摘要
以铁钼系催化剂作为甲苯气相氧化的催化剂，在排除内外扩散的条件下，在温度４３０～４６０℃范围内，采用连续固定床积分反应器对甲苯气相氧化动力学进行了研究，建立了４个表征反应机理动力学模型，用非线性回归方法进行关联，根据偏差最小的准则，获得最佳动力学模型及相关参数。
The kinetics of the vapour-phase oxidation of toluene on Fe-Mo catalyst was studied in acontinuously operated fixed-bed integral reactor under the condition of eliminating the influence of externaland internal diffusion. Four rival kinetic models was postulated and fitted with the experimental data bynonlinear regression. According to the principle of minimun relative error,the best kinetic rate expressionwas obtained and its parameters were evaluated.
