摘要: The effects of the unaerated liquid height (0  h 0.20 m), superficial gas velocity (0.02 UG 0.18 ms 1) and downcomer-to-riser cross-sectional area ratio (0.11 Ad/ Ar 0.53) on hydrodynamic characteristics, such as holdups in riser downcomer, circulation time, mixing an external-loop airlift reactor were systematically investigated. height, important parameters which strongly affected characteristics reactor. As increased, time decreased whereas increased.
