Fluidized Bed Reactor - an overview | ScienceDirect Topics

Fluidized bed reactors have been studied in several reactor engineering researches for OCM, also quite stable and efficient performance was reported especially in case of reactor operability and safety concerns. Due to the large exothermic of the OCM reaction, a fluidized bed reactor enables an almost isothermal reactor performance in OCM and was therefore the first investigated reactor type.

Fluidized Bed Bioreactors: Fluidized bed bioreactor is comparable to bubble column bioreactor except the top position is expanded to reduce the velocity of the fluid. The design of the fluidized bioreactors (expanded top and narrow reaction column) is such that the solids are retained in the reactor while the liquid flows out (Fig. 19.3A).
