Fast pyrolysis is considered an emerging technology for biomass conversion into liquid oil. In this paper, the conversion of waste from Isoberlina doka tree processing into bio-oil using a bench-scale fixed bed reactor with a fluidized behavior within the bed zone has been investigated at temperatures of 400–500 °C and particle size ranges of < 0.5 and 0.5–1 mm. Reactor with the total height of 140 mm consisting of three zones with gas inlet diameter of 10 mm, reaction zone diameter of 70 mm, outlet diameter of 15 mm and a coupled detachable inlet with a diameter 15 mm for biomass loading was used for experimentation. Nitrogen was used as the carrier gas, and the products were biochar, bio-oil and non-condensable gas. Thermogravimetric and derivative thermal analysis (TG/DTA) was carried out in order to understand the thermal behavior of wood particles. Bio-oil produced was analyzed using the gas chromatography mass spectrometry and the Fourier transform infra-red spectrophotometry methodologies. TG/DTA analysis revealed an initial 30.639% mass loss which correlates to hardwood thermal characteristics. Bio-oil yield from bench-scale pyrolysis increased with increasing temperature. A maximum bio-oil yield of 49.84 wt % was observed at the particle size range of 0.5–1 mm, bed temperature of 500 °C and time of 30 min. Volatile generation was at the peak of 54.54% (0.002655 kg/min). However, changes in the chemical composition and functional groups of bio-oil with temperature of production suited it for different usage purposes.

快速热解被认为是将生物质转化为液态油的新兴技术。本文介绍了伊索贝琳娜·多卡（Isoberlina doka）产生的废物转化已经研究了使用台式固定床反应器在床区内流化行为将树木加工成生物油的行为，其温度为400-500°C，粒径范围<0.5和0.5-1 mm。实验使用了总高度为140 mm的反应器，该反应器由三个区域组成，三个区域的进气口直径为10 mm，反应区域直径为70 mm，出口直径为15 mm，以及一个耦合的可拆卸入口，直径为15 mm，用于装载生物质。氮气用作载气，产品为生物炭，生物油和不凝性气体。为了了解木材颗粒的热行为，进行了热重分析和微分热分析（TG / DTA）。使用气相色谱质谱法和傅立叶变换红外分光光度法对产生的生物油进行分析。TG / DTA分析显示初始质量损失为30.639％，这与硬木的热特性有关。台式热解的生物油产量随温度的升高而增加。在粒径范围为0.5–1 mm，床温为500°C，时间为30分钟时，观察到最大生物油产率为49.84 wt％。挥发物生成达到峰值54.54％（0.002655 kg / min）。然而，生物油的化学组成和官能团随生产温度的变化使其适合于不同的用途。台式热解的生物油产量随温度的升高而增加。在粒径范围为0.5–1 mm，床温为500°C，时间为30分钟时，观察到最大生物油产率为49.84 wt％。挥发物生成达到峰值54.54％（0.002655 kg / min）。然而，生物油的化学组成和官能团随生产温度的变化使其适合于不同的用途。台式热解的生物油产量随温度的升高而增加。在粒径范围为0.5–1 mm，床温为500°C，时间为30分钟时，观察到最大生物油产率为49.84 wt％。挥发物生成达到峰值54.54％（0.002655 kg / min）。然而，生物油的化学组成和官能团随生产温度的变化使其适合于不同的用途。
