Abstract
heat exchanger tubes in bubbling fluidized bed reactors are necessary to remove the reaction heat of exothermal reactions. Vertical internals that mimic the heat exchanger tubes in cold-flow models, proofed to reduce the bubble size and lead to a more even distribution of the bubbles above the cross-section. Another option is to orientate the internals horizontally inside the column. By means of a measurement campaign at a cold-flow model, differences concerning the hydrodynamic behavior between a column with horizontal and vertical internals were investigated and determined. It turned out that the horizontal internals influence the hydrodynamics in a way which is not beneficial concerning the reactor performance due to an accumulation of bubbles below the horizontal internals and preferential pathways of the bubbles between the horizontal internals.
