| Abstract: | 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. |
