WebA Plug-Flow Reactor (PFR) represents a steady-state channel with a cross-sectional area A A. Typically an ideal gas flows through it at a constant mass flow rate \dot {m} m˙. Perpendicular to the flow direction, the gas is considered to be completely homogeneous. In the axial direction z z, the states of the gas is allowed to change. In flow chemistry, a chemical reaction is run in a continuously flowing stream rather than in batch production. In other words, pumps move fluid into a reactor, and where tubes join one another, the fluids contact one another. If these fluids are reactive, a reaction takes place. Flow chemistry is a well-established technique for use at a large scale when manufacturing large quantities of a given material. However, the term has only been coined recently for its application on a laboratory scale …

WebA loop reactor is a hybrid type of catalytic reactor that physically resembles a tubular reactor, but operates like a CSTR. The reaction mixture is circulated in a loop of tube, surrounded by a jacket for cooling or heating, and there is a continuous flow of starting material in and product out. PFR (plug flow reactor) WebPfropfenströmung. Eine Pfropfenströmung (engl.: plug flow, auch Kolbenströmung) ist in der Strömungslehre eine Strömung in einem Rohr, bei der die Strömungsgeschwindigkeit fast überall im Strömungsquerschnitt gleich hoch ist.
