Flow through Packed Beds and Fluidized Beds

Flow through Packed Beds and Fluidized Beds

A 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 a bed of particles is fluidized, the entire bed can be transported like a fluid, if desired. Both gas and liquid flows can be used to fluidize a bed .

Fixed Bed Reactors; In a fixed-bed reactor, the reagent flows over a stationary bed of packed catalyst (Towler and Sinnott, 2013). This is the most common type of reactor used for heterogeneous catalysis as long as the catalyst does not require continuous regeneration and the reaction mixture does not require high agitation (Towler, 2012).

The advantage of the packed-bed reactor is that for most reactions it gives the highest conversion per weight of catalyst of any catalytic reactor. Another type of catalytic reactor in common use is the fluidized-bed reactor, which is analogous to the CSTR in that its contents, though heterogeneous, are well mixed, resulting in an even .
