Description

Technical Field

[0001] This application relates to the field of aviation fuel technology, and in particular to a sustainable aviation fuel synthesis reactor and process. Background Technology

[0002] In the production route of sustainable aviation fuel (SAF), grafting C3–C4 light olefins onto bio-based C6–C8 aromatics through alkylation to increase molecular weight to C9–C16 is a key step to meet the carbon number requirements of aviation kerosene and increase the aromatic content. This reaction is a typical gas-liquid-solid three-phase catalytic reaction, and the mass transfer resistance between the gas and liquid phases is extremely large, which has become the core bottleneck restricting efficiency.

[0003] However, the inventors have discovered at least the following technical problems in the related technology:

[0004] Existing conventional reactors used for alkylation reactions generally suffer from problems such as premature gas-liquid mixing, unreasonable contact methods, easy occurrence of side reactions and self-polymerization, affecting selectivity and catalyst life, poor gas-liquid dispersion, insufficient phase interface area, and inability to meet the specific requirements of SAF alkylation carbon enrichment, making it difficult to achieve high mass transfer requirements at the same time. Summary of the Invention

[0005] One objective of this application is to provide a sustainable aviation fuel synthesis reactor and process, which at least addresses the problems commonly found in traditional reactors, such as premature gas-liquid mixing, side reactions, and self-polymerization, which affect selectivity and catalyst life.

[0006] To achieve the above objectives, some embodiments of this application provide the following aspects:

[0007] In a first aspect, some embodiments of this application provide a sustainable aviation fuel synthesis reactor, including a reactor shell. A gas phase input pipe is fixedly connected to the bottom of the reactor shell. A Venturi tube is fixedly connected to the inner wall of the bottom of the reactor shell. The Venturi tube is configured from bottom to top as a contraction section, a throat, and an expansion section. The top of the gas phase input pipe is fixedly connected to the contraction section of the Venturi tube. A liquid phase input pipe is fixedly connected to the bottom side wall of the reactor shell. One end of the liquid phase input pipe is fixedly connected to an outer ring dispersion channel. The inner wall of the outer ring dispersion channel is fitted onto the outer wall of the Venturi tube. The inner wall of the outer ring dispersion channel is uniformly provided with spiral shear grooves. One end of the liquid phase input pipe is located at an eccentric position in the outer ring dispersion channel. An adjustment component is installed at the bottom of the reactor shell. A catalytic component is installed in the middle of the reactor shell. A three-phase separation component is installed at the top of the reactor shell.

[0008] Secondly, some embodiments of this application also provide a sustainable aviation fuel synthesis process, including the following steps:

[0009] A gaseous feedstock containing C3–C4 olefins is introduced into a Venturi tube through a gas phase input pipe. The feedstock is accelerated axially upward through the constriction section of the Venturi tube and cavitation occurs in the throat to form a high-speed micron-sized bubble jet.

[0010] The liquid feedstock containing C6–C8 aromatic hydrocarbons is eccentrically and tangentially introduced into the outer ring dispersion channel through the liquid input pipe. Under the action of the spiral shear groove, a high-speed swirling flow is formed, and the two phases are dispersed and mixed by perpendicular orthogonal collision in the mixing zone.

[0011] The heat exchange jackets on the outer walls of the Venturi tube and the outer ring dispersion channel respectively control the temperature of the gas phase and the liquid phase.

[0012] The particle size signal is collected by an online particle size analyzer and transmitted to the control box. The control box drives the electric push rod to move the annular adjustment cone, thereby adjusting the gap of the annular coupling flow channel and the droplet size.

[0013] The mixture enters the catalytic bed, undergoes preliminary reaction by the inner catalyst layer, and completes deep reaction after liquid distribution by the perforated baffle plate; waveguide rod type acoustic emission sensor monitors hot spots, and array nozzles spray coolant to cool down.

[0014] After the reaction, the gas-liquid mixture impacts the annular baffle. The liquid phase enters the annular liquid phase collection frame and is discharged through the liquid phase output pipe. The gas phase is demisted by the demister and discharged through the gas phase output pipe. After being regulated by the circulation pipe and the electronic back pressure regulating valve, it flows back to the gas phase input pipe.

[0015] The pressure sensor transmits the pressure signal to the control box to achieve closed-loop pressure control; the drive motor drives the rotating shaft and stirring blades to rotate, which disperses the disturbance of materials in the mixing zone. The rotating shaft drives the rotating shaft and fan blades to rotate through the drive gear, transmission tooth belt, driven gear, drive bevel gear and driven bevel gear, forming a negative pressure at the top of the reactor shell to enhance gas-liquid separation.

[0016] Compared with related technologies, the solution provided in this application achieves high dispersion and mixing of the gas and liquid phases. The gas phase feed containing C3–C4 olefins is injected into the Venturi tube through the gas phase input pipe and flows upward along the axial direction of the Venturi tube to form a high-speed micron-sized bubble jet. The liquid phase feed containing C6–C8 aromatic hydrocarbons is eccentrically and tangentially introduced into the outer ring dispersion channel through the liquid phase input pipe. Under the action of the spiral shear groove, a high-speed swirling flow is formed. The gas phase flows inside the Venturi tube and the liquid phase flows inside the outer ring dispersion channel. The axial jet gas phase ejected from the Venturi tube collides perpendicularly and orthogonally with the swirling liquid phase output from the top of the outer ring dispersion channel. Therefore, the two phases are completely isolated and have no contact before entering the mixing zone, which avoids side reactions, self-agglomeration and coking, and local overheating caused by premature contact of the feed.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] First Embodiment

[0028] The first embodiment relates to a sustainable aviation fuel synthesis reactor. For example... Figures 1-7 As shown, the core of this embodiment is: a reactor shell 1, a gas phase input pipe 2 fixedly connected to the bottom of the reactor shell 1, a venturi tube 201 fixedly connected to the inner wall of the bottom of the reactor shell 1, the venturi tube 201 being arranged from bottom to top as a contraction section, a throat and an expansion section, the top of the gas phase input pipe 2 fixedly connected to the contraction section of the venturi tube 201, a liquid phase input pipe 202 fixedly connected to the bottom side wall of the reactor shell 1, an outer ring dispersion channel 203 fixedly connected to one end of the liquid phase input pipe 202, the inner wall of the outer ring dispersion channel 203 being sleeved on the outer wall of the venturi tube 201, a spiral shear groove 204 uniformly opened on the inner wall of the outer ring dispersion channel 203, one end of the liquid phase input pipe 202 being set at an eccentric position of the outer ring dispersion channel 203, an adjustment component installed at the bottom of the reactor shell 1, a catalytic component installed in the middle of the reactor shell 1, and a three-phase separation component installed at the top of the reactor shell 1.

[0029] Specifically, a gaseous feedstock containing C3–C4 olefins is introduced into a Venturi tube 201 through a gas phase input pipe 2, flowing upward along the axial direction of the Venturi tube 201. It is accelerated through the constriction section and cavitation in the throat of the Venturi tube 201, forming a high-speed micron-sized bubble jet. A liquid feedstock containing C6–C8 aromatic hydrocarbons is introduced eccentrically and tangentially into the outer ring dispersion channel 203 through a liquid phase input pipe 202, forming a high-speed swirling flow under the action of a spiral shear groove 204. The gas phase flows inside the Venturi tube 201, and the liquid phase flows inside the outer ring dispersion channel 203. The bottom of the catalytic assembly is connected to the Venturi tube. The top of tube 201 forms a mixing zone. The axial jet gas phase ejected from the Venturi tube 201 collides perpendicularly and orthogonally with the swirling liquid phase output from the top of the outer ring dispersion channel 203, achieving high dispersion and mixing of the gas and liquid phases. The two phases are completely isolated and have no contact before entering the mixing zone, thus avoiding side reactions, self-agglomeration and coking, and local overheating caused by premature contact of raw materials. The regulating component changes the single-sided gap width of the annular coupling channel to adapt to different particle size requirements. The catalytic component ensures high selectivity of the C9–C16 target product, and the three-phase separation component separates the gas and liquid phases.

[0030] like Figures 1-4 As shown, the adjustment assembly includes symmetrically arranged electric push rods 205. The outer walls of the electric push rods 205 are all installed on the inner wall of the reactor shell 1. The output end of the electric push rods 205 is fixedly connected to the mounting plate 206. An annular adjustment cone 207 is fixedly connected to one side of the two mounting plates 206. The outer wall of the annular adjustment cone 207 is set on the inner wall of the outer ring dispersion channel 203. The inner wall of the annular adjustment cone 207 is set on the outer wall of the Venturi tube 201. Heat exchange jackets 208 are provided on the outer walls of the Venturi tube 201 and the outer walls of the outer ring dispersion channel 203. An online particle size analyzer 209 is installed on the outer wall of the reactor shell 1. The sampling end of the online particle size analyzer 209 is set at the top of the outer ring dispersion channel 203 and the Venturi tube 201.

[0031] Specifically, the heat exchange jacket 208 of the Venturi tube 201 is used to preheat the gaseous feedstock of C3–C4 olefins to a critical temperature range below their self-polymerization temperature. The heat exchange jacket 208 of the outer wall of the outer ring dispersion channel 203 is used to precool the liquid feedstock of C6–C8 aromatics to a temperature range where its viscosity and surface tension are suitable for orthogonal collision and breakup, so that the two phases reach the optimal reaction temperature range. The gap between the Venturi tube 201 and the outer ring dispersion channel 203 forms an annular coupling flow channel. An online particle size analyzer 209 is set in the mixing zone. The sampling end directly collects the micro-interface system, monitors the droplet particle size distribution in real time and outputs a signal. The particle size signal is transmitted to the control box 1001. According to the set particle size target, the control system automatically drives the electric push rod 205 to move the annular adjusting cone 207 up and down, changing the width of the gap on one side of the annular coupling flow channel. When the gap increases, the shear force decreases, resulting in larger droplet particle size. When the gap decreases, the shear force increases, resulting in smaller droplet particle size.

[0032] like Figures 1-3 , Figures 5-6 As shown, the catalytic assembly includes symmetrically arranged catalytic beds 3. The outer wall of the catalytic bed 3 is installed on the inner wall of the reactor shell 1. The inner wall of the catalytic bed 3 is equipped with an inner catalyst 301, a perforated baffle 302, an array nozzle 303, and a waveguide rod type acoustic emission sensor 304 from bottom to top.

[0033] Specifically, the mixture enters the catalyst bed 3 upwards, first undergoing a preliminary alkylation reaction through the inner catalyst 301 to remove impurities and buffer the reaction intensity. Then, it passes through the perforated baffle 302 for uniform liquid distribution and enters the main catalytic zone to complete the deep shape-selective reaction, ensuring high selectivity for the C9–C16 target products. Waveguide rod type acoustic emission sensors 304 are arranged inside the catalyst bed 3 to monitor catalyst particle friction, breakage, coking, and temperature fluctuation signals, identify local hot spots in real time, and upload the data to the control system. When a hot spot trend is detected, the array nozzle 303 is connected to the outside environment and immediately sprays a small amount of coolant into the hot spot area to achieve millisecond-level local cooling. Combined with the heat exchange jacket 208 for continuous heat transfer, it completely suppresses runaway temperature, coking, and catalyst deactivation.

[0034] like Figures 1-3 As shown, the three-phase separation assembly includes an annular baffle 4. The outer wall of the annular baffle 4 is fixedly connected to the inner wall of the reactor shell 1. An annular liquid phase collection frame 401 and a demister 402 are respectively provided directly below and above the annular baffle 4. The outer walls of the annular liquid phase collection frame 401 and the demister 402 are both fixedly connected to the outer wall of the reactor shell 1.

[0035] A liquid phase output pipe 5 is installed on the outer wall of the annular liquid phase collection frame 401. The outer wall of the liquid phase output pipe 5 is fixedly connected to the reactor shell 1. A gas phase output pipe 501 is fixedly connected to the top of the reactor shell 1. A circulation pipe 502 is fixedly connected to the outer wall of the gas phase output pipe 501. One end of the circulation pipe 502 is fixedly connected to the outer wall of the gas phase input pipe 2.

[0036] A pressure sensor 6 is installed on the top inner wall of the reactor shell 1, and an electronic back pressure regulating valve 601 is installed inside the circulation pipe 502.

[0037] Specifically, the gas-liquid mixture after the reaction rises and impacts the lower surface of the annular baffle 4. Due to its large inertia, the liquid phase is intercepted and drips down along the slope of the baffle, entering the annular liquid phase collection frame 401 directly below and being continuously discharged through the liquid phase output pipe 5. The gas phase, after removing large droplets, continues to rise and passes through the demister screen 402 for fine demisting, further removing tiny droplets to ensure gas phase purity. The purified gas phase is discharged through the gas phase output pipe 501. After the pressure and flow rate are regulated by the circulation pipe 502 and the electronic back pressure regulating valve 601, it flows back to the gas phase input pipe 2 to participate in the reaction again, realizing the efficient recycling of gas phase raw materials and reducing consumption and emissions.

[0038] Meanwhile, the pressure sensor 6 on the inner wall of the top of the reactor shell 1 monitors the system pressure in real time and transmits the pressure signal to the control box 1001. This forms a feedforward compensation control with the electronic back pressure regulating valve 601 in the circulation pipe 502, automatically adjusting the circulating gas volume and system pressure to ensure long-term stability of mixing intensity, reaction pressure and separation efficiency.

[0039] like Figures 1-3 , Figure 5 , Figure 7 As shown, a mounting frame 7 is fixedly connected to the outer wall of the gas phase output pipe 501, and a rotating shaft 701 is rotatably connected inside the mounting frame 7. The outer wall of the rotating shaft 701 is set on the top of the reactor shell 1, and fan blades 702 are uniformly fixedly connected to one end of the rotating shaft 701.

[0040] A fixed frame 8 is fixedly connected to one side of the reactor shell 1. A drive motor 801 is installed inside the fixed frame 8. A rotating shaft 802 is fixedly connected to the output end of the drive motor 801. The outer wall of the rotating shaft 802 is rotatably connected to the reactor shell 1. Stirring blades 803 are uniformly fixedly connected to the outer wall of the rotating shaft 802. A drive gear 9 is fixedly connected to the outer wall of the rotating shaft 802. A transmission toothed belt 901 is meshed with the outer wall of the drive gear 9. A driven gear 902 is meshed with the inner wall of one end of the transmission toothed belt 901. A support shaft 903 is fixedly connected to the inner wall of the driven gear 902. The outer wall of the support shaft 903 is rotatably connected to the mounting frame 7 and the fixed frame 8. A drive bevel gear 904 is fixedly connected to the outer wall of one end of the support shaft 903. A driven bevel gear 905 is meshed with the tooth end of the drive bevel gear 904. The inner wall of the driven bevel gear 905 is fixedly connected to the outer wall of the rotating shaft 701.

[0041] Specifically, by starting the drive motor 801, its output end drives the rotating shaft 802 to rotate. The rotating shaft 802 drives the stirring blades 803 to rotate. The stirring blades 803 agitate the gas and liquid in the mixing area, forcibly disturbing, shearing, and uniformly dispersing the orthogonally coupled gas-liquid mixture. This eliminates dead zones in the flow field, local uneven concentration, and large droplet aggregation, making the microdroplet particle size distribution more uniform and the mixing more thorough. This further improves the phase interface contact efficiency and reaction stability. At the same time, the rotating shaft 802 drives the drive gear 9 to rotate, which causes the transmission belt 901 to drive the driven gear 902 to rotate, which causes the support shaft 903 to rotate. The support shaft 903 drives the drive bevel gear 904 to rotate, which causes the driven bevel gear 905 to drive the rotating shaft 701 to rotate. The rotating shaft 701 drives the fan blades 702 to rotate. The fan blades 702 create a negative pressure at the top of the reactor shell 1, promoting the orderly rise of the gas phase and the smooth sedimentation of the liquid phase, enhancing the gas-liquid separation effect, and improving the system's flow capacity and operational stability.

[0042] like Figure 1 As shown, a fixing plate 10 is fixedly connected to the outer wall of the reactor shell 1, and a control box 1001 is installed on the top of the fixing plate 10. The control box 1001 is electrically connected to the electrical components in the reactor and is used to control the operation of the electrical components in the reactor.

[0043] Specifically, the control box 1001 serves as the central control unit, uniformly receiving detection signals from the online particle size analyzer 209, pressure sensor 6, and waveguide rod type acoustic emission sensor 304, and automatically outputting control commands to adjust the electric push rod 205, electronic back pressure regulating valve 601, drive motor 801, and array nozzle 303, thereby achieving intelligent operation.

[0044] Second Embodiment

[0045] The second embodiment relates to a sustainable aviation fuel synthesis process, including the following steps:

[0046] A gaseous feedstock containing C3–C4 olefins enters a venturi tube 201 through a gas phase input pipe 2. The feedstock is accelerated axially upward through the contraction section of the venturi tube 201 and cavitation occurs in the throat to form a high-speed micron-sized bubble jet.

[0047] The liquid feedstock containing C6–C8 aromatic hydrocarbons enters the outer ring dispersion channel 203 eccentrically and tangentially through the liquid input pipe 202. Under the action of the spiral shear groove 204, a high-speed swirling flow is formed, and the two phases are dispersed and mixed by perpendicular orthogonal collision in the mixing zone.

[0048] The heat exchange jacket 208 on the outer wall of the Venturi tube 201 and the outer ring dispersion channel 203 respectively controls the temperature of the gas phase and the liquid phase.

[0049] The particle size signal is collected by the online particle size analyzer 209 and transmitted to the control box 1001. The control box 1001 drives the electric push rod 205 to move the annular adjustment cone 207 to adjust the gap of the annular coupling flow channel and the droplet size.

[0050] The mixture enters the catalytic bed 3, undergoes preliminary reaction by the inner catalyst 301, and completes deep reaction after liquid distribution by the perforated baffle 302; the waveguide rod type acoustic emission sensor 304 monitors hot spots, and the array nozzle 303 sprays coolant to cool down.

[0051] After the reaction, the gas-liquid mixture impacts the annular baffle 4. The liquid phase enters the annular liquid phase collection frame 401 and is discharged through the liquid phase output pipe 5. The gas phase is demisted by the demister 402 and discharged through the gas phase output pipe 501. After being regulated by the circulation pipe 502 and the electronic back pressure regulating valve 601, it flows back to the gas phase input pipe 2.

[0052] Pressure sensor 6 transmits pressure signals to control box 1001 to achieve closed-loop pressure control; drive motor 801 drives shaft 802 and stirring blade 803 to rotate, disturbing and dispersing materials in the mixing zone. Shaft 802 drives shaft 701 and fan blade 702 to rotate via drive gear 9, transmission belt 901, driven gear 902, drive bevel gear 904, and driven bevel gear 905, forming negative pressure at the top of reactor shell 1 to enhance gas-liquid separation.

10. A sustainable aviation fuel synthesis process, characterized in that: An application of a sustainable aviation fuel synthesis reactor according to any one of claims 1-9 includes the following steps: A gaseous feedstock containing C3–C4 olefins is introduced into a venturi tube (201) through a gas phase input pipe (2). The feedstock is accelerated axially upward through the contraction section of the venturi tube (201) and cavitation occurs in the throat to form a high-speed micron-sized bubble jet. The liquid feedstock containing C6–C8 aromatic hydrocarbons is eccentrically and tangentially introduced into the outer ring dispersion channel (203) through the liquid input pipe (202). Under the action of the spiral shear groove (204), a high-speed swirling flow is formed, and the two phases are dispersed and mixed by perpendicular orthogonal collision in the mixing zone. The heat exchange jacket (208) on the outer wall of the Venturi tube (201) and the outer ring dispersion channel (203) respectively controls the temperature of the gas phase and the liquid phase; The particle size signal is collected by the online particle size analyzer (209) and transmitted to the control box (1001). The control box (1001) drives the electric push rod (205) to move the annular adjustment cone (207) to adjust the gap of the annular coupling flow channel and the droplet size. The mixture enters the catalyst bed (3), undergoes preliminary reaction by the inner catalyst (301), and completes deep reaction after liquid distribution by the perforated baffle (302); the waveguide rod type acoustic emission sensor (304) monitors hot spots, and the array nozzle (303) sprays coolant to cool down; After the reaction, the gas-liquid mixture impacts the annular baffle (4), the liquid phase enters the annular liquid phase collection frame (401) and is discharged through the liquid phase output pipe (5), and the gas phase is discharged through the gas phase output pipe (501) after being demisted by the demister (402). After being regulated by the circulation pipe (502) and the electronic back pressure regulating valve (601), it flows back to the gas phase input pipe (2). The pressure sensor (6) transmits the pressure signal to the control box (1001) to realize closed-loop pressure control; the drive motor (801) drives the rotating shaft (802) and the stirring blade (803) to rotate, which disperses the disturbance of the material in the mixing zone. The rotating shaft (802) drives the rotating shaft (701) and the fan blade (702) to rotate through the drive gear (9), the transmission belt (901), the driven gear (902), the drive bevel gear (904), and the driven bevel gear (905), which forms a negative pressure at the top of the reactor shell (1) to enhance gas-liquid separation.
