Sébastien Decker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Catalytic support with an oxide base from a metal belonging to the SVI group of the periodic table, its preparation and its uses
    Patent number: 6679986
    Abstract: A catalytic support includes a substantial quantity of at least one SVI group Periodic Table metal oxide in which is incorporated silica. The mass ratio between the quantity of SVI group metal oxide and the quantity of silica it contains ranges between 5 and 70, the SVI group metal oxide is in crystalline form, and the specific surface of the support is greater than or equal to 160 m2/g.

  • Acid catalyst with a sulfated zirconia base and its uses
    Patent number: 6448198
    Abstract: The invention relates to an acid catalyst containing a substantial quantity of supported or mass sulfated zirconia and at least one hydrogenating transition metal. This catalyst is characterized by the fact that the sulfated zirconia is in crystallized form and that it shows a specific surface area greater than or equal to 135 m2/g, a pore volume greater than or equal to 0.16 cm3/g and an average pore diameter greater than or equal to 20 Angstroms (20×10−10 m). The invention also relates to methods of making this catalyst and to the uses of this catalyst in hydrocarbon transformation chemical reactions requiring the use of an acid type catalyst, such as for example, isomerization, alkylation, oligomerization reactions or even light hydrocarbon dehydration reactions, and also heavier hydrocarbon hydrocracking and hydroisomerization reactions. In a preferred embodiment of the method of the present invention, a hydrated zirconia gel is washed with a soluble polar organic solvent (other than water).

  • Preparation process for ferrierrite zeolite and its uses as an isomerization catalyst of linear olefin in isoolefin or as a hydrocracking and hydroisomerization paraffin catalyst
    Patent number: 6136289
    Abstract: A process of preparing a ferrierite-type zeolite, with high crystallinity rate and having a anhydrous stage composition expressed by the formula M.sub.x (AlO.sub.2).sub.x (SiO.sub.2).sub.y, M being a cation of an alkaline metal such as Na or K, or a mix of both. The process contains a gel-producing step, by addition of boric acid to an aqueous aluminum-sulfate solution mixed with a aqueous solution containing oxides of Na and/or K and of Si, without the use of a structural agent. The invention also pertains to any zeolite obtained by this process, and its uses.
