Definitions
- the present invention relates to catalytic membrane reactors or CMRs.
- a Membrane Catalytic Reactor is composed of a mixed conductive dense membrane (electronic and ionic) of oxygen anions. Under the action of an oxygen partial pressure gradient imposed on either side of the membrane, the oxygen anions O 2 " , coming from the air, pass through the membrane of the oxidizing surface towards the reducing surface, to react with methane on the latter
- Figure 1 illustrates the set of elementary steps in the transport of oxygen through a membrane, which are six in number:
- each of the steps described above can be a limiting step in the transport of oxygen through the membrane.
- the limiting step is the exchange of surfaces, and more particularly to the reducing surface of the membrane
- PM Geffroy et al. "Oxygen semi-permeation, oxygen diffusion and surface exchange coefficient of La (i x ) Sr x Fe (i y ) Ga y 0 3 -d perovskite membranes ", Journal of Membrane Science, (2010) 354 (1-2) p.6-13; PM Geffroy et al., "Influence of oxygen surface exchanges on oxygen semi-permeation through the (i x ) Sr x Fe (i y ) Ga y o 3 -o dense membrane” Journal of Electrochemical Society, (201 1) , 158 (8), p.
- the surface state of the membranes for the CMR application plays a major role in the performance of the process [PM Geffroy et al., "Oxygen semi-permeation, oxygen diffusion and surface exchange coefficient of the (i x ) Sr x Fe (i y.) Ga y 0 -d 3 perovskite membrane "Journal of membrane Science, (2010) 354 (1 -2) p.6-13; PM Geffroy et al., "Influence of oxygen surface exchanges on oxygen semi-permeation through the (1 x ) Sr x Fe ( 1y) Gay03-s dense membrane” Journal of Electrochemical Society, (201 1), 158 ( 8), p.
- the cohesion of the entire layer is obtained by a modification of the grains of the powder, which is reflected more particularly by their magnification. There is therefore a decrease in the density of grain boundaries.
- the current methods of synthesis of materials do not allow to obtain grains of very small diameter.
- the tortuosity in the porosity increases; this therefore reduces the useful area on which surface exchange can take place.
- One of the objects of the present invention is therefore to propose an operating protocol for obtaining a nano-structured architecture which, at high temperature, that is to say at a temperature above the crystallization temperature, is a ultra-divided perovskite composed of crystallites 10-100 nm in diameter.
- the layer of material thus formed develops a large surface area and has a high density of grain boundaries. It also has an increased microstructural stability, whether grain size or grain boundary density, at high temperature (700 ° C to 1000 ° C) and over a long period (more than 2 000h ).
- the methods generally used today to increase the exchange surface of the membranes are the deposition of a porous layer by screen printing, the use of a porous support where the porosity is created by the use of a porogenic agent and the use of mesoporous materials.
- the screen printing ink is then deposited on the membrane using a squeegee that forces the ink to pass through the screen printing mask to print the desired patterns. The deposited thickness is between 20 ⁇ and ⁇ ⁇ .
- Figure 2 is a photograph taken under a scanning electron microscope (SEM photo) of a porous surface deposited by screen printing on a support.
- the subject of the present invention is therefore a process for preparing a perovskite phase sol with controlled stoichiometry having at least four cations and being stable over time. After dipping (dip coating in English), during the crystallization of this sol temperature, an ultra-divided or nano structured architecture layer composed of perovskite phase particles with a diameter of 10-100 nm is deposited on the surface of the membrane. .
- An essential feature of this invention is the very large increase in grain boundaries at the membrane surface as well as the dramatic increase in the exchange surface area and oxygen flux through the membrane.
- the subject of the invention is therefore a process for preparing a sol-gel of at least three metal salts Mi, M 2 and M 3 which are suitable for the preparation of a material of the type perovskite corresponding to the general formula (I):
- x, y, u and ⁇ are such that the electrical neutrality of the crystal lattice is conserved, 0 ⁇ x ⁇ 0.9,
- A represents an atom chosen from scandium, yttrium or in the families of lanthanides, actinides or alkaline earth metals;

Evaporation of the solvents (ethanol and water) allows the gel solids to crosslink around surfactant micelles by forming bonds between the hydroxyl groups of one salt and the metal of another salt.
- the control of hydrolysis / condensation reactions related to electrostatic interactions between inorganic precursors and surfactant molecules allows cooperative assembly of the organic and inorganic phases, which generates micellar aggregates of controlled size surfactants within an inorganic matrix. .
- the phenomenon of self-assembly is induced by progressive evaporation of the solvent from a reagent solution, when the micellar concentration becomes critical.
- the starting point of the self-setting process is the hydroalcoholic solution of inorganic precursors (La, Sr, Fe and Ga) and nonionic surfactant.

- CMC is defined as the limiting concentration beyond which the phenomenon of self-arrangement of surfactant molecules in the solution occurs. Beyond this concentration, the chains of the surfactant tend to be grouped by hydrophilic / hydrophobic affinity. Thus, the hydrophobic bodies are grouped together and form spherical micelles. The ends of the polymer chains are pushed outwardly of the micelles, and associate during the evaporation of the volatile solvent (ethanol) with the ionic species in solution which also have hydrophilic affinities.

- the gels obtained after evaporation of the solvents are calcined in air.
- the removal of the surfactant during the heat treatment makes it possible to generate a cohesive matrix having a homogeneous and structured porosity.
- FIG. 4 illustrates the principle of self-assembly after soaking a substrate in a soil, said self-assembly being induced by evaporation, leading to the formation of a sol-gel which, after calcination, leads to an ultra-divided support of perovskite phase with controlled microstructure.

Furthermore, this deposit is stable under partial pressure gradient oxygen, a necessary condition for the use of a CMR for steam reforming methane but also to produce oxygen by separation of the air through said ceramic membrane.
- the second advantage comes from the thickness of the deposit and the deposition process. Indeed, the deposit is of a thickness 100 times smaller than by screen printing (material gain) and because of soaking, all dense diaphragm support geometries can be used (tubes, flat plates).
- the atomization technique makes it possible to transform a sol into a solid dry form (powder) by the use of a hot intermediate.
- the principle is based on the spraying into fine droplets of the soil (3), in a vertical cylindrical chamber (4) in contact with a hot air stream (2) in order to evaporate the solvent in a controlled manner.
- the resulting powder is entrained by the heat flow (5) to a cyclone (6) which will separate the air (7) from the powder (8).

- the spherical granules are hollow and the wall of the granules itself has a high porosity.
- the use of this powder to make porous layers would provide a dual-scale porosity and have a matrix with a high density of grain boundaries.
