Transient behaviour of a non-ideal tubular reactor

Experimental data are reported for the unsteady state behaviour of a laminar flow reactor with first order homogeneous liquid phase reaction. The data are in agreement with the predictions of the dispersion model, using previously reported reaction-dependent dispersion coefficients which directly gives the bulk mean concentration. The use of proper boundary conditions, ignored in a recent paper on this topic⁽¹⁹⁾, is found to significantly influence the predictions. Unlike the conclusion drawn in⁽¹⁹⁾ it is shown that the Taylor model is unable to correctly predict the reactor length for fast reactions even for high conversions.
