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. This process, known as fluidization, imparts many important advantages … WebApr 29, 2024 · Fixed bed reactors like ours are closing that gap, because we are beginning to take the same process that has been developed in the research laboratory for the standard 2D surface and transfer it into manufacturing scale production systems.
