Fixed bed vs packed bed reactors
WebA fluidized bed is a packed bed through which fluid flows at such a high velocity that the bed is loosened and the particle-fluid mixture behaves as though it is a fluid. Thus, when … WebA typical plug flow reactor could be a tube packed with some solid material (frequently a catalyst ). Typically these types of reactors are called packed bed reactors or PBR's. Sometimes the tube will be a tube in a shell and tube heat exchanger . When a plug flow model can not be applied, the dispersion model is usually employed. [2] [3]
