  7. CSTR

  8. Tubular Reactor (Plug Flow Reactor) (PFR) • In addition to the CSTR and batch reactors, another type of reactor commonly used in industry is the tubular reactor. It consists of a cylindrical pipe and is normally operated at steady state. • In the tubular reactor, the reactants are continually consumed as they flow down the length of the reactor. • In modeling the tubular reactor. We assume that the concentration varies continuously in the axial direction through the reactor.

  12. Plug Flow Reactor Mole Balance PFR: The integral form is: This is the volume necessary to reduce the entering molar flow rate (mol/s) from FA0 to the exit molar flow rate of FA.

  13. Packed Bed Reactor PBR The integral form to find the catalyst weight is:
