Description

Technical Field

[0001] The utility model relates to the technical field of laboratory experimental devices, and particularly relates to an efficient gas-liquid distribution sheet. Background Art

[0002] In physicochemical experiments using catalysts, it is necessary to maintain the contact between the reactants and the catalyst. The larger the contact area between them, the faster the reaction. The traditional operation of such experiments is to crush the catalyst and stir during the reaction process to increase the contact area between the reactants and the catalyst. However, this operation requires continuous stirring and is not applicable to all reaction experiments. Moreover, there is a minimum limit for the crushing particle size of the catalyst. Therefore, there is now an operation method of using a dispersion sheet to disperse the experimental substances to increase the contact area between the reactants and the catalyst. The dispersion sheet is a disk-shaped object with dense pores. It increases the dispersion of the reactants through the holes on it, thereby increasing the contact area between the substances and the catalyst. However, this dispersion sheet has the problem of difficult manufacturing, and the regular and uniform hole shapes result in general dispersion effects. Therefore, it is necessary to develop a dispersion sheet with a new structure. Content of the Utility Model
