    摘要： A process for preparing a supported metal catalyst composition which comprises impregnating microspheroidal support particles with a solution of at least one catalytically active metal, or precursor, drying the impregnated support particles and then treating the mobile metal, or precursor in a mobile state with a liquid comprising at least one reducing agent to deposit and immobilize the metal, or its precursor, in the support particles such that the metal, or its precursor, is distributed in the support particle in a layer below the surface of the support particle, the layer being between an inner and an outer region having a lower concentration of metal or precursor. Also, a composition comprising microspheroidal support particles having at least one catalytically active metal or precursor thereof distributed in a layer below the surface of the particles, the layer being between an inner and an outer region of the support particle each having a lower concentration of metal or precursor.

    摘要： Process for preparing a supported metal catalyst composition comprising impregnating support particles having a mean diameter of greater than 300 microns with a solution of least one catalytically active metal, or precursor thereof, such that the metal, or its precursor, is in a mobile state in the support particles; and drying the impregnated support particles. The mobile metal, or its precursor, in the support particles is then treated with a liquid comprising at least one reducing agent to deposit and immobilize the metal, or its precursor, in the support particles such that the metal, or its precursor, is distributed in the support particle in a layer below the surface of the support particle, the layer being between an inner and an outer region, each of the inner and outer regions having a lower concentration of the metal or precursor than the layer.
