Design and Simulation of Bubble Column Reactors - Springer

Bubble column reactors (BCR) are contactors in which a discontinuous gas phase moves in the form of bubbles relative to a continuous liquid phase. In the liquid, a reactive solid or catalyst may be fluidized. BCR can be single staged or multi staged, batch or continuous with regard to the liquid (or slurry) phase.

Abstract. Gas sparged bubble columns and slurry reactors are used extensively in the production of fuels, fuel additives and chemicals. Their performance (e.g., selectivity, conversion, etc.) depends to a large extent on the degree of backmixing of the liquid phase.
