Various types of reactors are employed in continuous feed systems. The most common are the Continuous Stirred Tank Reactor (CSTR) and the Plug Flow Reactor (PFR). CSTRs are well-mixed reactors where reactants and catalysts are uniformly distributed. PFRs, on the other hand, allow reactants to flow through the reactor in a plug-like fashion, ensuring that they spend a consistent amount of time in the reactor.
