WebFluidized bed chemical vapor deposition (FBCVD) is one of the most efficient techniques to functionalize, to deposit on, or to coat each individual particle of a powder from gaseous … 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 … See more The solid substrate material (the catalytic material upon which chemical species react) in the fluidized bed reactor is typically supported by a porous plate, known as a distributor. The fluid is then forced through the … See more Fluidized bed reactors are a relatively new tool in the chemical engineering field.
