Fixed-Bed Reactors - Uni Stuttgart

Catalytic fixed-bed reactors are the most im­ portant type of reactor for the synthesis of large­ scale basic chemicals and intermediates. In these reactors, the reaction takes place in the form of a heterogeneously catalyzed gas reaction on the surface of catalysts that are arranged as a so­ called fixed bed in the reactor.

Continuous flow reactors

The properties of the continuously operated fluidised bed reactor lie, generally, somewhere between these extremes. An ordered series of CSTRs or FBRs may approximate, in use where the outlet of one reactor forms the inlet to the next reactor, to an equivalent PBR. The transport of momentum, heat and mass in these continuous reactors .

Chemical Reactors: Semi-Batch Reactors

A semi-continuous reactor is a reactor for a multiphase reaction in which one phase flows continuously through a vessel containing a batch of another phase. The operation is thus unsteady-state with respect to the batch phase, and may be steady-state or unsteady-state with respect to the flowing phase, as in a fixed-bed catalytic reactor or a fixed bed gas-solid reactor .
