稀土在我国化肥催化剂中的应用

Appilication of rare-earth in China's chemical fertilizer catalysts

添加稀土氧化物的转化催化剂和甲烷化催化剂是我国化肥催化剂的特色。文中概述了稀土在烃类水蒸气转化催化剂、甲烷化催化剂、中变催化剂、宽变催化剂、氨合成催化剂、二氧化硫氧化催化剂、氨氧化制硝酸催化剂及甲醇催化剂等方面的应用。

Catalysts for hydrocarbon steam-reforming and methanation added by rare-earth oxide makethe feature of chemical fertilizer in China.This paper describes the application of rare-earth in catalysts forhydrocarbon steam-reforming,methanation,mid-temperature water gas shift,wide-temperature water gasshift,ammonia synthesis,sulfur dioxide oxidation,preparation of nitric acid by ammonia oxidation andmethanol synthesis.
