| Abstract: | The liquid-solid mass transfer coefficients and liquid flow-ratewithin the catalyst capsule have been measured in a countercurrent flow column by this study. The measurements were completed under the temperature 25℃ and the normal pressure in a glass column with the diameter 56mm and the catalyst-bed-height 528mm. The correlations for calculation of the liquid-solid mass transfer coefficients and liquid flow-rate within the catalyst capsule were obtained by regressing the experimental data, which can be applied to simulate the catalytic distillation process for the hydrolysis of the methyl acetate. |
