在固定床管式反应器中对木屑进行了热解。考察了裂解温度、吹扫气流量、冷凝温度和升温速率对产物收率的影响。在不同的热解条件下，所获得的炭、气体和生物油的产率分别在20和27、36和45以及33和45重量%之间。根据在本研究条件下获得的结果，热解温度、吹扫气体流速和加热速率对产率的影响比冷凝温度的影响更显著。通过元素分析和热分析对最佳操作条件下得到的热解生物油和半焦的化学特征进行了鉴定。使用色谱和光谱技术分析生物油。
Sawdust was pyrolyzed in a fixed-bed tubular reactor. The roles of the pyrolysis temperature, sweep gas flow rate, condensation temperature, and heating rate in the yields of the products were investigated. The obtained char, gas, and bio-oil yields ranged between 20 and 27, 36 and 45, and 33 and 45 wt %, respectively, at different pyrolysis conditions. According to the results obtained under the conditions of this study, the effects of the pyrolysis temperature, sweep gas flow rate, and heating rate on the yields are more significant than the effect of the condensation temperature. The chemical characteristics of the pyrolysis bio-oil and char obtained under optimal operational conditions were identified by elemental and calorific analyses. The bio-oil was analyzed using chromatographic and spectroscopic techniques.
