The aim of this study is to simulate the combustion behavior in the combustor with plate catalysts. The burning of low-calorific gas composed of hydrogen and carbon dioxide was simulated, and the temperature of the plate catalyst and hybrogen burnout were predicted. From this study, the following conclusions were obtained. (1) If the excess air ratio, λ, is less than 2.4, the catalyst temperature distribution has a knick point, at which gradient of the temperature changes abruptly. (2) When λ is less than 2.4, the catalyst temperature and the burnout become large with the increase of λ, while when λ is larger than 2.4, the temperature decreases with the increase of λ and the burnout becomes constant. (3) When λ is constant, the burnout decreases with the increase of the velocity.
