细粒流态化分子式:CAS号:性质:细粒流态化是相对于粗粒流态化而言的。Geldart强调颗粒密度和粒度对流态化的影响而将颗粒分为四类,并提出相应的判别标准。A类——平均粒径50~60μm,粒度范围20~100μm,密度ρs<1.4g/cm3;B类——粒径范围40~50μm,密度4g/cm3>ρs>1.4g/cm3。C类——粒径<30μm的颗粒。D类——粒径>600μm。A类颗粒就是通常所说的细粒。细粒流态化操作气速Uf与临界流化速度Umf之比可高达300以上,床层膨胀比较大,床层密度较小,床层处于激烈地湍动和混合状态;两相的概念依然存在,但乳浊相的气速uE远大于umf,一般uE=(3~5)umf;气泡直径Db远大于粗粒床(Db∝dp4),且几乎不随uf的增大而增大;但气泡频率却大于粗粒床,而且在床高方向基本上不聚并;两相的气体交换速率增大;床层的最大稳定气泡直径几乎不随床径而变,因而气体在两相间的分配也大致与床径无关,这显然对放大是有利的。主要应用于要求高转化率和高选择性的催化反应过程,如催化裂化、催化重整等大型生产工艺过程。
