Beschreibung
Zusammenfassung:The invention provides a catalyst for ammonia production and a preparation method and application thereof, the catalyst for ammonia production is SnxTi (1-x) O2, x represents the molar ratio of Sn/(Sn + Ti); the catalyst has the advantages of high-temperature stability, wide temperature window, high conversion efficiency of isocyanic acid (HNCO), high ammonia production rate, high ammonia selectivity and the like, can maintain high ammonia production efficiency in a wide temperature window range, and reduces the operation and production cost at the same time. 本发明提供一种制氨的催化剂及其制备方法、应用，所述制氨的催化剂为SnxTi(1-x)O2，其中，x表示Sn/(Sn+Ti)摩尔比；具有高温稳定性、温窗较宽、异氰酸(HNCO)的转化效率高、产氨率高和氨选择性高等优点，在较宽的温度窗口范围内能维持较高的产氨效率，同时降低了运行生产成本。
