Influence of the Ni/Co ratio in bimetallic NiCo catalysts on methane conversion into synthesis gas

摘要

Mesoporous NiCo-Gd0.1Ti0.1Zr0.1Ce0.7O2 catalysts with a variable Ni/Co ratio were synthesized by co-precipitation with sonication. The catalysts exhibited high activity and selectivity for synthesis gas production by CH4-O-2 and CH4-CO2 reforming at 850-950 degrees C. The catalyst with 80Ni/20Co demonstrated the best results in the partial oxidation and dry reforming of methane.
