Document Type and Number:
WIPO Patent Application WO/2023/045421
Kind Code:
A1
Abstract:
The present application relates to the technical field of absorption tower fillers, and provides a preparation method for an absorption tower filler, and a filler. The preparation method comprises: setting parameters of a 3D printing device; planning a printing path according to the model slice of a filler; and sequentially printing the matrixes of the filler according to the path, wherein a special-shaped structure is formed on at least one layer of matrix of the filler and is suitable for increasing the specific surface area and the porosity of the filler. According to the preparation method for the absorption tower filler provided by the present application, the 3D printing device is used for preparing the filler, the filler that is difficult to produce or even cannot be produced by means of a traditional production process and is complex in shape can be produced, no mold is needed, thermal treatment or other processes are not needed, the preparation speed is fast, and the improvement of the production efficiency is facilitated. Moreover, the special-shaped structure printed on the matrix can increase the specific surface area and the porosity of the filler, so that the gas-liquid contact can be more sufficient, and the improvement of the reaction efficiency is facilitated.
