Device for accurately controlling catalytic reaction and using method thereof

Abstract

The invention discloses a device for accurately controlling a catalytic reaction. The device is used for controlling the contact area of a catalytic fiber bundle and a reactant, the catalytic fiber bundle comprises a plurality of catalytic fibers, each catalytic fiber is of a skin-core structure, a core layer of each catalytic fiber is made of a catalytic material, and a first air bag wraps the catalytic fiber bundle in the circumferential direction, controls the catalytic fiber bundle to move towards the reactant along a guide rail and is used for controlling the catalytic fiber bundle to make contact with the reactant, a second air bag wraps the catalytic fiber bundle in the circumferential direction of the catalytic fiber bundle and controls the catalytic fiber bundle to be tightened orloosened, and when the catalytic fiber bundle is tightened, a cutter cuts in the radial direction of the catalytic fiber bundle. The fiber is catalyzed through the skin-core structure, the catalyticmaterial is located in the core layer and coated with the skin layer, the contact area of the catalyst and reactants is defined, and the end faces covered by the reactants or reaction products thereofor other substances are eliminated by cutting and updating the end faces, so that the catalytic reaction occurs again, and the reaction degree of the catalytic reaction is accurately controlled.

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
