Embodiment 1
[0024] Example 1. An example of a diversion tank-shaped catalyst structured packing assembly in a plate-type reactive distillation column
[0025] A diversion tank-shaped catalyst structured packing assembly in a plate-type reactive distillation tower, which is a component installed on the tray plate of the reaction section of the plate-type reactive distillation tower. It has a support frame composed of a 5mm diameter stainless steel rod, supporting The shape of the horizontal plane of the frame is that the two opposite sides are straight lines with a distance of 210 mm, and the other set of two opposite sides are arcs with a center distance of 300 mm, which matches the shape of the gas-liquid mass transfer area of the tray, such as image 3As shown, the supporting frame is high 120mm, wherein the height of the catalyst insert groove is 95mm (that is, adapting to the liquid level height of the tray during operation), and there are fixed legs 8 under the bottom surface of the...

[0027] Embodiment 2: Esterification produces butyl acetate
[0028] A reactive distillation column with an annual output of 100 tons of high-purity butyl acetate, with an inner diameter of 300mm and a tower height of 6.5m. The height of the upper rectifying section and the lower stripping section are both 2.0m, and they are filled with industrial conventional structured corrugated packing respectively. The height of the catalytic reaction section in the middle is 2.5m, with 10 sieve trays, the plate spacing is 250mm, the overflow weir is 35mm high, and the tray is equipped with diversion groove-shaped catalyst regular packing components. The filling unit of the catalyst insert adopts an elliptical cylinder with a major axis of 48mm and a minor axis of 16mm. The height of the insert is 110mm, and the height from the bottom to the tray is 20mm; the width of the card slot is 18mm, and the average flow channel width is 26mm. The catalyst adopts strong acid ion resin with an avera...
