Patent ID: 7087191

Claim:
A process for preparing a shell metal catalyst or a precursor of a shell metal catalyst, which comprises the steps of: (1) applying a slurry comprising a diluent, cobalt or a precursor compound thereof, and optionally a first refractory oxide of an element selected from the group consisting of those having an atomic number of at least 20 and at most 92 or a precursor of the first refractory oxide thereof, onto the surface of particles of a core carrier, forming a wet coating, wherein the slurry comprises at least 5 wt. % of the cobalt or the precursor compound thereof, calculated based on the weight of the metal relative to the weight of a calcination residue which is formed from the slurry by drying and calcining, and (2) removing at least a part of the diluent from the wet coating to form a dried coating on the core carrier.
