5.5 Bubbling Fluidized-bed Combustion (BFBC) Boilers. oxygen was almost consumed at GHSV of 1800 h- 1 in the fluidized-bed reactor. The fluidized OCM reaction requires longer contact time for the consumption of oxygen than in the fixed-bed reaction. From this results, it can be seen that the diffusion of reactants and products between the

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 velocities to suspend the solid and cause it to behave as though it were a fluid.

Fluidized Bed Reactor - an overview | ScienceDirect Topics

Fluidized-bed reactors. Fluidized-bed reactors are theoretically an excellent reactor type choice for highly exothermic reactions, such as the FT reaction. Fluidized-bed reactors offer a much higher efficiency in heat exchange, compared to fixed beds, and better temperature control, due to the turbulent gas flow and rapid circulation.
