Study on catalytic distillation processes. Part IV: axial dispersion of liquid in catalyst bed of catalytic distillation column

摘要

The backmixing characteristics of the liquid in a countercurrent two-phase flow catalytic distillation column was examined. The residence time distribution (RTD) curves were interpreted using the axial dispersion model. The axial Peclet number was obtained by the least-squares fitting method in the entire time domain, and the correlation, Pe_a = 10.487 Re_L~(-0.224)Re_(G-0.0765), was obtained. An example is given to show the effect of axial dispersion on the yield of Methyl Tert-Butyl Ether (MTBE) synthesized using catalytic distillation.
