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 … WebJan 15, 2024 · As fixed-bed reactors are a central part of many methanation plant concepts, intensive research is being conducted into possible measures to improve reactor performance and safety. A central safety aspect in the operation of fixed-bed reactors is the avoidance of thermal runaway conditions, which occur if the released reaction heat …
