Definitions
- the invention relates to a process for the preparation of aluminates containing at least one element A from the group consisting of Sr, Ba and La and at least one element B from the group consisting of Mn, Fe, Co, Ni, Rh, Cu and Zn, the hexaaluminates itself as well as their use.
- composition BaMno.sMgo.sAlnO-ig-a, BaMgAlnO-ig-a, BaMnAlnO-ig-a and SrMnAlnOi9-6- In one example, a solution of aluminum nitrate, lanthanum nitrate, manganese nitrate and magnesium nitrate in water with Ammonia added, the precipitate separated, washed and calcined at 600 ° C to 1200 ° C in air. A composition of the formula Lao, 78Mgo, 9Mno, 9AlnOi9-a is obtained.
- the disadvantage here are also the long Calcinier regulations. These are in the examples 16 h at a temperature of 1200 ° C after Vorkalzination of 4 h at a temperature of 600 ° C.
- the hexaaluminates obtained have specific surface areas of less than 20 m 2 / g.
- M1 is selected from La, Ce, Nd, Sm, Eu, Gd, Er, Yb and Y,
- M2 is selected from Mg, Ca, Sr and Ba, and
- M3 is selected from Mn, Fe, Co, Ni, Cu, Ag, Au, Rh, Ru, Pd, Ir and Pt,
- hexaaluminate catalyst As an application of the hexaaluminate catalyst is called the catalytic combustion of hydrocarbons to reduce NOx emissions.
- This process involves two high temperature calcination steps.
- the preparation of the modified alumoxane takes place at temperatures around 800 ° C and a holding time of 1 h.
- the hexaaluminate is produced at temperatures around 1300 ° C and a holding time of 3 h.
- the hexaaluminates obtained in the examples have specific surface areas between 5 and 10 m 2 / g.
- EP 2 1 19 671 A1 discloses a process for the preparation of hexaaluminates comprising the steps of a) providing a porous template material,
- lanthanum hexaaluminates of the formulas LaAlnOis, LaMnAlnO-ig and LaMgAlnOi9 are obtained by impregnating a carbon xerogel with an aqueous solution of lanthanum nitrate, aluminum nitrate, magnesium nitrate and manganese nitrate, drying and calcining at 1300 ° C in an inert gas atmosphere and removing the template material by calcination at 1000 ° C made in air. Also disclosed is the use of hexaaluminates in the catalytic combustion of lean fuel mixtures to minimize NO x and CO emissions.
- A is at least one element of Ca, Sr, Ba and La,
- B is K and / or Rb

- RWGS reaction reverse water gas shift reaction
- WO 2013/1 18078 and US20131 161 16 disclose the use of various mixed metal oxides as catalysts for the reforming of hydrocarbons, preferably methane, and CO2.
- hydrocarbons preferably methane, and CO2.
- non-phase pure hexaluminates are described with specific surface areas of less than 20 m 2 / g, which are obtained by several hours Caicintechnik at 1100 ° C.
- the object of the invention is to provide a simple and inexpensive process for the preparation of aluminates, preferably hexaaluminates with high specific surface area.
- the aluminates are said to be thermally and chemically stable with respect to their sintering properties and their coking behavior in a gas atmosphere containing hydrocarbons such as methane and at higher temperatures (500-1000 ° C).
- the object of the invention is in particular to provide a simple process for the preparation of aluminates, preferably hexaaluminates, which are suitable as reforming catalysts for the production of synthesis gas from methane and carbon dioxide and as catalysts for the RWGS reaction.
- the object is achieved by a process for the preparation of aluminates of the general formula (I)
- y is a value determined by the oxidation states of the other elements, comprising the steps of (i) providing one or more solutions or suspensions containing precursor compounds of elements A and B and a precursor compound of aluminum in a solvent,
- Aluminates according to the invention may be complex aluminates of the hexaaluminate type (hexaaluminates) or of a structure type related to the gamma A c.
- the aluminate, preferably hexaaluminate, of the general formula (I) forming precursor compounds of elements A and B and the aluminum are fed to the pyrolysis zone as an aerosol. It is expedient to supply to the pyrolysis zone an aerosol which is obtained by nebulization of only one solution which contains all precursor compounds. In this way, it is ensured in each case that the composition of the particles produced is homogeneous and constant.

- the solution or solutions may contain both polar and non-polar solvents or solvent mixtures.
- the solution or solutions preferably contain the precursor compounds of elements A, B and of aluminum in the stoichiometric ratio corresponding to formula (I).

- the pyrolysis reactor can be indirectly heated from the outside, for example by means of an electric furnace. Because of the temperature gradient from outside to inside required for indirect heating, the furnace must be much hotter than the temperature required for pyrolysis. Indirect heating requires a temperature-stable furnace material and a complex reactor design, the required total amount of gas is, on the other hand, lower than in the case of a flame reactor.
- the pyrolysis zone is heated by a flame (flame spray pyrolysis).

- a flame spray pyrolysis device generally comprises a reservoir for the liquid to be atomized, feed lines for carrier gas, fuel gas and oxygen-containing gas, a central aerosol nozzle and an annular burner arranged around it, a device for gas-solid separation comprising a filter element and a removal device for the solid and an outlet for the exhaust gas.
- the cooling of the particles is carried out by means of a quenching gas, e.g. Nitrogen, air or water vapor.
- the pyrolysis zone comprises a so-called pre-dryer, which pre-dries the aerosol by evaporation of the solvent before it enters the pyrolysis reactor, for example in a flow tube with a heating unit arranged around it. If pre-drying is dispensed with, there is a risk that a product with a broader grain spectrum and, in particular, too much fines will be obtained.
- the temperature The temperature of the pre-dryer depends on the nature of the dissolved precursors and their concentration.
- the temperature in the pre-dryer is above the boiling point of the solvent to 250 ° C; in the case of water as solvent, the temperature in the pre-dryer is preferably between 120 and 250 ° C., in particular between 150 and 200 ° C.

- the combustion chamber may also be a simple combustion chamber.
- a pyrolysis gas containing nano-particles of varying specific surface area is obtained.
- the size distribution of the particles obtained can essentially be obtained directly from the droplet spectrum of the aerosol supplied to the pyrolysis zone, the concentration and the volume flow of the solution or solutions used.
