3.2 Justification for Proposed Work 3.2.1 Theory Fluidization is a process where solid-state particles are moved into a fluid-like state by means of suspension from either a gas or a liquid. This is accomplished by passing an upward flow of either a gas or liquid up through a fixed bed of small solid particles. Fluidized beds are used in industry for a number of reasons. First, they are an easily controlled process due to smooth, liquid-like flow of the particles. Also, compared to other methods, the rates of mass and heat transfer are high, providing good contact. Furthermore, since the solids are mixed so quickly, the fluidized bed represents near isothermal conditions, which leads to a very reliable process.
