Overview: Fluidized beds have gained prominence in many process in- dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids. Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as in quenching or annealing). Other operations involve chemical reactions including the cata- lytic cracking of hydrocarbons, the manufacture of acry10nitrite and phthalic anhydride, the roasting of metallurgical ores, and the regeneration
