There are three basic types of fixed bed reactor: (1) axial adiabatic fixed bed reactor. The fluid flows through the bed along the axial direction, and there is no heat exchange between the bed and the outside world. (2) radial adiabatic fixed bed reactor. The fluid flows through the bed along the radial direction. Centrifugal flow or centripetal flow can be adopted. There is no heat exchange between the bed and the outside world. Compared with axial reactor, radial reactor has shorter flow distance, larger cross-sectional area and smaller fluid pressure drop. But the structure of radial reactor is more complicated than that of axial reactor. The above two forms are adiabatic reactors, suitable for the reaction heat effect is not large, or the reaction system can withstand adiabatic conditions caused by the reaction heat effect of the temperature changes. (3) The tubular fixed-bed reactor is composed of multiple reaction tubes in parallel. The catalyst is arranged in the tube or between the tubes, and the heat carrier flows through the tubes or tubes for heating or cooling. The diameter of the tubes is usually between 25 ~ 50mm, and the number of tubes can be as many as tens of thousands of roots. The tubular fixed bed reactor is suitable for the reaction with high thermal effect. In addition, there is a reactor composed of the above basic forms in series, called a multistage fixed bed reactor.
