将甘蔗渣形式的农业废弃物在固定床火管加热反应器中在不同的热解条件下进行热解，以确定最终温度、吹扫气流量和进料尺寸对产品产量的影响。最终研究的温度范围为 375 至 575°C，最高液体产物产率在 475°C 时获得。在最合适的条件下获得的液体产物通过物理性质、元素分析、GCV、FT-IR、1H NMR分析和蒸馏进行表征。建立了热值为23.5MJ/kg生物油的经验公式为CH1.68O0.557N0.012。与其他方法的比较表明，这种更简单的反应器系统的液体产物产率更高，并且作为燃料具有更好的物理化学性质。这些研究结果表明，固定床火管加热热解是生物质固体废物生产生物油的一个不错的选择。
Agricultural waste in the form of sugarcane bagasse was pyrolyzed in a fixed-bed fire-tube heating reactor under different pyrolysis conditions to determine the role of final temperature, sweeping gas flow rate and feed size on the product yields. Final temperature range studied was between 375 and 575°C and the highest liquid product yield was obtained at 475°C. Liquid products obtained under the most suitable conditions were characterized by physical properties, elemental analysis, GCV, FT-IR,1H NMR analysis and distillation. The empirical formula of the bio-oil with heating value of 23.5MJ/kg was established as CH1.68O0.557N0.012. Comparison with other approaches showed that the liquid product yield by this simpler reactor system was higher with better physico-chemical properties as fuel. These findings show that fixed-bed fire-tube heating pyrolysis is a good option for production of bio-oils from biomass solid wastes.
