Modelling of Trickle Bed Reactors

One of the most common reactors employed to treat continuously three phase systems (gas-liquid-solid) is the Trickle Bed Reactor. It consists of a column with a fixed bed of catalyst particles through which liquid flows in the form of films, droplets and rivulets. Gas moves cocurrently; sometimes counter-current flows are also used. Usually one reactant is introduced in the liquid phase and the other in the gas phase.
