Abstract: The catalyst of Cl /Fe O was prepared by hydrothermal synthesis. In this paper rice husk
2 3
pubescens and corn stalk were liquefied by using Cl /Fe O as catalyst. The influences of the amount of
2 3
the catalyst reaction temperature and reaction time on the catalyst activity for the biomass conversion
were investigated and the life test of the catalyst was carried out. The results showed that Cl /Fe O
2 3
could be used as the catalyst in the liquefaction of biomass. The best operation conditions were reaction
temperature of 300 reaction time of 3 hours and the amount of the catalyst of 4% (wt%). The catalyst
was re-used 5 times and the conversion of corn stalk was up to 90%. All the above results showed that
the catalyst had good activity and stability.
