Description

Technical Field

[0001] The present application relates to the technical field of catalyst evaluation and screening, and in particular to an anti-clogging catalyst screening device based on solid-phase catalysis. Background Art

[0002] Catalysts play a vital role in the modern chemical industry. They can significantly accelerate the rate of chemical reactions, improve the selectivity of reactions, and reduce the energy required for reactions to a certain extent. In order to evaluate a variety of catalysts and screen their activity, catalyst screening equipment is used.

[0003] Catalyst screening and evaluation equipment is an important tool for studying and testing the performance of various catalysts, including various reactor types such as fixed bed reactors. However, in the actual evaluation and screening process of catalysts, especially when using fixed bed reactors, the problem of reactor blockage is often encountered, which becomes an important factor restricting the accuracy of catalyst performance testing and affecting the reliability of evaluation results.

[0004] The fixed bed reactor is filled with catalyst particles, and the reactants are reacted by passing through the catalyst continuously or intermittently in the bed. In this process, the reasons for the blockage of the catalyst bed are diverse and complex, mainly including the following aspects:

[0005] 1. Catalyst particle breakage and accumulation: During catalyst loading, reaction process or unloading, catalyst particles may be broken by mechanical stress to form fine particles. These particles tend to aggregate inside the bed, thereby blocking the pores between catalysts and affecting the normal passage of materials.

[0006] 2. Carbon deposits or sediment formation: In certain catalytic reactions, especially those involving high-temperature reactions such as cracking of organic matter and dehydrogenation, carbon deposits or inorganic sediments are easily formed on the surface or in the pores of the catalyst. Over time, the accumulated substances can cause the pores of the catalyst bed to narrow or even become blocked.

[0007] 3. Insufficient purity of reactants: The raw materials contain dust, impurities or other solid particles that are not easy to participate in the reaction. These substances may be retained in the catalyst bed during the reaction and cause blockage.

[0008] 4. Improper operating conditions: For example, excessively high temperature may cause the catalyst to deform or melt, or the flow rate may be too low, causing the material to stay in the bed for too long, increasing the probability of carbon deposits and sediment formation.

[0049] Example

In order to store the screening device, a rack 140 is mounted on the outer surface of the reactor component 100. The rack 140 is used to store and install the reactor component 100, the gas distribution component 110, the gas analysis component 120, the central processing unit 130, the rack 140 and the anti-clogging structure;

[0051] The rack 140 is divided into a plurality of cavities, the middle and right cavities are used to assemble the catalyst evaluation and screening equipment, and the left cavity can be used to assemble the anti-blocking and cleaning structure of the reaction storage unit 400;

[0052] Catalyst screening refers to the process of using multiple catalysts to react with the same target, comparing their catalytic effects, and evaluating the activity of the catalysts to achieve different types of catalyst screening;

[0053] When the reactor component 100, the gas distribution component 110, the gas analysis component 120 and the central processor 130 are used to perform a plurality of catalyst activity screenings, the specific experimental steps for examining and screening the catalyst activity are as follows:

[0054] 1. Catalyst loading: Weigh the required mass of catalyst and put it into the reactor component 100, insert a small amount of high-temperature cotton at both ends of the catalyst to fix the catalyst bed, and place the loaded tubular reactor in a heating furnace;

[0055] 2. Check the tightness of the pipeline: First, introduce N2 to check the airtightness of the reaction device. Open the valve of the N2 cylinder, set the gas flow rate flowing into the device on the mass flow meter, and seal the outlet. When the introduced gas makes the pressure gauge reading reach 0.1MPa, stop ventilation. If the pressure does not drop within 10 minutes, it means that the reaction device is well sealed.

[0056] 3. Gas distribution: Set the given value of each mass flow meter and distribute the gas (use N2 as carrier gas to simulate the flue gas flow required for the experiment). When the gas is evenly mixed and reaches stability for a period of time, the chemical agent adsorbs NO to saturation, which can avoid the reduction of NO caused by the adsorption of the chemical agent;

[0057] 4. Heating reaction: Set the temperature of the heating furnace through program heating, and heat it up. After reaching the reaction temperature, each temperature is stabilized for more than 1 hour before analysis;

[0058] 5. Analysis of NO removal rate: Samples were taken at the air inlet and outlet respectively. After the gas was collected in a 2L aluminum sampling bag, the inlet and outlet NO concentrations were measured using a KM900 handheld flue gas analyzer to analyze the reaction activity of the catalyst for catalytic reduction of NO under different experimental conditions.

[0059] 6. Calculation of NO conversion rate: Based on the NO concentration values ​​before and after the reaction, the NO conversion rate at each reaction temperature is calculated and defined as the denitrification rate. This data is used as an indicator to measure the catalyst activity.

[0060] Denitrification rate = inlet NO concentration - outlet NO concentration / inlet NO concentration;

[0072] The anti-blocking component 700 includes an air pump 710 for providing power. The output end of the air pump 710 is connected to a main distribution pipe body 711 for delivering the gas generated by the air pump 710. The anti-blocking component 700 also includes a fixed gas cylinder 720 and a lower gas cylinder 730. The fixed gas cylinder 720 and the lower gas cylinder 730 are symmetrically arranged with the clamping seat 610 as a base point, and the distance between the opposite sides of the fixed gas cylinder 720 and the lower gas cylinder 730 is greater than the length of the reaction storage member 400. In this way, when the reaction storage member 400 is inserted into the clamping seat 610, its upper end contacts the bottom of the fixed gas cylinder 720, and the lower end of the reaction storage member 400 contacts the bottom of the lower gas cylinder 730, so as to facilitate subsequent gas delivery.

Then, the reaction storage part 400 is adjusted to a vertical state, and the fixed air cylinder 720 and the lower air cylinder 730 are used for intermittent ventilation, so as to blow the cleaning balls in the reaction storage part 400 to float, and clean the impurities attached to the inner wall of the reaction storage part 400, so as to avoid blockage of the reaction storage part 400 due to long-term use.

[0079] Specifically, the working principle of the anti-blocking catalyst screening equipment based on solid-phase catalysis is:

[0080] When cleaning the reaction storage parts 400, the driving motor 1 320 can drive the turntable 310 to rotate, change the positions of different reaction storage parts 400, and use the mechanical arm 510 and the gripper 520 to send the reaction storage parts 400 into the clamping seat 610. The clamping seat 610 cooperates with the driving motor 2 600 to fix the reaction storage parts 400 therein and adjust the angles of the reaction storage parts 400.

[0081] When the reaction storage part 400 is in a vertical state, the air pump 710 starts to work and quantitatively delivers gas to the fixed gas cylinder 720. Since the fixed gas cylinder 720, the reaction storage part 400 and the lower gas cylinder 730 are in a vertical state and are interconnected, the gas delivered by the fixed gas cylinder 720 flows through the reaction storage part 400 and is finally discharged through the lower gas cylinder 730. The lower gas cylinder 730 can detect the flow rate of the inflowing gas to determine the amount of gas introduced into the reaction storage part 400 at one end of the time and determine whether there is a blockage inside the reaction storage part 400. If there is a blockage, the following treatment is performed;

[0082] When the blockage is light, the valve body 740 is used to control the opening and closing of the lower gas cylinder 730, and then the gas is mixed into the fixed gas cylinder 720 and the lower gas cylinder 730 at intervals to flush the interior of the reaction storage unit 400 with gas;

[0083] When the blockage is serious, the reaction storage unit 400 is adjusted to a horizontal state, with its two ends in contact with the ends opposite to the collecting tube 810 and the air head 820. The collecting tube 810 is ventilated to blow the cleaning balls stored inside it into the reaction storage unit 400, and then the reaction storage unit 400 is adjusted to a vertical state, and the fixed air cylinder 720 and the lower air cylinder 730 are used for intermittent ventilation to blow the cleaning balls in the reaction storage unit 400 to float and collide, thereby cleaning the impurities attached to the inner wall of the reaction storage unit 400 to avoid blockage of the reaction storage unit 400 due to long-term use. In this way, a reasonable clearing method is used to prevent blockage of the reaction storage unit 400 at different degrees of blockage; thereby reducing manual operation steps and conveniently preventing blockage of multiple reaction storage units 400.

[0084] The electronic components and models used in the present invention can be determined according to actual needs.
