The Kinetic Reactor Unit Operation in CHEMCAD has a plug flow mode for liquid, vapor only or mixed phases and allows reactor volume or conversion to be specified.

For dynamic simulation you can specify the hold up.

The Stoichiometric, Gibbs and Equilibrium Reactor Unit Operations do not have a plug flow option. The hydraulics within a tubular reactor could be studied using the Pipe Unit Operation Dynamic batch reactor allows you to specify the physical dimensions, reaction kinetics and heat transfer film coefficients.
