摘要
本文综述了第二代氨合成催化体系——钌系氨合成催化剂的研制、开发及工业应用情况。介绍了钌系氨合成催化剂的载体、促进剂、钌活性前身物对氨合成催化活性的影响。比较了钌系氨合成催化剂与铁系氨合成催化剂的反应机理与性能特点。
Ruthenium catalysts are considered as the second-generation catalysts for ammonia synthesis following iron catalysts. The article summarizes advances in research and industrial application of ruthenium-based ammonia synthesis catalysts. Ruthenium catalysts are known to be quite sensitive to the nature of supports, promoters and precursors in ammonia synthesis. The different characteristics and kinetics between ruthenium catalyst and iron catalyst are described. Kellogg advanced ammonia process (KAAP) supplies the strong support for industrial application of ruthenium catalysts.
