摘　　要：以空气-水-石英砂体系为对象,研究了费托合成浆态床反应器中表观气速、平均淤浆浓度、床层轴向位置等因素对气含率、固体浓度轴向分布和粒径分布的影响,并通过实验得出了气含率与操作变量之间的关联式。The gas holdup,axial solid concentration distribution and particle size distribution in a slurry bubble column reactor were investigated experimentally by using air as the gas phase,tap water as the liquid phase,and quartz sands as the solid phase.The effects of superficial gas velocity,average solid concentration and axial location were discussed.A correlation formula between gas holdup and operating parameters has been obtained.

关 键 词：浆态床反应器 气含率 固体浓度轴向分布 粒径分布
