【Abstract】 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.更多还原
