Fixed beds and fluidized beds
WebA 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 … WebA fluidized bed is typically made of a column which is containing the solid to fluidize (mostly powders, sometimes granules <6 mm diameter) and which has at its base a distribution plate that allows to blow a gas through the bed of particles. On top of the column, a gas exhaust is installed.
