  • Publication number: 20100311571
    Abstract: Methods are disclosed herein for improving efficient catalyst utilization in processes including thermal catalysis using dry nanoparticle promoters, rather than salts of metal promoters in liquid form. Using selected process steps, the nanoparticles are more controllably dispersed on primary support particles, for effective use on secondary supports when it desired to bring reactants into contact with the secondary support. Applications that generally make use of these catalysts can be but are not limited to: emission abatement catalysts, generation of syngas, generation of liquid fuels from syngas, safety systems (hydrogen recombination catalysts in nuclear power plants) and many industrial processes.

  • Patent number: 7829493
    Abstract: The invention relates to a method of preparing metallic nanoparticles and to the materials thus obtained. More specifically, the invention relates to a method of preparing metallic nanoparticles consisting in: selecting a precursor from the salts, hydroxides and oxides of metallic elements that can be reduced at temperatures below the clay silicate network destruction temperature; and depositing said precursor on a support selected from pseudolaminar phyllosilicate clays. According to the invention the method comprises: (i) a deposition step in which the precursor is deposited on the support: (ii) when the precursor is selected from among salts and hydroxides, a thermal decomposition step in a controlled atmosphere, in which the precursor is subjected to a decomposition process and is transformed into an oxide of the metallic element: and (iii) a reduction step in which the oxide of the metallic element is subjected to a reduction process in a controlled atmosphere.

The resulting stabilized impregnating solution can be supplemented with additional Group VIII metal in water-soluble form to achieve increased levels of such metal in the final catalyst. Furthermore, uncalcined catalyst carriers impregnated with the stable solution and subsequently shaped, dried and calcined, have unexpectedly improved performance when used in the hydroprocessing of heavy hydrocarbon feedstocks.

  • Publication number: 20080223756
    Abstract: A method for producing an adsorbing agent, an absorbing agent obtained by the method, and its use as bleaching earth, in particular for refining oils and fats, is described. In the method according to the invention, a raw clay with a specific surface area of more than 200 m2/g, an ion exchange capacity of more than 40 meq/100 g and a pore volume of more than 0.5 ml/g is used. At least 40% of the pore volume are provided by pores which have a pore diameter of at least 14 nm, and at most 25% of the pore volume are provided by pores which have a diameter of less than 7.5 nm. Surface activation with an acid gives an adsorbing agent which has a bleaching activity which partly exceeds that of high performance bleaching earths obtained by intensive dealuminization and washing with strong acid.
