Abstract:
1. A 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 and then treating the mobile metal, or its precursor, in the support particles 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 said support particle, said layer being between an inner and an outer region, each of said inner and outer regions having a lower concentration of said metal or precursor than said layer.
