摘要
应用程序升温还原(TPR),x-射线行射(XRD)和热分析技术,对共沉淀铁锰催化剂的还原性能及不同还原阶段催化剂的体相组成进行了探讨,结果表明:锰对铁的还原性能有促进作用,铁锰在还原过程中发生了相互作用,形成尖晶石结构。
The reduction perfomance of co-precipitated iron-manganse catalysts andthe bulk composition of catalysts at various reduction stages have been studied bytemperature programmed reduction(TPR), X-ray diffraction (XRD) and thermal analysis.It is shown that manganese promotes the reduction of iron. The interation between iron and mangenese takes place at the process of reduction to form spinel structure.
