Definitions
- This invention relates to a process for the preparation of a new family of mesoporous inorganic particles; the process makes it possible to precisely control the particle size distribution and the morphology of the prepared particles which can advantageously be used as catalyst supports, as catalysts and / or for the separation of compounds in the gas phase having different boiling points as well as for the packing of chromatography columns.
- Prior art
- Mesoporous particles are very useful in the industrial field, both as catalysts, catalyst supports but also as adsorbents insofar as their high porosity expressed in terms of surface area to volume ratio allows the molecules with which they are brought into contact to easily access the core of the particles and react on a large surface thus enhancing the catalytic and / or adsorbent properties of these materials.
- MOBIL describes a method for preparing a composition of matter consisting of an inorganic, non-lamellar and crystalline phase having, after calcination, an arrangement of pores of uniform size equal to at least 1, 3 nm, with at least minus an X-ray diffraction peak corresponding to a reticular distance greater than 1.8 nm and having a benzene adsorption capacity greater than 15% by weight at 25 ° C. and 50 torr from a HiSil type silica mixed with a solution of tetramethylammonium silicate.
- syntheses of silicic mesoporous solids are carried out using tetraethylortho silicate (TEOS), a tetraalkylammonium or sodium silicate, precipitated silica.
- TEOS tetraethylortho silicate
- a tetraalkylammonium or sodium silicate precipitated silica.
- TEOS has the disadvantage, besides being an expensive reagent, of generating ethanol during hydrolysis. But, used in a non-basic medium, it is the only source of silica which makes it possible to prepare particles of mesoporous solids of a few ⁇ m.
- Another disadvantage of syntheses of mesoporous solids in neutral or acid medium relates to the yield of surfactant expressed as the ratio between the surfactant introduced at the start of synthesis and the surfactant retained in the solid formed which is clearly less than 100%.
- the granulation produces particles in the form of beads, therefore rather spherical, with a distribution of. large size, which, for certain applications, can constitute a handicap.
- the only way with this technique to obtain particles with a narrow particle size distribution is to make particle size selections subsequent to the actual granulation step to the detriment of yield and / or productivity.
- granulation is a technique rather suitable for particle sizes greater than one millimeter; - compaction is mainly used for the formulation of pharmaceutical products and concerns particles of even larger sizes: a few mm at least;

- W represents one or more divalent elements, such as manganese, cobalt, iron and / or magnesium,
- X represents one or more trivalent elements, such as aluminum, boron, iron and / or gallium
- Y represents one or more tetravalent elements, such as silicon and / or germanium, and preferably silicon

- the crystallization temperature is generally between room temperature and 200 ° C and the duration of the crystallization reaction can generally range from a few minutes to a few days.
- the duration of the reaction step is controlled and optimized by SEM and laser granulometry, a reaction time that is too long risking increasing the level of fines.

- an oxide source should be used, the particle size distribution of which is narrow. 4.
- the pH allows the thickness of the walls to be varied: an interpretation commonly accepted by many authors is that in basic medium, silica is organized around the micelles of the surfactant by interaction between the cationic head of the surfactant and the ionized silanol groups which are found on the surface of the silica.
- the mesoporous volume corresponding to pores ranging from 4 to 15 nm is greater than or equal to 0.7 cm 3 / g, and preferably greater than or equal to 1 cm 3 / g,
