摘要: A series of different-sized Ni catalysts (4.5–45.0 nm) were prepared and used for methane autothermal reforming with CO2 and O2 in a fluidized-bed reactor. It was found that the activity and stability of Ni catalysts depend strongly on the particle size and the operating space velocity. Small sized Ni is more active and stable at space velocity< 54,000 h− 1. Characterizations disclosed that methane decomposition rate decreases with the enlarging Ni particle size, and some of the surface carbons (derived from methane decomposition) are …
