This paper presents new experimental results on the separation of an o-dichlorobenzene/p-dichlorobenzene mixture in a continuous moving crystal bed crystallization column under the top-fed operation mode. Local concentration distributions of the binary eutectic mixture were investigated as a function of the feed composition, reflux ratio, crystal bed height, and internal stirring speed. It is demonstrated that the key factor that is decisive to the separation capability of column crystallization is the reflux ratio. The experiments showed that product purities can easily exceed 99.0% over a wide range of feed compositions, 68-94 wt%, reflux ratios, 1.0-4.7, and crystal bed heights, 200-900 mm within a column of 50 cm i.d.

This paper introduces a novel structured metallic catalyst that improves mass transfer performance of a monolith reactor for highly exothermic gas–solid reactions. The monolith channels are designed to have metallic substrates that consist of two layers with one of the layers being the metallic support and another layer being a foam metal annular that is tightly deposited onto the support surface by some means. Parametrical studies based on a 2D monolith reactor model showed that the present design yields an enhanced mass transfer between the bulk fluid and the catalyst layer due to a decrease in external film resistance, and an enhanced mass transfer within the solid phase mainly due to the viscous flow effect within the porous catalyst layer.

Gas–liquid mass transfer from Taylor bubbles rising in 1, 2 and 3mm diameter capillaries of circular and square cross-sections was investigated for air–water system. The liquid-phase volumetric mass transfer coefficient kLa was obtained from experimental oxygen absorption dynamics. The experimental kLa values are in good agreement with the model developed by van Baten and Krishna (2004.Chemical Engineering Science 59, 2535–2545), with the additional assumption that the

利用动力学Monte Carlo(KMC)模拟方法计算了苯在Y沸石中扩散的自扩散系数，并考察了3种不同w-w位间跳跃扩散机制下的自扩散系数及其对温度和浓度的依赖关系。实验测量结果表明，苯在Y沸石中的长程运动主要是经SⅡ-W-SⅡ笼间的跳跃，基本不发生w-w之间的跳跃。相应得到的自扩散系数对温度的依赖关系较接近实验值；自扩散系数浓度依赖变化趋势为：先随覆盖量的增加而减小，到覆盖量大于 s位的饱和覆盖量 (每个超笼中4个分子)后，则随覆盖量增加先增后减，但也不会大于零覆盖量时扩散系数值，该情形与考虑 w-w之间跳跃时完全不同。此外，模拟结果表明，使用正确的跳跃机制是 KMC方法能正确模拟客体分子在沸石内扩散行为的关键。
