Fast steam pyrolysis of rice husk was performed in a fluidized bed reactor. The pyrolysis conditions of the feed rate of rice husk at 12 kg/h, the feed rate of steam at 9 kg/h, and the vapor residence time of 0.62 sec were kept constant, and the pyrolysis temperature was varied from 430 to 630°C to investigate its influences on properties of the produced gas, liquid bio-oil, and solid char. Results showed that the components in the gaseous product (including CO2, CO, CH4, H2, etc.) were evidently affected by the temperature. Fourier transform infrared analysis was employed to research into the changing trend of the organic groups existing in the produced chars and bio-oils. Furthermore, detailed components in the bio-oils obtained under different temperatures were determined by gas chromatography-mass spectrometry analysis.
