Packed bed reactors, also known as fixed bed reactors, are often used for catalytic processes. Pictured below is a fixed bed reactor used in a synthetic process. . Trickle bed reactors are solid-liquid-gas contacting devices wherein a liquid stream flows downward over a bed of catalyst with pressure difference serving as the driving force.

What is Chemical Reactor?

A tubular reactor can often be a packed bed. In this case, the tube or channel contains particles or pellets, usually a solid catalyst. The reactants, in liquid or gas phase, are pumped through the catalyst bed. A chemical reactor may also be a fluidized bed.

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