CeO2对CO选择性氧化催化剂氧传递速率的影响及模型模拟

摘要

采用共沉淀法和浸渍法制备了5％CuO／AlO3催化剂，用脉冲H2滴定法研究助剂CeO2对CO选择性氧化催化剂反应过程中氧的传递速率的影响，并建立数学模型进行了模拟计算，得出助剂CeO2对CuO／Al2O3催化剂氧传递速率的影响规律。%The 5% CuO/Al2O3 catalyst was made by chemical coprecipitation-gel and dip-molding method. The titration of pulse-H2 was adopted to research the effects of adding different content CeO2 on oxygen evolution rate in CuO catalyst, and also mathematical model was set up to simulate the result of the oxygen evolution rate, and the effects of adding different content CeO2 on oxygen evolution rate were found out.
