Jet loop reactors as a versatile reactor set up - Intensifying catalytic reactions: A review
TL;DR: In this paper, the authors convey a thorough overview about the jet loop reactor technique and elucide the operation principle of the reactor type, with particular focus on the enhancement of catalytic reactions subdivided in homogenously, heterogeneously and biocatalyzed conversions.

Gas-Liquid mass transfer in a down flow jet loop reactor
M. Velan,T.K. Ramanujam +1 more
TL;DR: In this article, the authors measured the volumetric mass transfer coefficient in a down flow jet loop reactor with Newtonian and non-Newtonian systems, and found that volumeetric mass transferred coefficient increase in gas and liquid flow rates, and nozzle diameter.
Journal ArticleDOI
Characterization of gas transfer and mixing in a bubble column equipped with a rubber membrane diffuser
TL;DR: The design of the bottom plate of the reactor enabled us to optimize the aeration by changing the tension of the membrane, and the authors thereby achieved mass transfer coefficients higher than those previously reported in bubble columns.

Hydrodynamic characteristics of a spinning sparger, external loop airlift bioreactor
Randall D. Fraser,Gordon A. Hill +1 more
TL;DR: In this paper, a flat plate, spinning sparger had six orifices and was located below the downcomer connection to prevent the generation of a high shear environment inside the bulk medium.

Gas holdup and overall volumetric mass transfer coefficient in a modified reversed flow jet loop reactor
K. Yagna Prasad,T. K. Ramanujam +1 more
TL;DR: In this article, a modified reversed flow jet loop reactor with the liquid outlet at the top of the reactor was used to determine the gas holdup and overall volumetric mass transfer coefficient in the air-water system.

Coalescence of gas bubbles in aqueous solutions of inorganic electrolytes
G. Marrucci,Luigi Nicodemo +1 more
TL;DR: In this paper, a discussion is made of the coalescence phenomena which occur near the distributor and a correlation is attempted which relates the average bubble diameter to the gas flow rate and to a group, G, of the electrolyte properties.
