同位素交换技术研究CO_2-CO和铁氧化物体系的反应及方法分析

Using Isotope Exchange Technique to Study the Reaction Between CO_2-CO and Iron Oxides System and Methods Analysis

用同位素交换技术研究了CO2-CO与铁氧化物体系的反应。考察了反应速率常数随反应气体流量的变化,介绍了处理同位素交换法所获得数据的两种方法:方法1从反应界面CO2分解反应的角度计算反应速率常数;方法2从反应界面CO生成反应的角度计算反应速率常数。根据对试验所测数据的计算,比较和分析了两种计算方法的不同,并对方法1进行了修正,得到了和方法2完全一致的计算结果。

Isotope exchange technique was used to study the reaction between CO2-CO and iron oxides system,the effect of the gas flow rate on the reaction rate constant was investigated,two methods that analysis the dates obtained by isotope exchange technique were introduced： The first way is to calculate reaction rate constant based on the CO2 dissociation reaction on the interface,and the second way is to calculate reaction rate constant based on the CO formation reaction on the interface.On the basis of the comparison of the calculated results,the different of two calculation ways was analyzed,and the first way was modified with the consistent results obtained by the second way.
