Abstract: Bio-oil from rice husk was prepared by fast pyrolysis. The effect of feed rate on the reaction parameters of fluidized reactor was investigated. With increasing feed rate (4 kg/h to 5 kg/h) it was found that the pressure difference and pyrolysis gas were also increased, while reaction temperature decreased. These results indicated that secondly-cracking reaction was increased in pyrolytic products. The components of product were analysized by GC-MS. Thermal stability of bio-oil was determined by TG-DSC. The major fuel properties of bio-oil were characterized.

Key words: rice husk, pyrolysis, bio-oil
