網頁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.
