摘　　要：以花生壳为原料在流化床反应器内进行了快速热解实验。对花生壳的热解过程进行了物料衡算。通过在冷凝器后增加电捕焦油器,考察了热解油收集方式对热解油产率的影响,热解油的收率由40%增加到64%,说明电捕焦油器的使用不仅避免了产品热解油的流失,而且净化了热解燃气。用电能表对热解过程的能耗进行了计量,计算得出花生壳热解耗能在2 304 kJ/kg左右。通过对热解油元素分析和物理性质表征,分析了各级热解油的特征及应用。Experimental researches on fast pyrolysis of peanut shell were performed in a self-manufactured bench-scale fluidized bed reactor at 500℃.Mass balance of pyrolysis reaction was carried out.Influence of collecting ways on bio-oil yield was investigated.Results showed that bio-oil yield raised from 40% to 64% after the electrostatic precipitators（ESP）settled at the end part of the fractional condensers which prevented bio-oil from losing together with produced gas and cleaned the produced gas.Energy consumption of peanut shell pyrolysis was monitored at about 2304kJ/kg with a watt-hour meter.The physical properties and application of bio-oil were discussed by means of analysis instruments.
