To produce bio-oil from rice straw, a bench scale plant equipped with a fluidized-bed and a char removal system is applied. The influence of reaction temperature on the production of bio-oil and the efficiency of a char-separating system were studied. To elucidate the temperature dependence on the production of bio-oil, experiments were conducted at 400° and 600°C with a feed rate of ∼ 1.3 kg/hr. Mass balance was established in each experiment. Analysis of product gas and oil was conducted using GC and GC-MS system. Char removal system was composed of a cyclone and a hot filter. After every experiment, the particle distribution of each char and the content of solid in bio-oil to demonstrate the efficiency of the char removal system were examined. In the experiments, bio-oil nearly free of alkali metals could be obtained, and optimum reaction temperature for the production of bio-oil was between 410°-510°C. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
