The principle of structured catalytic packing involves loading catalysts onto a material structure with excellent mass transfer properties. During distillation operation, rising vapor and descending liquid come into countercurrent contact on the packing surface, simultaneously facilitating mass transfer and chemical reactions. The products generated through reaction (particularly low-boiling-point substances) are promptly distilled out, breaking the equilibrium constraints and driving the reaction toward a positive direction. This achieves synchronized and synergistic enhancement of both "reaction" and "separation" within a single device.
