Pyrolysis experiments were performed at pyrolysis temperature between 400 and 600&amp;deg;C with a constant heating rate of 60&amp;deg;Cmin and particle sizes of 0.601.18 mm. The optimum process conditions for maximum liquid yield from the rice husk pyrolysis in a fixed bed reactor were also identified. The highest liquid yield was obtained at a pyrolysis temperature of 500&amp;deg;C, particle size of 1.181.80 mm, with a heating rate of 60&amp;deg;Cmin in a 300 mm length reactor. The obtained yield of, liquid, gas and solid were found be in the range of 22.5731.78 , 27.7542.26 and 34.1742.52 (all weight basics) respectively at different pyrolysis conditions. The results indicate that the effects of pyrolysis temperature and particle size on the pyrolysis yield are more significant than that of heating rate and reactor length. The functional groups and chemical compositions present in the liquid obtained at optimum conditions were identified by Fourier TransformInfrared (FTIR) spectroscopy and Gas Chromatography Mass Spectroscopy (GCMS) analysis respectively.</abstract> <index>Open Science Index 32, 2009</index> </article>
