Abstract This work analyses the influence of different experimental conditions over important hydrodynamic parameters of a bubble column reactor, such as bubble size distribution, gas hold-up and the gas–liquid interfacial area. The influence of gas flow-rate (18–40 L h–1) and reagent concentration (0–0.5 mol L–1) in the liquid phase upon these hydrodynamic parameters have been studied. The influence of experiment time must also be taken into account due to non-steady-state regime. Under these considerations, the chemical absorption rate changes throughout time, and it produces important changes upon the global absorption process, due to modifications in the gas–liquid interfacial area. The presence of a fast reaction in the liquid bulk has the highest influence upon interfacial area.

Slurry Bubble Column Reactor

Three-phase slurry bubble column reactor owns a wide application area. This review focuses on the hydrodynamics of the reactor from the findings of published studies, which includes the flow regimes, gas holdup, bubble size and distribution and mass transfer coefficients. The factors affecting each parameter and the status of the research are discussed, and the development of slurry bubble column reactor has also been prospected. At present, the experimental data that can be used in the industrial application is not accurate, an enlargement of the reactor is still a difficult problem, it remains to be further exploring in close to real environment.
