Symposium High Temperature Electrochemistry IV
Presentation Title Molten salt-promoted NieFe/Al2O3 catalyst for methane decomposition

On-Site Speaker (Planned) Qian Xu
Abstract Scope Bimetallic NieFe/Al2O3 catalysts were prepared by the molten salt method, and the catalytic performance of the NieFe/Al2O3 catalysts with the KCleNiCl2 melt for methane decomposition was evaluated at 800 C. The catalysts and carbon products were characterized by XRD, SEM/EDS, XRF and Raman spectroscopy techniques. The results show that molten salt-promoted NieFe/Al2O3 catalysts exhibit high activity and long-term stability up to 1000 min time on stream without any deactivation. The carbon products over the molten salt-promoted NieFe/Al2O3 catalysts are in the form of small granular particles instead of filamentous carbon for the catalyst without molten salt. The promotional effect of the molten salt may attribute to the higher wettability of the FeeNi alloy by molten salt,which can prevent the catalysts from deactivation due to carbon encapsulation.
