The methods of perparing catalysts for producing hydrogen with gasoline by partially oxidizaing and reforming have been studied.The reactivity of gasoline producing hydrogen,selectitity of producing hydrogen and stability of M N/Al 2O 3 catalyst have been studied whether the catalyst has been reduced or not.It showed that the catalyst reactivity and selectivity for gasoline to producing hydrogen by partially oxidizing and reforming differed with the preparation methods.The paper reached a conclusion that the reduced catalyst was better than the non reduced catalyst for the catalyst reactitity and selectivity.However,it did not have remarkable effect on catalyst stability.
