Tubular reactors are used most often for gas-phase reactions. A schematic and a photograph of industrial tubular reactors are shown in Figure 1-8. In the tubular reactor, the reactants are continually consumed as they flow down the length of the reactor. . For a fluid-solid heterogeneous system, the rate of reaction of a species A is defined as
A tubular reactor is a fundamentally simple continuous reactor where there are no moving parts other than pumps that deliver the reactants. In a typical slow chemical reaction system where long residence times are required, the fluids passing through a tubular reactor are in the laminar flow regime even when the materials are low viscosity .

An advantage of batch over continuous stirred–tank and tubular reactors is that a single experiment with samples taken at frequent intervals in effect scans the entire conversion range. A disadvantage is that samples must be taken from the reactor itself. For elucidation of mechanisms, rate data at very low conversions may be highly desirable.
