The present invention comprises the steps of preparing a precursor compound of one or more other elements of Pt, Sn, and La or Cs, and one or more multiple solutions containing a precursor compound of ZrO 2 ; Converting the solution into an aerosol; Introducing the aerosol directly or indirectly into a heated pyrolysis zone; Performing pyrolysis; And separating the formed particles from the pyrolysis gas, and to a catalyst particle comprising at least one additional element selected from platinum and tin, and lanthanum and cesium on zirconium dioxide as a support. Suitable precursor compounds include zirconium (IV) acetylacetonate, lanthanum (II) acetylacetonate and cesium acetate, hexamethyldisiloxane, tin 2-ethylhexanoate, platinum acetylacetonate, zirconium (IV) in n-propanol Propylate and lanthanum (II) acetylacetonate. The invention also relates to catalyst particles produced using the process according to the invention and to the use of such particles as dehydrogenation catalysts. |
