Definitions
- the invention relates to a device for gas separation, particularly for the separation of N 2/0 2, CO 2 / H 2 and N 2 / CO mixtures Gasmi ⁇ 2. Furthermore, the invention relates to a method for producing such a device.
- membranes A distinction is made between so-called mesoporous membranes, ie those with pore diameters between 2 and 50 nm, and microporous membranes which have pores with a pore diameter of less than 2 nm.
- microporous membranes eg. As silica membranes, known from the literature.
- the separation of the gases is based on the principle of molecular sieving, whereby a first gas from the gas mixture can pass through the membrane, but not another because of the larger kinetic molecular diameter.
- the driving force for the separation process is the pressure difference between the two gas spaces.
- the most important characteristics of gas separation membranes are their permeability and separation factors. These properties give the separation performance and the membrane requirements for a separation task.
- a flow J (unit: kg m "2 s ' 1 ) sets in at steady-state conditions under the driving force of a partial pressure difference for a particle through a membrane piece with the area A.
- the permeability P of a membrane is normalized as a gas flow per membrane area, time and partial pressure difference for the permeating gas indicated (unit: Nm 3 (STP) m "2 h “ 1 bar “1 , STP: O 0 C, 101325 Pa, 22.414 1 Molvolu ⁇ men).
- the separation efficiency of a membrane material is indicated by the separation factor ⁇ .
- the separation factor for a gas pair is defined as the ratio of the gas permeabilities P. It depends on the temperature, the feed pressure and the pressure difference across the membrane as well as the pore diameter and the pore distribution. Separation factors are approximately not dependent on the membrane thickness. Exceptions are membranes with very thin separation layers ( ⁇ 0.1 ⁇ m) compared to isotropic films (100 ⁇ m).
- Gas permeation separates gas streams into streams of different components. As established industrial applications, it has the separation of hydrogen from the process gas, the nitrogen / oxygen separation from air and the recovery of organic vapors such as, for example, gasoline vapors from gas / air mixtures.
- microporous membranes such as multilayer silica membranes (amorphous SiO 2 ), zeolite membranes or carbon membranes, as well as metal membranes (eg PdAg alloy) or perovskite membranes as mixed-conducting dense membranes.
- metal membranes eg PdAg alloy
- perovskite membranes as mixed-conducting dense membranes.
- Their fields of application are versatile and different. They have in common their applicability under difficult process conditions, such as, for example, high temperature and / or high pressure.
- the typical applications of gas permeation with inorganic membranes are, in particular, the necessary purification of gas streams with regard to subsequent process steps (eg risk of catalyst poisoning), the shift of the reaction equilibrium by selective separation of products or by-products and the concentration of product streams to reduce the energy requirement subsequent finishing steps.
- Membrane systems often have a modular design and can therefore be adapted variably to different problems. Fer ⁇ ner can be driven in a simple manner different throughputs. They do without moving parts and are usually relatively lightweight and compact.
- IKTS Fraunhofer Institute for Ceramic Technologies and Sintered Materials
- Ceramic filtration membranes for liquid filtration and gas separation are produced by, in part, multiple applications of thin layers each of finer porosity on a coarsely porous substrate. Such membranes are also called asymmetric membranes.
- Typical substrates are tubes or multi-channel elements. In the case of disks as substrates, the so-called flat membranes are obtained.
- IKTS Sintered Materials
- polymer membranes with layer thicknesses adjustable between 1 and 5 ⁇ m which are produced by coating the substrate with a specially prepared silicon-organic precursor and subsequent polymer pyrolysis.
- a precursor system gives, for example, a pore diameter of about 1.5 nm with a low distribution and BET surface areas of up to 600 m 2 / g.
- the pyrolysis of other polymer classes leads, depending on the molecular structure and the thermolysis conditions. different pore diameters between 4 and 20 nm with a narrow pore size distribution.
- polymer membranes are currently being developed for the separation in the low temperature range.
- Exist for applications at higher temperatures up to 500 0 C for example, water-serstoffpermeable AgPd membranes and amorphous microporous silica membranes.
- dense ionic, mixed or proton conductors are also under discussion.
- the chemical processes generally have a high loss of efficiency, while the polymer membranes are limited to applications at low temperatures.
- the maximum Einsharmalia for expensive AgPd membranes and silica membranes is about 500 0 C.
- the disadvantage react these membranes also sensitive to water.
- the object of the invention is to provide a device with which a gas separation of technically relevant gases, such as, for example, H 2 , N 2 , O 2 or CO 2 from a gas mixture, is possible, especially at higher temperatures. Furthermore, it is the object of the invention to provide a method for producing such a device.
- the objects of the invention are achieved by a device with all the features according to the main claim, and by methods with the entirety of features according to the independent claims. Advantageous embodiments of the method and the device can be found in the respective dependent claims.

- it can be made of a steel, for. B. 316 L stainless steel and / or a ceramic.
- the thickness of the carrier layer is dependent on the separation protolem, and may vary between 100 ⁇ m and 1 mm.
- the thickness of the carrier layer influences the degree of permeation, and should therefore be configured in principle as thin as possible, in particular smaller than 1 mm.
- layer thicknesses of at least 100 ⁇ m, better 200 ⁇ m are desirable.
- metallic carrier layers generally have a better stability than ceramic layers with a comparable layer thickness.

The determination of these average pore diameters can be carried out in particular by SEM (scanning electron microscopy) or with smaller pore diameters via TEM (transmission electron microscopy). The pores are markedly larger than those of the adjoining func- tion layer.
- the carrier layer should be used for mechanical stabilization. care, but if possible, avoid any flow resistance.
- a functional layer is arranged which has an average pore diameter as a function of the separation problem to be solved of less than 1 nm, in particular less than 0.8 nm and particularly preferably Partly less than 0.5 nm.
- the functional layer causes the actual separation of the gas molecules. Theoretically, the average pore diameter should be between those of the gas molecules to be separated. However, it has been shown that even slightly larger pore diameters lead to a very good degree of separation.
- the functional layer comprises in particular TiO 2 or ZrO 2 and can be made particularly thin. advantageous
- Layer thickness are in the range of a few to a few hundred nm.
- the embodiment depends on the separation problem and the separation performance to be achieved.
- the selectivity increases regularly with decreasing pore diameter of the functional layer.

- the intermediate layer is likewise porous throughout.
- the average pore diameter of the intermediate layer is advantageously between that of the carrier layer and that of the functional layer, in particular between 2 and 100 nm.
- the intermediate layer advantageously has a layer thickness in the range between 100 nm and 50 ⁇ m.
- a functional layer is disposed on both sides of the carrier layer.
- the symmetrical arrangement is to be selected in particular when the individual layers are made very thin, since then the bilateral, symmetrical arrangement advantageously leads to an additional stability of the separation device.
- the symmetrical structure minimizes distortion during the sintering process.
- the functional layer if appropriate together with an intermediate layer, is present as a graded layer.
- the properties of the abovementioned intermediate layer are then present in particular at the boundary layer carrier layer / graded layer, while the properties of the abovementioned functional layer are present in particular on the free surface of the layer system. This means that the average pore diameter from the carrier layer to the free surface gas / functional layer decreases in principle continuously or else in a stepped manner.
- a layer with coarser pores on the outer functional layer with a very small pore diameter for stability reasons.
- a porous ke ⁇ ramische or metallic foil with a layer thickness zwi ⁇ rule 200- 500 microns thickness is provided as the support layer first.

- the functional layer required for the actual gas separation can advantageously be applied by means of a sol-gel method.
- CVD chemical vapor deposition
- PVD physical vapor deposition
