Fluidized bed chromatography
WebIntroduction. As a fluid passes through a packed bed it experiences pressure loss due to factors such as friction. The relationships required to predict the pressure drop for a fluid flowing through a packed bed have been known for some time, with Darcy observing in 1896 that the laminar flow of water through a bed of sand was governed by the following … WebIn recent years, fluidized-bed adsorption has been used as an alternative method to conventional packed-bed column chromatography for protein purification (1–8). This technology allows the recovery of high-value …

A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles. The resulting medium then has … See more A fluidized bed consists of fluid-solid mixture that exhibits fluid-like properties. As such, the upper surface of the bed is relatively horizontal, which is analogous to hydrostatic behavior. The bed can be considered to be a … See more In 1922, Fritz Winkler made the first industrial application of fluidization in a reactor for a coal gasification process.
