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 degrees C and the highest liquid product yield was obtained at 475 degrees C. Liquid products obtained under the most suitable conditions were characterized by physical properties, elemental analysis, GCV, FT-IR, (1)H NMR analysis and distillation. The empirical formula of the bio-oil with heating value of 23.5MJ/kg was established as CH(1.68)O(0.557)N(0.012). 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.
以甘蔗渣形式存在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，以确定终温、扫气流量和进料尺寸对产物收率的影响。研究的终温范围在 375 到 575 摄氏度之间，在 475 摄氏度时获得了最高的液体产物收率。在最适宜的条件下得到的液体产物通过物理性质、元素分析、GCV、FT-IR、（1）H NMR 分析和蒸馏进行了表征。热值为 23.5MJ/kg 的生物油的经验公式为 CH(1.68)O(0.557)N(0.012)。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收率更高，作为燃料具有更好的物理化学性质。这些发现表明，固定床火管加热热解是从生物质固体废弃物生产生物油的一种很好的选择。
