摘　　要：本文在热态条件下,研究了鼓泡浆液反应器的气含率,反应器直径为0.098 m,物系组成为氮气-液体石腊-石英砂。考察了气速、压力、温度、静床高及固体引入等因素对气含率的影响。对于53 μm 粒子的三相浆态体系,气含率与表观气速关系式为ε_G=0.053u_G^(1.2)。In this paper,gas holdup was investigated in a hot-flow bubble column slurry reactor(BCSR).The ID of bubble column is 0.098m,and the three-phase system consists of nitrogen,paraffin liquid,and quartz sand.The effect of various factors on gas holdup has been studied.In the three-phase system containing 53 μm particles,the dependence of gas holdup on gas velocity is ε_G=0.053u_G^(1.2).
