| Abstract: | Methane reforming by carbon dioxide and oxygen was investigated over 5 wt.%Ni/CaO-SiO2 catalyst in a fluidized-bed reactor. The catalyst exhibited high activity and good stability at stoichiometric methane, carbon oxide and oxygen feed. Effects of calcium loading, space velocities, reaction temperatures and the feed gas compositions for this combined reaction were investigated. These results indicated that Ni/CaO-SiO2 is more effective and stable. The catalyst performance, stability, structure, dispersion of nickel and carbon deposition of the modified and unmodified catalysts were investigated by a series of characterization techniques. Results showed that catalysts modified with CaO improved their stability better than the pure nickel-based catalysts. This revised version was published online in June 2006 with corrections to the Cover Date. |
