- •
Combination of CeO2 with Al2O3 promotes the reduction of Ni species.
- •
Adding of CeO2 in Al2O3 facilitates the separation of NiO from NiAl2O4.
- •
The optimal CeO2 content of 60 wt.% improves bio-syngas methanation performances.
- •
Increasing CeO2 content restrains the formation of carbon deposition.
