文摘
- •
Co, Ni-based catalysts were oxidized in steam reforming of acetone at low temperatures.
- •
Ni catalyst was reduced and active for reforming of acetone in H2 at low temperatures.
- •
The reaction pathway was strongly influenced by reduction of the Co-Ni surface.
- •
Steam reforming of acetone was not possible at low temperatures over the Ni catalyst.
- •
The fragments of acetone activation were hydrogenated to CH4 at low temperatures.
