CO2 hydrogenation into CH4 on NiHNaUSY zeolites

- CO2 methanation over Ni supported HNaUSY zeolite catalysts.
- Doping of the Ni-zeolite catalysts with Ce.
- Significant CO2 conversions and CH4 selectivities achieved with Ni catalysts.
- Ce leads to a further enhancement of the catalysts performance.
- No important deactivation observed after 10 h of reaction at 400 °C.
