摘要
采用分子筛掺杂和金属离子掺杂的方法 ,制备了反应性能较好的三聚氰胺合成催化剂。反应性能分别提高了19 %和 15 % ,通过XRD ,NH3
The novel catalysts having a significantly higher activity for synthesis of melamine from urea,have been developed by mixed with zeolite or zeolite and metal cation.The activities of the reaction over Si Al Z,Si Al Z M were increased 15%,20% respectively.The result of NH_3 TPR indicated that the acidic centers over the catalysts for synthesis of melamine from urea is the active centers of the reaction.
