AXIAL MIXING AND SELECTIVITY - 2 CONSECUTIVE FIRST-ORDER REACTIONS

For reaction systems with linear kinetics, the performance of nonideal reactors can be accurately calculated by a simple numerical integration of the residence time dist bution. Experimental residence time distribution data were used to calculate reactor performance for a system of two consecutive first-order reactions. Mixing parameters for the dispersion and the CSTR cascade models were obtained from the variances of the residence time distributions. Model predictions gave excellent agreement with the integration results over a wide range of mixing intensity. Reactor selectivity was strongly dependent on mixing and reaction kinetics. © 1969, American Chemical Society. All rights reserved.
