Fluidized bed reactor design and scale-up - ScienceDirect

2013-01-01· The design model is a model based on the two-phase theory of fluidized beds of Toomey and Johnstone (1952), which states that all gas in excess of the minimum fluidization velocity passes through the bed as bubbles. The design model (schematically depicted in Fig. 10.5) is then used to estimate the mass transfer between the two phases.

Fluidized bed reactor - Wikipedia

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
