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 many properties and characteristics of normal fluids, such as the ability to free-flow … WebFluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This allows for extensive mixing in all directions. A result of the mixing is excellent temperature stability and …

WebJan 1, 2000 · Expanded or fluidized bed chromatography is a stable liquid-solid fluidized bed. Here, adsorbents are fluidized, and the flow of the mobile phase is directed upwards with minimum back-mixing [37, 38]. 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 …

(Roy et al., 2005; Sonnenfeld and Thömmes, 2007). It uses a fluidized bed but the hydrodynamic properties of the chromatography medium are such that it behaves like a packed bed (i.e. there is no back mixing of the beads).

WebThe protein binding principles in EBA are the same as in classical column chromatography and the common ion-exchange, hydrophobic interaction and affinity chromatography ligands can be used. After the adsorption step is complete, the fluidized bed is washed to flush out any remaining particulates.
