Design of fluidized bed reactor
WebFeb 21, 2016 · A fluidized bed reactor is used to produce a variety of products. In fuel industry, a fluidized bed reactor is used to produce gasolines, propane, butane, and propylene (Washington University, … WebA 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 heterogeneous mixture of fluid and solid that can be represented by a single bulk density.
