建立了废气中含有甲苯、一氧化碳、丙烯混合物催化燃烧反应器的数学模型 .多组分混合物催化燃烧反应动力学模型采用吸附解离态的氧与吸附态的反应物反应的机理推导得到了反应速率方程 .模拟计算了废气处理量、废气中各组分的浓度、床层入口温度对转化率的影响 .

A one-dimensional mathematical model was presented for the catalytic combustion reactor. The conversions of toluene, carbon monoxide and propylene and the profile of temperature with the height of the catalytic bed were obtained. The effects of waste gas flow rate,inlet concentration and inlet temperature on conversion were simulated. The conversions of toluene, carbon monoxide and propylene decreased with increasing waste gas flow rate. In the mixture, the effect of the inlet concentration of toluene on the conversions of carbon monoxide and propylene is slight, but the inlet concentrations of carbon monoxide and propylene did affect the conversion of toluene. Reciprocal inhibition effects existed in the catalytic combustion of toluene, carbon monoxide and propylene.
