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 … WebMultitubular Fixed Bed Reactor. A fixed bed reactor is heterogeneous reaction system. In chemical industries, we can find this type of installations for gas phase catalytic reactions most frequently. As we can …
