This results in a breakthrough behavior at the top of the riser, analogous to a fixed-bed experiment.

WebAdditionally, it is challenging to simulate the adsorption process because the bed height depends on the feedstream fluid characteristics and flowrate and the particle size of the fluidized media is nonuniform (Lin et al., 2015; Yun et al., 2005). Nevertheless, the goal of eliminating and combining steps during downstream processing, up to and ... 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 …
