Catalytic behaviour of 0.5wt%Co/TiO2, prepared from TiO2containing only anatase phase, in CH4/CO2reforming at 2 MPa was strongly affected by reduction temperature. Co/TiO2reduced at relatively lower temperatures (<1123 K) lost all of its activity at the beginning of the reaction, whereas the catalyst reduced at higher temperatures (1123 K) showed relatively stable activity with only a slight amount of deposited coke. However, the latter catalyst lost all of activities at a higher space velocity after the reaction for 20 h, mainly due to oxidation of metallic Co. The addition of trace amounts of noble metals (Pt or Ru) improved the catalytic stability drastically by retarding the oxidation. It was confirmed that the strong resistant nature of Co/TiO2to coke deposition was retained after the addition of the noble metals.
