Abstract

This work describes a method of determining axial dispersion coefficients in a packed bed chemical reactor. This is done by measurement of the fractional conversion of acetic anhydride to acetic acid, by first order reaction in dilute solution. The reaction is carried out at various flow rates in a four inch diameter reactor packed with one-half inch Raschig rings. analysis is by the aniline-rater method. Calculation of the dispersion coefficients is by trial using a digital computer. The results are presented graphically and compared to results obtained by other methods. The results of this study are found to correspond to those of other investigations. The advantages of the steed stale determination over methods involving pulse tracer material are discussed.
