbent is preferably filled into the storage container through the gas inlet opening.
  • the amount of the adsorbent to be filled depends on the type of adsorbent and gas to be stored, on the size of the container and on the intended filling capacity. However, it has proven expedient to use about 500 to 1000 kg, preferably about 700 to 900 kg, of adsorbent per m 3 of container inner volume.
  • the container provided with adsorbent is filled with gas under pressure in a conventional compressed gas filling system.
  • the gas is already adsorbed by the adsorbent during the filling process.
  • the filling pressure depends essentially on the gas to be stored and is preferably 0.1 to 150 bar. According to a particularly preferred embodiment of the invention, the filling pressure in the container is 0.1 to 60 bar, in particular 1 to 35 bar. at The process according to the invention leads to a particularly strong increase in the filling capacity of these filling pressures.
  • the adsorbent is preferably fastened in the container with suitable measures. This can be done, for example, in that the adsorbent is bounded by a sieve or a gas-permeable membrane attached to the container.
  • the container After filling, the container is closed gas-tight.
  • the gas is removed from the container in a known manner and with customary devices, for example via a sampling valve and pressure lines.
  • the invention further relates to a container for storing gases, which contains at least one gas under pressure and at least one adsorbent.
  • a commercially available compressed gas cylinder (filling volume 40 dm; max. Filling pressure 150 bar) was filled with 30 kg adsorbent (molecular sieve type UOP-PSA O2 HP; grain size 1.7-2.4 mm; pore size 10 angstroms, density 680 kg / m 3 ) filled.
  • the adsorbent was attached to the bottom of the pressure gas cylinder so that the individual grains were protected against slipping against each other.
  • the compressed gas cylinder was then filled with the following gases at a temperature of 20 to 22 ° C in a gas filling system at various pressures (0 to 150 bar):
  • Nitrogen chlorine content 10 ppm; dew point -65 ° C
  • oxygen purity 99.5%; dew point -65 ° C
  • the compressed gas cylinder was closed and provided with a removal valve.
  • Compressed gas cylinders reached filling quantities for the gases argon, nitrogen and oxygen.
  • Table 1 also shows the filling quantities achieved by the standard filling method (without adsorbent) in the same compressed gas container under the same conditions.
  • Table 2 shows the absolute amount of gas in the compressed gas cylinder filled with adsorbent (molecular sieve) as a function of the filling pressure.
  • Table 2 and FIG. 2 show that the method according to the invention leads to a considerable improvement in efficiency (relatively large amount of gas at lower pressure), especially at relatively low filling pressures ( ⁇ 40 bar).
  • Table 3 shows the filling capacities achieved by the process according to the invention at various pressures, expressed in% of the filling quantity achieved by the conventional filling process (without adsorbent) under the same conditions.
  • Table 3 and FIG. 3 show that the process according to the invention leads, in particular at pressures ⁇ 80 bar, to a considerable increase in the filling capacity compared to the conventional filling process (without adsorbent).
  • the filling capacity is increased by 200% at a pressure of 28 bar compared to the conventional filling method (without adsorbent).
  • Table 4 and FIG. 4 show specific filling capacities, based on 1 kg of the adsorbent used. All gases were filled using the procedure described under (a) (i.e. adding molecular sieve as adsorbent).
  • the extraction valve of the gas cylinder filled with gas was opened and the pressure drop in the gas cylinder and the speed of the escaping gas were monitored.
  • the gases filled according to the process described in (a) had excellent deodorization behavior. Compared to the gases filled using the conventional method (i.e. without adsorbent), they were characterized by a particularly stable and uniform gas expansion.
  • the examples show that the filling capacity of a pressure gas cylinder can be increased considerably by adding adsorbents.
  • the addition of adsorbents also has a stabilizing effect on the expansion of the gas.
