## Abstract The influences of aliphatic alcohols (C~n~H~2n+1~OH, __n__ = 1–4) and their concentrations (0–1 vol.‐%) on gas holdup, liquid circulation velocity, mixing time, and overall volumetric gas‐liquid oxygen mass transfer coefficient were considered in a split‐cylinder airlift reactor sparged

The hydrodynamics and mass transfer, specifically the effects of gas velocity and the presence and type of solids on the gas hold-up and volumetric mass transfer coefficient, were studied on a lab-scale airlift reactor with internal draft tube. Basalt particles and biofilmcoated particles were used
## Abstract Effects of various concentrations (0–5 ppm) of anionic (sodium dodecyl sulfate, SDS) and non‐ionic (Tween‐80 and Triton X‐405) surfactants on gas hold‐up and gas–liquid mass transfer in a split‐cylinder airlift reactor are reported for air–water. Surfactants were found to strongly enhan
## Abstract The aim of this work was to investigate an influence of different alcohols on the behavior of a draft tube airlift reactor. The main hydrodynamic and mass transfer parameters in 1 wt % aqueous solutions of five aliphatic alcohols were examined. The results showed that alcohol addition e
