In-situ catalytic conversion of tar using rice husk char-supported nickel-iron catalysts for biomass pyrolysis/gasification

- Biomass tar could be in-situ converted by rice husk (RH) char-supported Ni-Fe catalysts;.
- 92.3% and 93% of tar conversion efficiencies were obtained using Ni-Fe char and Ni-char, respectively;.
- Partial metal oxides were in-situ deoxidized into metallic states;.
- RH char-supported catalysts can be regenerated into SiO2-based catalysts or gasified into syngas.
