Study on the reason of catalyst deactivation during the production of hydrogen by partial oxidation and steam reforming of gasoline

对汽油氧化重整制氢反应催化剂失活因素进行了理论分析与实验研究 ,研究结果表明 :在进行反应中 ,催化剂表面积碳是造成催化剂失活的原因 ,为避免催化剂表面积碳 ,反应的最小水碳比应大于理论计算的最小水碳比。

The main factor for the catalyst to lose its activity during the production of hydrogen by partial oxidation and steam reforming of gasoline is analyzed and studied. The result shows that the reason for the catalyst to lose its activity is that the carbon deposits on the catalyst surface during the reaction. The minimum ratio of molH 2O/molC during the experiment should be higher than the theory calculation ratio of molH 2O/molC in order to prevent the catalyst losing its activity. The theory minimum ratio of molH 2O/molC at different reaction temperature is determined.
