摘要：

Nickel and iron supported on Al2O3, ZrO2, TiO2 and SiO2 containing Ni and Fe in the ratio of 3:1 showed a higher CH4 yield compared to the supported Ni catalysts. The Nb2O5 supported catalyst was an exception. The relative enhancement in yield for the most active catalyst of each series was support dependent, and the maximum enhancement was achieved when Al2O3 was the support. It appeared that the enhancements in yield was due to formation of a suitable Ni-Fe alloy and the maximum enhancement for the Al2O3 supported catalysts was due to the ability of the support to adsorb CO2.
