Typical packed bed reactors consist of a chamber, such as a tube or channel that contains catalyst particles or pellets, and a liquid that flows through the catalyst.

Another factor in addition to the packing shape and surface area that affects the performance of random or structured packing is liquid and vapor distribution entering the packed bed.

Used to calculate the flow of a liquid through a packed bed of solids, the equation was first proposed by Kozeny in 1927 and later modified by Philip Carman.

The performance of a packed bed is highly dependent on the flow of material through it, which in turn is dependent on the packing and how the flow is managed.

Matros developed a catalytic reactor with periodic changes of direction of flow rate in packed bed of catalyst ( named in literature as reverse process or Matros Reactor ).
29.
At higher feed flow rates, smaller-sized particles at the lower layer of the packed bed are able to be screened at designated apertures and remaining small-sized particles adhere to larger particles.

The Ergun equation can be used to predict the pressure drop along the length of a packed bed given the fluid velocity, the packing size, and the viscosity and density of the fluid.
