催化精馏塔中催化剂填料传质特性研究Ⅰ-气液传质系数的测定

Mass Transfer Characteristics in Catalyst Packing Bed for the Catalytic Distillation ProcessPart I: The Measurement of the Mass Transfer Coefficients for Gas-Liquid

通过气液在塔内的逆向流动， 测定了气液传质系数－ 实验在常压、２５ ℃下进行， 采用内径为５３ ｍ ｍ 的玻璃管， 玻璃管中的催化剂捆束总高度为５２８ ｍ ｍ－ 对实验数据进行回归处理， 得到了传质系数的关联式，

The mass transfer coefficients for gas-liquid 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 53 mm and the catalyst-bed-height 528 mm The correlations for calculation of the mass transfer coefficients were obtained by regressing the experimental data, which can be employed to simulate the catalytic distillation process for the hydrolysis of the methyl acetate
