Introduction

Airlift reactors are attractive for slow reactions since they consist of recycle streams that allow for a lager residence time within a small reactor volume when compared to [slurry] bubble columns. They are also attractive in processes where a certain degree of agitation is required without the use of mechanical stirrers due to the nature of the reactants handled, such as in the cultivation of biological organisms. In the current investigation, we are interested in studying the effect of low-frequency vibrations on the gas holdup and volumetric mass transfer coefficient in an internal loop airlift column reactor. Results obtained from this study would be compared with those obtained from a circular channel monolith loop reactor, a square channel monolith loop reactor and a bubble column reactor.
