This research focuses on the preparation and properties of rice hull ash(RHA). We prepared RHA from combustion of rice husk in the fluidized-bed reactor. The temperature field of the furnace was steady and bellow 850°C to keep SiO 2 amorphous. XRD, BET and SEM were applied in the characterization tests to investigate the effect of flow rate( u ), the higher primary-secondary wind ratio( i ) and relative height of bed material. The optimal combustion condition for preparing RHA was discussed. RHA obtained from rice hull contains abundant amorphous SiO 2 (>90%) and the characterization results of RHA show its potential to be a good catalyst supporter.
