摘要：

The effects of certain pertinent parameters such as gas and liquid flow rates and nozzle position on the behavior of a down flow jet loop bioreactor (DJB) have been studied. The mean residence times of gas and liquid phases and the gas hold-up within the bioreactor have been measured. A correlation has been presented for the gas hold-up. In addition, the overall volumetric mass transfer coefficient, and the influence of the gas flow rate and the position of the nozzle inside the draft tube on the latter has been determined and a correlation has been derived. The liquid residence time distribution (RTD) within the bioreactor has been studied by tracer analysis and the mixing time was calculated using the RTD results. (C) 2001 Elsevier Science B.V.
