A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.This is usually achieved by the introduction of pressurized fluid through the particulate medium. A laboratory scale fluidized bed reactor was designed and fabricated successfully. In a fluidized bed reactor, the solid material in the form of fine particles is contained in a vertical cylindrical vessel. Fluidized‐bed processes for heterogeneous catalytic gas‐phase reactions, for the polymerization of olefins, for homogenous gas‐phase reactions, gas–solid reactions and applications in biotechnology are described in detail.
