循环流化床作为生物质热解液化反应器的实验研究

总结了固体生物质热解液化装置－一套循环流化床反应器冷态实验的结果。以空气为介质，石英砂为床料，着重考察了循环量与气速、储料量、吹风量、吹风口位置及物料间的关系，得出在一定范围内，循环量随操作气速、Ｌ阀吹风量及储料量的增加而增加；随物料密度、粒径的增大和吹风位置的提高而减小。为热态实验寻找到最佳的操作条件和控制手段。对以木粉为物料的生物质热解油的产率和物性进行了分析。

CFB REACTOR FOR BIOMASS FAST PYROLYSIS

This study work illustrated briefly the fluidization characteristics of a CFB reactor,which is designed for the biomass fast pyrolysis. Using air as fluidizing agent and quartz sand as circulating particle, this test focused on the effect of carrier gas velocity, solid inventory, L valve aeration rate, aeration point and the particle material on the solid circulating rate. The results at various operation conditions indicated that the solid circulating rate increases with the increase of the gas velocity, L valve aeration rate, inventory, and decrease of the particle density, particle size and aeration point. The experimental results also provided the optimum operating condition and control methods for hot test. The distribution of the pyrolysis products and the typical properties of wood derived pyrolysis oil were also introduced. [WT5HZ]
