A series of experiments was conducted to study the effect of temperature and feed rate on physicochemical properties and yield of bio-oil. The experiments were performed in a helical screw fluidized bed reactor and about 150-gram palm shell (PS) was pyrolyzed in each run at 275 °C/min heating rate. The first set of experiments was conducted at temperature ranging from 400 to 650 °C without using any inert gas for fluidization. While the second set of experiments were performed at feed rates ranging from 3 to 25 g/min in order to investigate the effects of feed rate on pyrolytic products. Results showed that the bio-oil yield was increased with the increase in temperature and feed rate due to the enhanced biomass volatilization. In a similar vein to this, a greater extent in oxygenates cracking was also noted in the bio-oil. A maximum liquid yield of about 72.84 wt% was obtained at 500 °C, while 72.92 wt% liquid yield was obtained with 25 g/min feed rate. The HHV of bio-oil was also increased from 38.52 to 43.13 MJ/kg when pyrolysis temperature was increased from 400 to 650 °C.

进行了一系列实验以研究温度和进料速率对生物油的理化性质和产量的影响。实验在螺旋螺杆流化床反应器中进行，每次运行中以 275°C/分钟的加热速率热解约 150 克棕榈壳 (PS)。第一组实验在 400 至 650 °C 的温度范围内进行，不使用任何惰性气体进行流化。而第二组实验以 3 至 25 g/min 的进料速率进行，以研究进料速率对热解产物的影响。结果表明，由于生物质挥发的增加，生物油产量随着温度和进料速率的增加而增加。与此类似，在生物油中也注意到更大程度的含氧化合物裂解。在 500 °C 下获得了约 72.84 wt% 的最大液体产率，而在 25 g/min 进料速率下获得了 72.92 wt% 的液体产率。当热解温度从 400°C 增加到 650°C 时，生物油的 HHV 也从 38.52 增加到 43.13 MJ/kg。
