la-comonx/cnts催化剂上氨分解反应的本征动力学
, PP. 758-762
Keywords: 负载型金属氮化物,催化剂,氨分解,制氢,反应动力学
Abstract:
？以la-comonx/cnts为催化剂，对氨分解制氢反应的本征动力学进行了研究。考察了n2浓度、h2浓度、nh3浓度以及反应温度对反应速率的影响。采用幂指数方程描述反应动力学，确定了本征动力学参数，推导出了本征动力学方程，得到反应的活化能为93.948kj/mol。同时对其反应机理进行了探讨，认为la-comonx/cnts催化剂上氨分解反应遵循temkin-pyzhev机理，即表面氮原子的结合脱附为反应的速率控制步骤。
