Tubular reactors resemble batch reactors in providing initially high driving forces, which diminish as the reactions progress down the tubes. Flow in tubular reactors can be laminar, as with viscous fluids in small-diameter tubes, and greatly deviate from ideal plug-flow behavior, or turbulent, as with gases.

A Plug Flow Reactor (PFR) consists in a long, straight pipe in which the reactive fluid transits at steady-state (no accumulation). The main assumptions of this model are that the fluid is completely mixed in any cross-section at any point, but it experiences no axial mixing, i.e. contiguous cross-sections cannot exchange mass with each other.
