【摘要】 建立了结焦催化剂在固定床反应器中再生过程的一维拟均相非稳态数学模型，采用有限差分法求出了其数值解。据此模型得出的产物浓度－ 时间分布曲线与试验结果吻合良好更多还原

【Abstract】 A pseudo homogeneous one dimension model of the regeneration process of coked catalysts in fixed bed reactors is presented. By means of the finite difference method, a numerical solution of this model is obtained. The concentration profiles obtained from the model are in good agreement with experimental results.更多还原
