<p>Micromixing characteristics of a tubular packed bed reactor with different packings were investigated by adopting the competitive parallel reaction, namely, the Villermaux–Dushman reaction. Better micromixing efficiency was achieved with the tube packed with Winpak® compared to that packed with Mini Ring or Mellapak™ or the empty tube. The segregation index (<i>X</i>_S) decreased as the volumetric flow rate increased, but increased with increasing volumetric flow ratio. Moreover, the micromixing time (<i>t</i>_m) was calculated using an incorporation model based on the experimental data. The minimum <i>t</i>_m value of the tube packed with Winpak® (<i>t</i>_m=1.54 ms) was less than that of the tube packed with Mini Ring (<i>t</i>_m=2.73 ms) or Mellapak™ (<i>t</i>_m=2.14 ms) or the empty tube (<i>t</i>_m=3.79 ms).</p>
