“…30,[34][35][36][37][38] However, it is well-stablished that the liquid recirculation rate plays an important role in mass transfer, particularly when a Venturi injector is used. 17,18,20 In this work, the liquid passing through the Venturi ejector (Q L ) induced an air suction (Q G ) from 0.2 to 0.5 L min −1 , which was introduced directly into the culture medium. Undoubtedly, the aeration in the JLR was the lowest of the three reactors.…”

BACKGROUNDThe development of processes for transforming vegetable oils into useful products has received increasing attention in the biotechnological field. The reactor used for this purpose should meet adequate mass transfer, mixing and oil dispersion conditions. In this work comprehensive research into the use of a jet‐loop reactor as a potential alternative to airlift and stirred tank reactors was conducted in presence of avocado oil in a water‐air system. Additionally, the assessment of the jet‐loop for biomass growth in presence of oil was performed.RESULTSThe increase of avocado oil from 1 to 5 % v/v resulted in a reduction in the performance of the three reactors. Despite the airlift reactor having the lowest power input, it exhibited the worst performance in terms of mass transfer, mixing and oil dispersion. The estimation of the energetic oxygen transfer efficiency (Kg O2 KW‐1 h‐1) allowed the determination that the jet‐loop reactor was superior to the stirred tank. This superiority was attributed to the low values of the mixing time and oil droplet diameter observed in the jet‐loop reactor. Finally, all these parameters had a positive impact on the growth of Wautersia eutropha in the jet‐loop reactor compared with the other two reactors.CONCLUSIONSThe results showed that the jet‐loop reactor presented superior performance in most cases compared to the stirred tank and airlift reactors. Particularly, the jet‐loop exhibits an interesting potential to reduce the size of the avocado oil droplets, which could lead to a significative increase in the growth rate of Wautersia eutropha.This article is protected by copyright.

The multistage internal airlift loop reactor (MIALR) has shown promising application prospects in gas–liquid–solid reaction systems. However, traditional MIALRs have a global circulation with strong interstage liquid-phase exchange. This paper proposes a staggered multistage internal airlift loop reactor (SMIALR) that incorporates special guide elements to create a staggered flow. Both experiments and computational fluid dynamics-population balance model simulations were conducted to investigate the hydrodynamic performances of MIALR and SMIALR. The results demonstrate that SMIALR exhibits a local circulation at each stage. Bubbles have a longer residence time in SMIALR, resulting in a 28.35%–55.54% increase in gas holdup and a 7.27%–13.69% increase in volumetric mass transfer coefficient. The gas–liquid mass transfer coefficient of SMIALR was improved by increasing the gas–liquid interfacial area. Additionally, the radial distribution of solids was found to be more uniform. This study offers insights for optimizing MIALR and provides a theoretical foundation for the design and scale-up of SMIALR.
