Disclosed is a new method for preparing supported metal catalysts with eggshell active metal profile. The organometallic compounds with metal as Pd, Ni, Co, Mo, Cu, Pt, Fe, Ag, Ir, Pb, Ti, Sn, V, and Zn, etc., are dissolved in a pure organic solvent, such as benzene, toluene, xylene, methanol, ethanol, and tetrahydrofuran (THF), etc., and/or an organic solvent mixture thereof. The catalyst precursors (i.e., the reactive metal of the prepared organic or inorganic metal concentrated solution) are carried to the surface of MgO, Al2O3, SiO2, TiO2, ZrO2, zeolite, active carbon, and polymer support by wet impregnation and/or spray method. The metal concentration profile and metal loading can be precisely controlled by choosing suitable solvent and/or operation conditions.

ouvelle méthode de préparation de catalyseurs métalliques sur support à profil de métal actif en coquille. On dissout les composés organométalliques, qui contiennent divers métaux (ex. : Pd, Ni, Co, Mo, Cu, Pt, Fe, Ag, Ir, Pb, Ti, Sn, V et Zn), dans un solvant organique pur, tel que le benzène, le toluène, le xylène, le méthanol, l'éthanol, le tétrahydrofurane (THF) etc., ou dans un mélange de ces solvants organiques. On pose les précurseurs catalytiques (autrement dit les métaux réactifs de la solution concentrée de métal organique ou inorganique préparée) sur des supports de MgO, de Al2O3, de SiO2, de TiO2, de ZrO2, de zéolite, de charbon activé et de polymères par imprégnation à l'eau ou par une méthode de pulvérisation. La concentration métallique et la charge métallique peuvent être contrôlées avec précision en choisissant le solvant et/ou les conditions d'utilisation appropriés.
