【 摘 要 】

Due to overuse of fossil fuels, renewable energy resources are of great importance. One of the alternate energy resources could be the agriculture waste or biomass. Biomass pyrolysis not only produces syngas but also produces bio-char and activated carbon. In the present work, pyrolysis of soybean husk was carried out in a fluidized bed, which resulted in fast pyrolysis. The particles bed was fluidized with nitrogen at isothermal conditions. After a specified time, two different conditions of rapid quenching and without quenching were observed for bio-char and bio-oil yield. 250 μm particle size samples were used in the experiments. A material balance was done to determine the incondensable volatiles for each experiment. 83 % bio-oil and 16 % bio-char were obtained at 1000°C. However, at lower temperatures, more bio-char yields were obtained. Therefore, it can be concluded that according to the requirement of the product from soybean husk (bio-oil or bio-char) pyrolysis temperature can be maintained high or low.
