Abstract
Equations which predict the course of the reversible first order reaction A ⇄ R in backflow cell models of isothermal flow reactors are developed and compared to those of the continuous dispersion model. The conditions of convergence of the concentration A profile of the backflow cell model to that of the continuous dispersion model were investigated for isothermal first order irreversible (A ⇄ R) reactors of finite size. For this case figures are displayed which allow the models to be compared and the effects of axial mixing to be included in reactor design. The effect of backmixing upon the optimum temperature and maximum product yields of R is considered for the reversible reaction in the finite reactor.
