Description

Technical Field

[0001] This invention belongs to the field of Fischer-Tropsch catalyst reduction reaction technology, and particularly relates to a Fischer-Tropsch catalyst reduction reactor. Background Technology

[0002] The Fischer-Tropsch catalyst reduction reaction refers to the process of reducing the oxides in the Fischer-Tropsch catalyst to a metallic state under specific conditions using a reducing agent. The specific steps generally include desulfurization of the feed gas, preparation of the catalyst slurry, and the reduction reaction.

[0003] A Fischer-Tropsch catalyst reduction reactor is disclosed in publication number CN204710288U. The reduction reactor includes a cylindrical reduction section, a reduced diameter section integrally connected to the upper end of the reduction section and coaxial with the reduction section, and a dust separation section integrally formed by a transition section and an expanded diameter section with a diameter larger than that of the reduction section. The lower end of the transition section is sealed to the lower outer surface of the reduced diameter section, so that the reduced diameter section is located in the cavity of the dust separation section.

[0004] Existing Fischer-Tropsch catalyst reduction reactors still have the following shortcomings:

[0005] 1. In the Fischer-Tropsch catalyst reduction reaction, the feed gas must be desulfurized first. This is to reduce the sulfur content and avoid affecting the reaction, and also to use the feed gas as an active gas.

[0006] 2. The catalyst slurry is prepared by mixing Fischer-Tropsch catalyst with liquid paraffin. During the reaction, the catalyst slurry should be discharged into the reactor. However, due to the strong adhesive properties of paraffin, direct discharge of the catalyst slurry will result in a large amount of catalyst slurry adhering to the inner wall of the reactor, which is not conducive to subsequent cleaning. Utility Model Content

[0007] The purpose of this invention is to solve the problem in the existing technology where the raw gas is desulfurized first, and because paraffin has strong adhesion, it is directly discharged into the catalyst slurry, which leads to a large amount of catalyst slurry adhering to the inner wall of the reactor, which is not conducive to subsequent cleaning. Therefore, a Fischer-Tropsch catalyst reduction reactor is proposed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A Fischer-Tropsch catalyst reduction reactor includes: a support frame, the support frame including a support base plate, a fixed frame fixedly connected to the side of the support base plate, a fixed rod fixedly connected to the upper surface of the fixed frame, a sliding groove provided on the side of the fixed frame, a displacement plate slidably connected in the sliding groove, a desulfurization structure provided beside the support frame, and a reaction structure provided above the displacement plate.

[0010] Preferably, the reaction structure includes a flask, an exhaust pipe is fixedly connected to the side of the flask, a rubber stopper is snapped into the upper opening of the flask, and a spherical tube is provided above the flask.

[0011] Preferably, an internal tube is fixedly connected to the lower part of the spherical tube, the internal tube passes through the rubber stopper and extends into the flask, and a side tube is fixedly connected to the side of the spherical tube.

[0012] Preferably, the fixing rod is connected to a clamping member through and engaged with the flask, and the open end of the clamping member is held on the outer side of the upper end of the flask.

[0013] Preferably, the desulfurization structure includes an air pump, the output end of which is fixedly connected to the lower end of the filter box via an air pipe, the upper end of the filter box is fixedly connected to a connecting pipe, and the end of the connecting pipe is fixedly connected to the upper end of the spherical tube.

[0014] Preferably, the filter box contains three different filter layers, which are respectively set as activated carbon, molecular sieve and silica gel.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model, by setting a desulfurization structure, can input raw gas into the gas pump, and the gas pump will input the raw gas into the filter box through the gas pipe. The filter box is equipped with activated carbon, molecular sieve and silica gel. Because the filter layer material has tiny pores inside, it can effectively absorb sulfur in the raw gas. The desulfurized raw gas will be input into the spherical tube and the flask through the connecting pipe.

[0017] 2. This utility model has a unique reaction structure. An alcohol lamp can be placed between the supporting base plate and the displacement plate to heat the flask. The built-in tube fixed at the bottom of the spherical tube extends into the flask. The catalyst slurry can be discharged into the spherical tube through the side tube and then discharged into the flask, avoiding contamination of the inner wall of the flask.
