Trickle Bed

Equipment Design

The animation below shows the basic operation of a trickle bed reactor, which contains a fixed bed of catalyst. Liquid reactants (green arrows) and gas phase reactants (yellow arrows) continuously enter the reactor and flow through the catalyst bed. The liquid and gas reactants react at the catalyst, and the products are removed continuously.



  • Can be used for three phase reactions
  • Hot spots may develop
  • Channeling may occur, leading to inefficiencies
