The emission problem of a catalytic combustor using methanol mixture arises during the start-up condition. A modified quasi-steady-state model is used to analyze the transient behavior of the catalytic combustor. Parameters considered in this study were air-fuel ratio, preheat temperature of the catalyst, space velocity, heat input, catalyst length, combustion efficiency and heat loss coefficient. From the numerical computation, the range of operating parameters of the catalytic combustor during transient condition can be predicted with sufficient accuracy. The transient combustion efficiency was found to be greatly affected by the space velocity, preheat of the catalyst and air-fuel ratio. At a condition of the air-fuel ratio and heat input, the required catalyst length to achieve a certain combustion efficiency can also be predicted.
