WebApr 2, 2024 · Fluidized Bed Reactors: Reactions that require a significant amount of contact between the reactants and the catalyst are best carried out in fluidized bed reactors. The catalyst is suspended in a fluid in a fluidized bed reactor, and the reactants are moved through the bed. WebMoving bed reactors are catalytic reactors in which the catalyst moves through the reactor along with the reactants. They are open systems and operate at a steady state. The animation below shows the operation of a …
