Today there has been an interest in the discovery a substitute- “green fuels” to replace the fossil fuel for its depleting reserves, continuously increase in price and growing environmental concern. Biomass is the most common renewable energy. Biomass conversed to liquid fuel should be very prospective. The performance of catalyst in biomass liquefaction process is very important. The solid acid catalyst is superior in comparison with liquid acid and the soluble carbonate of alkali metal which can’t be recycled or corrosive. In this work, ZrO2-SiO2 supported solid acid ClO4-/Fe2O3-La2O3 catalysts was prepared using TEOS and zirconium oxychloride as starting material. The catalysts were characterized by means of BET, XRD and FT-Raman. The catalytic liquefaction of straw in water was carried out in an autoclave. The experimental results showed that the ZrO2-SiO2 supported solid acid ClO4-/Fe2O3-La2O3 catalyst has high activity. Moreover, the resident of straw on the reaction were variable under different catalyst loading, molar ratio of straw to water and reaction time.
