Low temperature catalytic oxidation of solid carbon was conducted in a fluidized bed reactor with/without a non-equilibrium discharge. Solid carbons like as soot, PM, and char cause many operational problems and have lower reactivity. We tried to oxidize such carbon particles to carbon oxide and/or carbon dioxide by lattice oxygen in/on the oxide catalysts at lower temperature. To maintain high contact frequency between the catalyst and carbon particles, we applied a fluidized-bed reaction apparatus for this reaction. As a result, we found that carbon particles are oxidized at 673K by the lattice oxygen in/on the catalyst. Among various oxide catalysts, Fe/CeO_2 and some other catalysts showed higher activity for the oxidation of carbon particles.
