A gas-liquid dual-purpose catalytic reaction device

Abstract

The invention discloses a gas-liquid dual-purpose catalytic reaction device comprising a reaction cavity, a catalyst fixation device, a heating mechanism, a motor and a piston, wherein the reaction cavity is used for injecting reactants; the catalyst fixation device is arranged in the reaction cavity and is a hollow columnar body, the interior of a side wall of the columnar body is processed into a hornet-shaped structure for holding a catalyst and preventing the catalyst from moving out, and meanwhile the columnar body serves as a flow passage of the reactants; a small end of the piston is connected with an output shaft of the motor, and a large end of the piston is located in the hollow cavity of the catalyst fixation device; and the heating mechanism is arranged between the side wall of the reaction cavity and the side wall of the catalyst fixation device. According to the gas-liquid dual-purpose catalytic reaction device disclosed by the invention, full contact of the catalyst and the reactants is realized by the change of the pressure, and thus the reaction rate and the use efficiency of the catalyst are improved.

Description

technical field [0001] The invention belongs to the field of catalytic reaction, and more specifically relates to a gas-liquid dual-purpose catalytic reaction device and method. Background technique [0002] With the rapid development of the industrial field, the role of catalysts that can improve reaction efficiency and reaction quality is becoming more and more important. Catalytic gasification of sewage, catalytic reforming of gas, catalyst denitrification, etc. are widely used in industry, and they are related to energy. The effective use of it also plays a vital role in environmental protection. [0003] However, the use of the catalyst will bring many problems, such as the wear and tear of the catalyst, the failure of the catalyst to be recovered, and more importantly, if the catalyst cannot fully contact the reactant, the reaction efficiency will be greatly reduced.

AI Technical Summary

Problems solved by technology

[0003] However, the catalyst will bring many problems in the process of use, such as the wear and tear of the catalyst, the failure of the catalyst to be recovered, and more importantly, if the catalyst cannot fully contact with the reactants, the reaction efficiency will be greatly reduced.

Especially for gas or liquid reactants, the use of catalysts cannot improve the effective contact between catalysts and reactants. At the same time, in some reaction processes, the reaction products are easy to carry catalysts and discharge, resulting in loss of catalysts.

[0004] At present, in the catalytic process of gas or liquid, many reactions rely on the passive contact between gas or liquid and the catalyst, especially in the aspect of experimental equipment, which not only wastes a lot of time, but also obtains unsatisfactory results.
