Methanation of syngas under atmospheric pressure was investigated over Ni-based catalysts modified by Fe and TiO2.
The optimal Ni/Fe ratio for Ni-Fe/Al2O3 catalyst (15 wt% Fe) was estimated to be 1 for the methanation of syngas.
Ni-Fe/TiO2-Al2O3 catalyst exhibits outstanding performance for methanation and long-life stability.
