Abstract:
Biomass gasification is considered one of the most promising technologies for delivering renewable energy. However, tar formation in the gasifiers is one of the main challenges. Ni based catalysts are proven as one of the most effective transition metal catalysts in biomass gasification for tar cracking and reforming. Alumina supported Ni, Pt-Ni, Ru-Ni, Re-Ni and Rh-Ni catalysts were tested for their activity in Reactive Flash Volatilisation (RFV) of cellulose to produce synthesis gas in 50 ms reaction time. RFV is a catalytic gasification process which utilises high carbon space velocity and mass flow rate, with oxygen and steam as gasification agents. Re-Ni, Rh-Ni and Ru-Ni supported catalysts showed higher gasification efficiency than the other catalysts, which was due to their higher metal surface area and metal dispersion. Highest gasificiation efficiency was achieved at 750°C with carbon to oxygen ratio of 0.6 and carbon to steam ratio of 1.0, without any oxygen breakthrough.
