Catalytic gasification of lignin with Ni/Al2O3-SiO2 in sub/supercritical water

- Supercritical water gasification with Ni/Al2O3-SiO2 provides economically potential way to convert lignin into gaseous fuels.
- Ni/Al2O3-SiO2 shows the characteristic peaks of crystalline NiO, NiSi, AlNi3 and SiO2.
- A kinetic model was developed and the mechanism was discussed.
