High-loaded nickel-alumina catalyst for direct CO2 hydrogenation into synthetic natural gas (SNG)

- The CO2 methanation performance over a high-loaded Ni-Al catalyst was investigated.
- The Ni-Al mixed oxide exhibits high methanation activity.
- Coprecipitation of metal precursors leads to high surface area mixed oxide.
- Highly loaded and dispersed small Ni nanoparticles were achieved.
- 500 h-lifetime tests confirm the high activity/stability of the nickel-based catalyst.
