摘要
介绍了对１２种候选氨催化分解催化剂筛选实验的结果，其中Ｎｉ－３催化剂具有最高的反应活性、一定的耐硫性能和长的使用寿命，是所选最优的催化剂。动力学研究表明，在５８０－６３０℃的温度区间内，反应为化学反应控制；在６３０－７００℃的温度区间内，反应以扩散影响为主；在７００℃以上的温度区间内。
In this article,12 candidate catalysts for ammonia catalytic decomposition have been screened.Of them, Ni-3 catalyst was the most excellent catalyst because of its highest activity, anti-sulfur property and long life. Further kinetic researches exhibited that the reaction rate is controlled by chemical reaction within the reaction temperature 580630 , seriously effected by diffusion within 630700 ,and above 700 , influenced by reaction equilibrium to great degree.
