Fixed Bed Reactor - an overview | ScienceDirect Topics

Using a fluidized bed reactor (Fig. 6.3) resolves some of the problems faced with a fixed bed reactor.This particular reactor offers a much more enhanced mass and heat transfer and minimizes temperature gradients throughout the reactor [64].The mass and heat transfer are improved due to better mixing of the catalyst with the fluid, which provides a greater surface area for the reaction to occur.
