ombustion characteristics of C3H8 in fluidized bed catalytic combustion, using platinum catalyst mixed with bed material, have been studied experimentally. The fluidized bed material was alumina, in which a supported platinum catalyst was mixed to a percentage weight ranging from 1 to 8. Particle diameter of the bed material was fixed to 0.3-0.355 mm and a static bed height was 20 mm. An increase of combustion temperature or catalyst mixing ratio in the fluidized bed material increases the combustion efficiency. However, the results revealed that catalyst mixing ratio exerts an influence mainly at low mixing ratio. Combustion efficiency almost reaches 100% under the conditions that catalyst mixing ratio was higher than 4% and combustion temperature-was 950K. No NOx formation was detected under these conditions.
