A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles.

Fluidized beds are granular systems of solid-particles subjected to a vertical upward flow of fluid. From: Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2018

Explore the fundamentals of fluidized beds, from understanding the basics to troubleshooting common issues. Learn about fluidization, minimum fluidization velocity, pressure drop, and versatile applications in powder technology, and more.

A 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 passed through a solid granular material (usually a catalyst ) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

2010年9月7日 · A fluidized bed is a state of a two-phase mixture of particulate solid material and fluid, which is widely used in many modern technologies for efficient implementation of various physical and chemical processes.

Fast Fluidized Bed The fast fluidization occurs as a result of continuing increasing in operating velocity beyond that required at turbulent fluidization, a critical velocity, commonly called the transport velocity (Utr), will be reached where a significant particle entrainment occurs. The CFB has significant industrial

2014年11月21日 · gasoline and fluidized-bed reactors for making phthalic anhydride debuted in the 1940s. Today, about three-quarters of all polyolefins are made by a fluidized-bed process. The development of a specialized zeolite catalyst for cracking heavy oil into various fractions enabled the com-mercialization of the FCC circulating fluidized bed. In this

Fluidized bed is another type of incinerator where air is applied to sand to separate the sands and the plastics. An essential characteristic of a fluidized bed is the liquid-like behavior.

Fluidized beds are used extensively in the chemical process industries, particularly for the cracking of high-molecular-weight petroleum fractions. Such beds inherently possess excellent heat transfer and mixing characteristics.

A fluidized bed refers to a reactor design that uses fluidization, which is directly related to the supply of oxygen and the particles involved in the reaction. It is commonly used in industrial plants for processes such as coal gasification and catalytic reactions, offering high efficiency.
