| 摘要 |
A method is described for preparing a catalyst suitable for use in a steam reforming process, comprising the steps of: (i) spraying a slurry containing a particulate catalyst compound, comprising one or more catalytic metals selected from the group consisting of Ni, Cu, Pt, Pd, Rh, Ru and Au, on to the surface of a shaped support in a pan coater to form a coated shaped support material having the catalytic metal in a surface layer, (ii) drying and optionally calcining the coated shaped support material to form a catalyst precursor, and (iii) optionally reducing the metal or metals in the catalyst precursor to a lower oxidation state to form the catalyst. Use of the egg-shell catalyst for performing a steam reforming reaction. |
