WebFluidized beds are commonly used to produce pyrolytic carbon. 3,7–13 Production using tumbling beds and stationary beds has also been investigated. Tumbling bed reactors … 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.

Fluidized beds overview : Fundamentals of fluidized beds
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 … WebFuel quality, thermophysical properties, and transport coefficients.
