Description

Technical Field

[0001] This invention relates to the field of catalyst activation technology, specifically to a hydrogenation catalyst activation device and activation method. Background Technology

[0002] Industrially used hydrogenation catalysts typically use refractory oxides such as alumina, silica, and molecular sieves as supports, and one or more of Group VIB metals (such as molybdenum and tungsten) and Group VIII metals (such as cobalt and nickel) as active metal components. These active metal components are dispersed on the support in an oxidized state. However, during the hydrogenation reaction, the active metal components of the catalyst have higher activity and stability when they are in a sulfide state (the metal exists in the form of sulfides: Co9S8, MoS2, Ni3S2, WS2, etc.). Therefore, the catalyst needs to be pre-sulfided before use to convert the active metal from the oxidized state to the sulfide state. These hydrogenation catalysts mainly include hydrorefining catalysts, hydrocracking catalysts, and hydromodification catalysts.

[0003] Existing activation technology involves directly spraying the prepared activation solution onto the catalyst, stirring it evenly, and then carrying out the activation reaction. This method cannot guarantee that the activation solution will spread out and carry out a uniform activation reaction during the reaction, resulting in a low reaction rate. In addition, the vulcanization time of the vulcanizing agent during the reaction process is relatively long, making it difficult to control the activation process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hydrogenation catalyst activation device and activation method, which solves the problems of uneven dispersion of the activation liquid during the reaction, low reaction rate, and difficulty in controlling the process due to excessively high temperature during the reaction.

[0005] This invention provides a hydrogenation catalyst activation device, including a reaction vessel;

[0007] A driving mechanism is used to drive the mounting bracket to rotate around the horizontal central axis of the mounting bracket, and at the same time drive the reactor to rotate around the vertical central axis of the reactor;

[0008] A uniform material distribution mechanism is provided inside the reactor. The top of the reactor is also provided with an activation liquid spraying device. The uniform material distribution mechanism is located below the activation liquid spraying device and is used to receive the activation liquid and uniformly disperse the activation liquid on the catalyst.

[0009] Preferably, the device also includes a base, with a vertical plate fixedly connected to one side of the base. The driving mechanism includes a rotating shaft, a drive motor, a driving bevel gear, and a driven bevel gear. The mounting frame is a U-shaped mounting frame, and the reactor is installed in the open end of the U-shaped mounting frame. The middle of the vertical section of the mounting frame corresponding to the open end is fixedly connected to one end of the rotating shaft. The other end of the rotating shaft passes through the vertical plate and is connected to the drive motor. The driving bevel gear is fixed on the vertical plate, and the rotating shaft passes through the center of the driving bevel gear and is connected to the mounting frame. The vertical section of the mounting frame is also provided with a through groove, and the driven bevel gear is located in the through groove and meshes with the driving bevel gear. The top of the driven bevel gear is also connected to a transmission shaft. The transmission shaft passes through to the top of the mounting frame and is fixedly connected to a first driving pulley. The top of the reactor is fixedly connected to the first driven pulley via a connecting rod. The first driven pulley and the first driving pulley are driven by a first transmission belt.

[0010] Preferably, the material leveling mechanism includes a composite cone frame, which is composed of two cone-shaped frames that interlock from top to bottom. A heat-conducting frame is also fixedly connected to the middle of the composite cone frame. A plurality of material leveling holes are uniformly provided on the surfaces of the composite cone frame and the heat-conducting frame. An electric heater is installed on one side of the middle of the heat-conducting frame. The composite cone frame is sealed to the inner wall of the reactor.

[0011] Preferably, the drive motor is mounted on the base, the drive end of the drive motor passes through the upright plate and is fixedly connected to a second drive pulley, and a second driven pulley is mounted on the end of the rotating shaft. The second drive pulley and the second driven pulley are driven by a second transmission belt.

[0012] Preferably, the side wall of the reactor is provided with an activation liquid inlet pipe, an inert gas inlet pipe, an inert gas outlet pipe, and an activation liquid outlet pipe in sequence from top to bottom. A linear motion module is also installed on the base. An operation box is movably installed on the top of the linear motion module. An activation liquid inlet connector, an inert gas inlet connector, an inert gas outlet connector, and an activation liquid outlet connector are provided with an activation liquid inlet connector, an inert gas outlet connector, and an activation liquid outlet connector in sequence from top to bottom on the operation box. A pressure stabilizing valve is installed on one side of the bottom of the reactor. The linear motion module is used to move the operation box closer to or away from the reactor, thereby completing the docking and separation of the pipes.

[0013] Preferably, an electric valve is installed on the outer diameter of the activation liquid inlet pipe, the inert gas inlet pipe, the inert gas outlet pipe, and the activation liquid outlet pipe. The ends of the activation liquid inlet connector, the inert gas inlet connector, the inert gas outlet connector, and the activation liquid outlet connector are all provided with conical sealing plugs, which can seal and connect with the activation liquid inlet pipe, the inert gas inlet pipe, the inert gas outlet pipe, and the activation liquid outlet pipe.

[0014] Preferably, the activation liquid spraying device includes a water ring and a plurality of atomizing nozzles evenly installed at the bottom of the water ring, and the outlet end of the activation liquid inlet pipe extends into the water ring.

[0015] Preferably, a rotating disk is installed at both the upper and lower ends of the reactor, and the two rotating disks are movably connected to the mounting frame via connecting rods.

[0016] The present invention also provides an activation method using the above-described hydrogenation catalyst activation apparatus, comprising the following steps:

[0017] An activating liquid and an inert gas are introduced into a reactor containing a catalyst.

[0018] The electric heater controls the heat-conducting frame to start heating up, and the activation liquid is sprayed onto the material distribution mechanism;

[0019] The drive motor drives the rotating shaft to rotate, thereby causing the mounting frame to rotate. As the mounting frame rotates, it drives the first drive pulley to rotate through the action of the drive bevel gear and the driven bevel gear. Through the transmission of the first transmission belt and the first driven pulley, the reactor rotates and the activation reaction begins.

[0020] After the reaction is complete, collect the solution.

[0021] Preferably, the activation solution contains a porous support composition, which is composed of a porous support, a sulfurized oil, an organic solvent, and additives. The inert gas includes one or more of nitrogen, argon, helium, carbon dioxide, and water vapor. The inlet temperature of the reactor is controlled at 130-160°C, and the volume hourly space velocity is 0.2-20 h⁻¹. -1 The final temperature of the reactor is 180-280℃, and the reaction time is 5-8 hours.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention adopts a rotary reactor, which is driven by two sets of belts during the reaction, so that the reactor and the mounting frame can rotate around the horizontal central axis of the mounting frame. At the same time, the reactor can also rotate on its own axis. In addition, a uniform material distribution mechanism is set in the middle of the reactor, so that the activation liquid can always be evenly distributed in the reactor, which greatly improves the reaction rate.

[0023] This invention adds a porous support composition to the activation solution, uses an electric heater to appropriately control the reaction temperature, and introduces the porous support by impregnation with auxiliaries, organic solvents and other additives to share some of the heat. This allows the hydrogenation catalyst to disperse and release heat during the activation process, avoiding excessively high local temperatures in the hydrogenation catalyst bed and thus preventing the catalyst performance from being affected.

[0045] The present invention also provides an activation method using the above-described hydrogenation catalyst activation apparatus, comprising the following steps:

[0046] An activation liquid and an inert gas are introduced into the catalyst-filled reactor 15; the catalyst can be moved in and out of the reactor 15 by opening the rotating disk 16 at the bottom of the reactor 15.

[0047] The electric heater 3504 controls the heat conduction frame 3503 to start heating, and the activation liquid is sprayed onto the uniform material mechanism 35.

[0048] The drive motor 4 drives the rotating shaft 3 to rotate, thereby causing the mounting frame 9 to rotate.

[0051] like Figure 1-8 As shown, this embodiment provides a hydrogenation catalyst activation device, including a base 1. A vertical plate 2 is fixedly connected to the top left of the base 1 for connection and fixation. A rotating shaft 3 is connected to the inner top of the vertical plate 2 via a movable bearing for convenient motion transmission. The right end of the rotating shaft 3 is fixedly connected to the middle of the left end of the mounting frame 9. A reaction vessel 15 is located in the middle of the mounting frame 9, which is the main reaction area. From top to bottom, the middle of the right end of the reaction vessel 15 is provided with an activation liquid inlet pipe 17, an inert gas inlet pipe 18, an inert gas outlet pipe 19, and an activation liquid outlet pipe 20 for convenient introduction of raw materials. A linear motion module 22 is installed on the top right of the base 1 for controlling the movement of the operation box 23. This embodiment uses rodless cylinder control, but a motor combined with a ball screw structure can also be used. The top of the linear motion module 22 is movably equipped with an operation box 23. The left middle of the operation box 23 is provided with an activation liquid inlet connector 24, an inert gas inlet connector 25, an inert gas outlet connector 26, and an activation liquid outlet connector 27 from top to bottom, which are used to connect with the pipes on the operation box 23 to facilitate the introduction of raw materials. The inner middle of the reactor 15 is equipped with a uniform material distribution mechanism 35, which is used to keep the activation liquid inside the reactor 15 evenly distributed when the reactor 15 is rotating. A pressure regulating valve 36 is installed on one side of the bottom of the reactor 15 to control the gas pressure inside the reactor 15.

[0052] Specifically, the linear motion module 22 controls the operation box 23 to move, so that the activation liquid inlet pipe 17 and the inert gas inlet pipe 18 are connected to the activation liquid inlet connector 24 and the inert gas inlet connector 25 respectively, and the raw materials are introduced into the reactor 15. Then, the linear motion module 22 controls the operation box 23 to move backward, and at the same time, the electric valve 21 controls all pipes to be closed, and the reaction process can begin.

[0053] In this embodiment, a drive motor 4 is installed on the lower right side of the upright plate 2. The drive end of the drive motor 4 passes through the inner bottom of the upright plate 2 and is fixedly connected to a second drive pulley 5. A second driven pulley 6 is installed on the left side of the rotating shaft 3. The outer diameters of the second drive pulley 5 and the second driven pulley 6 are connected by a second transmission belt 7.

[0054] Specifically, the second driving pulley 5 is driven by the drive motor 4, and the second drive belt 7 and the second driven pulley 6 drive the rotating shaft 3 to rotate, thereby driving the mounting frame 9 and the reaction vessel 15 to rotate circumferentially, thereby increasing the activation reaction rate.

[0055] Furthermore, a driving bevel gear 8 is fixedly connected to the upper right side of the upright plate 2. The driving bevel gear 8 is fixed on the upright plate 2, and the rotating shaft 3 passes through its center but does not contact it. The inner bottom left side of the mounting frame 9 is connected to a transmission shaft 10 through a movable bearing. A driven bevel gear 11 is installed at the bottom end of the transmission shaft 10. One side of the bottom end of the driven bevel gear 11 is meshed with the top of the driving bevel gear 8 to facilitate motion transmission. The top end of the transmission shaft 10 is fixedly connected to a first driving pulley 12. Rotating disks 16 are installed at both the upper and lower ends of the reactor 15 for connection and fixation, and can be disassembled to facilitate removal of the reactor 15. The upper and lower ends of the rotating disks 16 are movably connected to the inner wall of the mounting frame 9 through connecting rods, and the top end of the upper connecting rod is also fixedly connected to a first driven pulley 13. The outer diameters of the first driven pulley 13 and the first driving pulley 12 are connected through a first transmission belt 14.

[0056] Specifically, while the mounting frame 9 is rotating, it drives the first driving pulley 12 to rotate through the action of the driving bevel gear 8 and the driven bevel gear 11. Through the transmission of the first transmission belt 14 and the first driven pulley 13, it drives the reactor 15 to rotate. The reaction rate can be greatly accelerated by the rotation of the reactor 15 around the horizontal axis and its own rotation.

[0057] Furthermore, electric valves 21 are installed on the outer diameters of the activating liquid inlet pipe 17, the inert gas inlet pipe 18, the inert gas outlet pipe 19, and the activating liquid outlet pipe 20 to control the material conveying switch. Conical sealing plugs 28 are provided at the ends of the activating liquid inlet connecting pipe 24, the inert gas inlet connecting pipe 25, the inert gas outlet connecting pipe 26, and the activating liquid outlet connecting pipe 27 to improve the sealing performance during material conveying. At the same time, the inner openings of the activating liquid inlet pipe 17, the inert gas inlet pipe 18, the inert gas outlet pipe 19, and the activating liquid outlet pipe 20 are also tapered to further improve the sealing performance during docking.

[0058] Furthermore, the right end of the activation liquid inlet connector 24 extends into the operating box 23 and is installed at the output end of the activation liquid pump 29 for introducing activation liquid. The right end of the inert gas inlet connector 25 extends into the operating box 23 and is installed at the output end of the inert gas compressor 30 for introducing compressed inert gas. The right end of the inert gas outlet connector 26 extends into the operating box 23 and is installed at the output end of the inert gas recovery pump 31. The right end of the activation liquid outlet connector 27 extends into the operating box 23 and is positioned above the activation liquid receiving tray 32 for recovering activation liquid.

[0059] Furthermore, the left end of the activation liquid inlet pipe 17 extends into the interior of the reactor 15 and is installed at one end of the water ring 33. Several atomizing nozzles 34 are evenly installed at the bottom end of the water ring 33. Through the action of the water ring 33 and the atomizing nozzles 34, the activation liquid can be evenly sprayed into the reactor 15.

[0060] Furthermore, the uniform feeding mechanism 35 includes a composite cone frame 3501, with a heat-conducting frame 3503 fixedly connected to the middle of the composite cone frame 3501. The surface of the composite cone frame 3501 is uniformly provided with several uniform feeding holes 3502, and an electric heater 3504 is installed on one side of the middle of the heat-conducting frame 3503. The composite cone frame 3501 consists of two cones. Through the uniform feeding holes 3502 on its surface, the activation liquid moves up and down after passing through the uniform feeding holes 3502 when the reactor 15 rotates, thereby maintaining the uniform distribution of the activation liquid inside the reactor 15. This increases the activation reaction rate by increasing the contact area, while the electric heater 3504 effectively controls the heat inside the reactor 15.

[0061] The method for activating a hydrogenation catalyst using the above-mentioned hydrogenation catalyst activation device includes the following steps:

[0062] Step 1: The linear motion module 22 controls the operation box 23 to move, so that the activation liquid inlet pipe 17 and the inert gas inlet pipe 18 are connected to the activation liquid inlet connector 24 and the inert gas inlet connector 25 respectively. Then the activation liquid pump 29 introduces activation liquid into the reaction vessel 15, and the inert gas compressor 30 introduces inert gas into the reaction vessel 15.

[0063] Step 2: The electric heater 3504 controls the heat conduction frame 3503 to start heating up. The activation liquid is sprayed onto the material leveling mechanism 35 through the water ring 33 and the atomizing nozzle 34. The linear motion module 22 controls the operation box 23 to move backward, and at the same time the electric valve 21 controls all pipes to be in the closed state.

[0064] Step 3: The drive motor 4 drives the second active pulley 5 to rotate. Through the transmission of the second transmission belt 7 and the second driven pulley 6, the shaft 3 rotates, thereby causing the mounting frame 9 and the reactor 15 to rotate circumferentially. At the same time, as the mounting frame 9 rotates, it drives the first active pulley 12 to rotate through the action of the active bevel gear 8 and the driven bevel gear 11. Through the transmission of the first transmission belt 14 and the first driven pulley 13, the reactor 15 rotates, and the activation reaction begins.

[0065] Step 4: After the reaction is completed, the linear motion module 22 controls the operation box 23 to approach the reactor 15 again to connect all the pipes. The electric valve 21 is opened, the inert gas recovery pump 21 recovers the gas, and the solution after the reaction enters the activation liquid receiving tray 32 through the activation liquid outlet pipe 27 to complete the collection action.

[0066] Furthermore, the activation solution contains a porous support composition, which consists of a porous support, sulfurized oil, organic solvent and additives. The inert gas includes one or more of nitrogen, argon, helium, carbon dioxide and water vapor. The inlet temperature of the reactor 15 is controlled at 130-160℃, the volume hourly space velocity is 0.2-20 h⁻¹, the final temperature of the reactor 15 is 180-280℃, and the reaction time is 5-8 h.

[0067] Specifically, the additives, organic solvents and other additives are introduced into the porous support through impregnation, which shares some of the heat, thereby dispersing the heat released by the hydrogenation catalyst during the activation process and avoiding excessively high local temperatures in the hydrogenation catalyst bed, which would affect the catalyst performance.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
