The characteristics of catalytic combustion below 1000℃ with gas oil and kerosene were measured using practical catalysts, Pd-Al_2O_3 or Pt-Al_2O_3. A one-dimensional steady-state combustion model was developed to predict the temperature distribution in the catalyst. The following results were obtained. Pre-heating of the mixture up to about 300℃ was required to start the catalytic combustion. The fuel oxidation was controlled by the fuel diffusion from the mixture to the catalyst surface below about 700℃; the combustion efficiency was determined to be a function of the non dimensional number, Re・Sc・d/l. The gas-phase reactions were activated and combustion efficiency was increased at the burnt gas temperature higher than 700℃. The developed model was capable of predicting the combustion efficiency, the temperatures of the burnt gas and the catalyst.
