A bubble column reactor is a chemical reactor that belongs to the general class of multiphase reactors, which consists of three main categories: trickle bed reactor (fixed or packed bed), fluidized bed reactor, and bubble column reactor. [ 1] A bubble column reactor is a very simple device consisting of a vertical vessel filled with water with ...
Fluidization. Fluidization (or fluidisation) is a process similar to liquefaction whereby a granular material is converted from a static solid -like state to a dynamic fluid -like state. This process occurs when a fluid ( liquid or gas) is passed up through the granular material. When a gas flow is introduced through the bottom of a bed of ...
