【摘要】 :两阶段一级反应动力学模型和广义动力学模型被用来描述湿式氧化 ( WAO)及催化湿式氧化 ( CWAO)反应过程 ,并确定了动力学参数 .2个模型的计算值均与实验值相符 ,而广义动力学模型相对更准确些 .2个模型均表明反应分 2个步骤 :首先是H-酸被迅速氧化成小分子有机酸 ,后者再缓慢氧化 .这 2个步骤由模型参数加以表征 ,因而模型可被用来对 CWAO催化剂进行评价 .更多还原

【Abstract】 The Two step First order Reaction Kinetic Model and the Generalized Kinetic Model are employed to simulate the exprerimental processes of the Wet Air Oxidation(WAO)and the Catalytic Wet Air Oxidation(CWAO).The kinetic parameters are determined.The values calculated from the two models are well correspondent with the experimental data,and the Generalized Kinetic Model is relatively more accurate.Both models show the reaction has two steps:firstly the H acids are rapidly oxided as intermediate products and then these low molecular organic acids are slowly oxided.Two steps are evaluated by the models′ parameters.So the models can be used to evaluate the catalyst used in the CWAO of H acid solution.更多还原
