A device for precise control of catalytic reaction and its application method

Abstract

The invention discloses a device for precisely controlling the catalytic reaction, which is used to control the contact area between the catalytic fiber bundle and the reactant. The catalytic fiber bundle includes several catalytic fibers, the catalytic fiber is a skin-core structure, and the core layer is made of catalytic material Made, the first air bag wraps around the catalytic fiber bundle and controls its movement to the reactant along the guide rail to control its contact with the reactant; the second air bag wraps and controls the catalytic fiber bundle along the circumferential direction of the catalytic fiber bundle Tight bundle or slack, when the catalytic fiber bundle is tight, the cutter cuts along the radial direction of the catalytic fiber bundle. The invention uses the skin-core structure catalytic fiber, the catalytic material is in the core layer and covered by the skin layer, the contact area between the catalyst and the reactant is defined, and the end surface is cut and updated to eliminate the coverage by the reactant or its reaction product or other substances The end face, so as to realize the catalytic reaction again, so as to precisely control the reaction degree of the catalytic reaction.

Description

technical field [0001] The invention relates to the technical field of catalytic reaction control, in particular to a device for precisely controlling catalytic reactions and a method for using the same. Background technique [0002] A catalytic reaction refers to a chemical reaction that takes place under the action of a catalyst. In a chemical reaction, some of the original chemical bonds of the reacting molecules must be broken and form new chemical bonds, which requires a certain amount of activation energy. In some systems where chemical reactions are difficult to occur, the addition of a third substance (catalyst) that helps to rearrange the chemical bonds of the reacting molecules can reduce the activation energy of the reaction, thereby accelerating the chemical reaction and controlling the selectivity and quality of the product. Stereo regularity. [0003] The process of catalytic reaction is that the reactants react around the catalyst, while the peripheral react...

Problems solved by technology

[0004] The control of the catalytic reaction includes the control of the contact area between the catalyst and the reactant. The current conventional practice is to control the contact area of ​​the two by controlling the dosage form and dosage of the catalyst, but this method is difficult to control the contact area between the two in actual operation. Precise control of the area, especially the widely used granular catalysts, although catalysts with different particle sizes have theoretical surface areas, but due to manufacturing errors, inter-particle abrasion or aggregation during transportation and storage, the actual use It is difficult to accurately confirm the contact area with the reactant
