Ni-Fe-Ce Mixed Nano-composite Oxide Catalyst Prepared by Solution-spray Plasma Technique for High Temperature Water-gas-shift Reaction

摘要

Catalytic activity and selectivity of NrFe-Ce oxide nano-composites prepared by the solution-spray plasma technique for the high temperature water-gas-shift reaction were investigated. The composite catalyst exhibited higher activity than a commercial Fe-Cr catalyst at 673 K. Compared with an NrFe-Al oxide nano-composite prepared by the same method, the CO methanation reaction was suppressed remarkably, without serious loss of activity for the water-gas-shift reaction.
