摘　　要：使用自主研发的流化床热解反应器对生物质热解制油进行实验研究,通过对不同实验温度450、500、525、550、580、610℃下得到的目标产物进行分析,得到了反应温度对生物油产率的影响规律。实验表明:550℃时,最大液体产率为42.5%(质量);实验得到的不可冷凝气体的组分以CO、CO2、CH4和H2为主,气相产物产率约为37.7%(质量)。在实验基础上,利用Aspen Plus流程模拟软件,建立了生物质热解制油工艺模拟流程,模拟分析了热解温度对生物油产率的影响,结果表明该模型能准确模拟实际热解过程,具有较好的适用性和可靠性。The experimental research of biomass pyrolysis for production of bio-oil is performed with a fluidized bed reactor designed by ourselves. By analysis of desired products collected at different temperature 450, 500, 525, 550, 580, 610℃, influence of reaction temperature on the yield of bio-oil is investigated in this paper. The results show that the highest yield of bio-oil is 42.5%（mass） received around 550℃, while gas yield is 37.7%（mass）, gas components are mainly CO, CO2, CH4, H2. On the basis of the experiment, using Aspen Plus software for process simulation a biomass fast pyrolysis model for production of bio-oil is set up, the effects of temperature on bio-oil yield is simulatedly analyzed. The results show that the pyrolysis process is simulated exactly, the model is proved applicable and reliable.
