, 2001 介绍了以循环流化床反应器为主体的固体生物质热解液化装置，实验过程，实验结果分析，通过对气体产物的比较及油产物一般物性和油成分的分析，得出如下结论：1）较高的温度和较和的停留时间会降低的产率，生产过多的不凝气，过低的温度和加热速度导致严重的碳化，同样会降低油产率，本实验的最高油产率可达63％，2）生物质热解油品的物性特点主要包括水分量较高,pH值较低，粘度变化范围很大，热值与化石燃料相比为低，并且油品中因含氧量很高而极不稳定，油品的组成成分非常复杂，烷烃和非烃占据了相当的比例，芳烃和沥青质含量相对较少，3）

, 1983 众所周知,流化床中气体一颗粒的传递过程和反应过程,主要发生在分布板区。而浅层流化床正具备了分布板区的许多优点,它在涉及热过程的领域中,已经显示了广阔的应用前景。 为了考察浅层床中气体一颗粒间的传递特征,本文从气体一颗粒传热入手,采用热响应的实验技术,测定了气-固系浅流化床(L/D_T=0.045～0.17)内空气-海砂的表观传热系数,同时求算了相应的浓相区传热系数,并表述了传热系数随床深的变化趋势。从实用角度,本研究最终将表明,在较浅的颗粒床层中,能给出较大的传热速率但床层压降较小 ...
