  • Publication number: 20160317998
    Abstract: A method for preparing a crystallized solid material of formula LiCl.2Al(OH)3,nH2O with n being comprised between 0.01 and 10, includes mixing in an aqueous medium, at least one source of alumina and at least one source of lithium in order to obtain a suspension, filtering the resulting suspension obtained for obtaining a slurry, followed by drying the obtained slurry at a temperature between 20 and 80° C. for a period between 1 h and 12 h, then shaping by extrusion the resulting dried slurry, directly after the drying to obtain extrudates, where the shaping was carried out without any binder, and then the drying of the obtained extrudates at a temperature comprised between 20 and 200° C. for a period between 1 hour and 20 hours, in order to obtain the crystallized solid material of formula LiCl.2Al(OH)3,nH2O as extrudates. A method for extracting lithium from saline solutions uses the thereby prepared material.

  • Publication number: 20140357471
    Abstract: The present invention concerns spheroidal alumina particles, catalysts comprising such particles as a support and a process for the production of spheroidal alumina particles, comprising the following steps: a) preparing a suspension comprising water, an acid and at least one boehmite powder for which the ratio of the crystallite dimensions in the [020] and [120] directions obtained using the Scherrer X-ray diffraction formula is in the range 0.7 to 1; b) adding a pore-forming agent, a surfactant and optionally water, or an emulsion comprising at least one pore-forming agent, a surfactant and water to the suspension of step a); c) mixing the suspension obtained in step b); d) shaping the spheroidal particles by the oil-drop method using the suspension obtained in step c); e) drying the particles obtained in step d); f) calcining the particles obtained in step e).

  • Patent number: 8871877
    Abstract: The present invention relates to materials and particularly “organometallic-organic-inorganic hybrid materials” that can be used as heterogeneous catalysts for selective catalytic reactions. More precisely this invention relates to organic-inorganic hybrid nanostructured materials comprising a regularly distributed stabilized carbene that binds strongly to a metal so as to form a stable organometallic-organic-inorganic hybrid material having high catalytic performances.

  • Publication number: 20110257006
    Abstract: The present invention relates to a process for producing a structured porous material comprising a structured inorganic framework made up of metal-oxide based walls in which nanoparticles of metal 0 are incorporated, which comprises the following steps: a) formation of a suspension of hydrophilic nanoparticles of metal 0 stabilized by non-exchangeable ligands that give the nanoparticles their hydrophilic character; b) growth of the inorganic framework from an inorganic precursor around the nanoparticles of metal 0 stabilized by the non-exchangeable hydrophilic ligands, in the presence of a pore-forming agent; and c) elimination of the pore-forming agent and at least partially of the non-exchangeable ligands that give the nanoparticles their hydrophilic character.
