Abstract

Ni-loaded Mg(Al)O catalysts with a Mg/Ni/Al molar ratio of 2.5/0.5/1.0 were prepared by coprecipitation and were tested in partial oxidation, steam reforming (SR), dry reforming and autothermal reforming (ATSR) of CH₄. Trace Pt-doped Ni/Mg(Al)O exhibited sustainable activity even under oxidative conditions, i.e., steam-oxygen-purged SR and steam-purged ATSR. These catalysts showed "intelligent" catalytic behaviors, i.e., self-activation and self-regenerative activity, as well as high turn-over frequency values in daily start-up. It is most likely that the crystal structure of Mg(Al,Ni) periclase played an important role in the self-regenerative activity by reversible reduction-oxidation between Ni⁰ and Ni²⁺ inside of the periclase assisted by steam and Pt (or Ni-Pt alloy) on the Pt/Ni/Mg(Al)O catalyst. This is an abstract of a paper presented at the 20th Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals (Dharan, Saudi Arabia 12/5-6/2010).
