Reactor for catalytic reaction research

Abstract

The invention relates to a reactor for catalytic reaction research. It includes: kettle lid, kettle body, inlet, outlet, temperature measurement port, motor dirve shaft, blade and catalyst swivel. Kettle body is in a U shape. Inlet and temperature measurement port are on top of kettle lid. Outlet is at bottom of kettle body. Motor dirve shaft extrudes into kettle body through kettle lid. Blade is fixed on motor dirve shaft. Catalyst swivel is made up with upper clamping bar, lower clamping bar, inner screen cloth and outer screen cloth. It lies in bosom of kettle body. Inner screen cloth and outer screen cloth lies in middle of upper clamping bar and lower clamping bar which fixes with motor drive shaft. Upper clamping bar connects to blade. The invention can load plenty of catalyst to reduce evaluation period of catalyst. It can be used in reaction containing heavy components with a simple construction and long life.

Description

Technical field: [0001] The invention belongs to a reactor, and specifically relates to a reactor for catalytic reaction research. Background technique: [0002] When conducting research on heterogeneous catalysis in the laboratory, it is usually carried out in a fixed-bed reactor. The catalyst is loaded into the reactor, and the reactants enter from the upper part, flow out from the lower part, and pass through the catalyst bed. Under the action of the catalyst, the reactants are transformed into products. [0003] However, the fixed-bed reactor has the following disadvantages: (1) For catalysts with larger particles, due to the large gap between the reactor tube wall and the particles, a part of the reactants flow out along the tube wall without contacting the catalyst, thus failing to obtain real The result of the reaction. (2) In the study of reaction kinetics, it is necessary to investigate the relationship between reaction components, temperature and reaction rate. The reac...

[0003] However, the fixed bed reactor has the following disadvantages: (1) For catalysts with larger particles, due to the large gap between the reactor tube wall and the particles, a part of the reactants flow out along the tube wall without contacting the catalyst, so that the real catalyst cannot be obtained. The result of the reaction

[0008] (1) Since there are only two or four baskets, the loading capacity of the catalyst is limited, and only a small amount of catalyst can be loaded, which prolongs the selection cycle of the catalyst

[0009] (2) There are only two or four baskets, so the free space in the reactor is too large, and it is not easy to use in the reaction where the free space affects the reaction process

The heavy components that are easy to solidify will solidify in the casing, which will hinder the normal rotation of the stirring shaft, so it is not suitable for reactions containing heavy components in the product, such as Fischer-Tropsch synthesis reactions

[0014] (2) Since the motor and the transmission device are in the lower part of the reactor, if there is a problem with the motor and the transmission device, the reaction has to be stopped and the reactor is removed for processing, which will interrupt the long-term operation experiment for evaluating the life of the catalyst
