Description

Technical Field

[0001] The present invention belongs to the field of hydrogen production, and in particular relates to a method, a device and a method for preparing aviation fuel by hydrogenating biomass raw materials. Background Art

[0002] The installed capacity and capacity of existing hydrogen production stations are mostly fixed. When new energy is connected to hydrogen production for power supply, when new energy power generation such as photovoltaic and wind turbines is connected, the fixed modular hydrogen production device cannot absorb the new energy electricity. Due to the installed capacity and capacity limitations of the hydrogen production station, it cannot absorb the new energy electricity, resulting in a waste of clean energy; when the fixed modular hydrogen production device is under maintenance, the fixed hydrogen production station cannot utilize new energy electricity on the one hand, and on the other hand, it causes a decrease in hydrogen production capacity, affecting the stable supply of hydrogen.

[0003] However, in the cold winter, due to snow accumulation and low temperatures, when solar or wind power is abandoned, it is difficult to connect the PEM hydrogen production equipment to the power supply when the photovoltaic system is coupled with the PEM hydrogen production equipment. For example, when using a cable connection, the cable needs to be manually dragged and crimped to the cable terminal board, which is time-consuming and difficult to operate. In addition, when using a vehicle-mounted hydrogen production device to produce hydrogen, due to the deviation in the positioning of the wheels and the baffle, the distance between the first power device or the second power connection unit of the PEM hydrogen production equipment and the power control cabinet deviates. When manual operation is used to connect the power supply, the cable length is insufficient due to the distance deviation, or the cable terminal holes do not match, making it impossible to screw the connecting cable terminal board between the PEM hydrogen production equipment and the power control cabinet.

[0004] With the sustained and stable growth of my country's economy, the aviation industry has developed rapidly. my country has become the world's second largest aviation country, and the demand for aviation kerosene (abbreviated as aviation kerosene) is also increasing year by year. At present, aviation kerosene (generally referring to C8-C16 alkanes) as aviation turbine engine fuel is mainly produced by using atmospheric and vacuum distillation units to preliminarily process crude oil, and then subjecting the fractionated products to secondary processing such as catalytic cracking. However, with the prominence of energy and environmental issues, especially the intensification of the global greenhouse effect, and in order to achieve sustainable development of the aviation industry, seeking and developing new energy has become a research focus. Biomass aviation kerosene can reduce CO2 emissions by more than 70% during the production process. Common biomass aviation kerosene production processes mainly include hydrogenation, gasification-Fischer-Tropsch synthesis, biomass thermal cracking and catalytic cracking, among which hydrogenation is more commonly used. Using new energy to produce hydrogen and apply it to aviation kerosene preparation is a problem that needs to be solved to improve the renewable cycle of resources. Summary of the invention

[0005] The purpose of the present invention is to provide a method, device and method for preparing aviation kerosene by hydrogenating biomass raw materials, so as to realize the scheduling of hydrogen produced by distributed hydrogen production stations, which not only makes full use of photovoltaic and wind energy, but also utilizes biomass gas to synthesize aviation kerosene to avoid the consumption of coal and gas and improve the utilization rate of clean energy.

The aviation fuel preparation system includes an aviation fuel preparation center 9, and multiple hydrogen production stations are arranged around the aviation fuel preparation center 9.

[0065] The north side of the aviation fuel preparation center 9 is located in an area rich in wind resources, so wind turbines are installed in multiple hydrogen production stations on the north side of the aviation fuel preparation center 9, and the wind turbines generate electricity to provide power for the hydrogen production stations.

[0066] The south side of the aviation fuel preparation center 9 is located in an area rich in photovoltaic resources, so photovoltaic panels are installed in multiple hydrogen production stations on the south side of the aviation fuel preparation center 9, and the photovoltaic panels generate electricity to provide power for the hydrogen production stations.

[0067] In addition, outside the wind and photovoltaic resource-rich areas of the aviation fuel preparation center 9, photovoltaic panels and / or wind turbines are installed in the remaining hydrogen production stations, and the photovoltaic panels and / or wind turbines generate electricity to provide power for the hydrogen production stations.

[0068] A hydrogen production station a1 is set up at the farthest point on the north side of the aviation fuel preparation center 9. The wind resources are the most abundant at the hydrogen production station a1, so the wind power hydrogen production capacity is the largest. The distance from the hydrogen production station a1 to the aviation fuel preparation center 9 is R1.

[0069] A hydrogen production station b1 is set up at the farthest point on the south side of the aviation fuel preparation center 9. The solar energy resources are the most abundant at the hydrogen production station b1, so the photovoltaic hydrogen production capacity is the largest. The distance from the hydrogen production station b1 to the aviation fuel preparation center 9 is R2.

[0070] The wind power hydrogen production circle is formed with hydrogen production station a1 as the center and R1 as the radius. The wind power hydrogen production circle contains multiple first hydrogen production stations a 1i , i is an integer greater than 1, Figure 3 The case where i is 3 is shown in FIG. 1 , but i can be greater than 3, for example, 5, 10, 20, 30, 50, 100, etc. The first hydrogen production station a 1i Wind turbines are installed to generate electricity to provide power for the hydrogen production station. The wind resources within the wind power hydrogen production circle are stable.

[0071] A photovoltaic hydrogen production circle is drawn with hydrogen production station b1 as the center and R2 as the radius. The photovoltaic hydrogen production circle contains multiple second hydrogen production stations b 1j , j is an integer greater than 1, Figure 3 The case where j is 3 is shown in FIG. 1 , but j can be greater than 3, for example, 8, 10, 16, 24, 36, 48, etc. The second hydrogen production station b 1i Photovoltaic panels are installed to generate electricity to provide power for the hydrogen production station.

[0072] There are several third hydrogen production stations outside the wind power hydrogen production circle and photovoltaic hydrogen production circle. 1k , k is an integer greater than 1, Figure 3The case where k is 4 is shown in FIG. 1 , but k can be greater than 4, for example, 10, 15, 20, 25, 30, etc. The third hydrogen production station c 1k The distribution of wind and photovoltaic resources is uneven and fluctuates greatly.

[0073] Hydrogen production station a1, hydrogen production station b1, first hydrogen production station a 1i 、The second hydrogen production station b 1j and the third hydrogen production station c 1k It includes skid-mounted modular hydrogen production equipment and / or fixed modular hydrogen production equipment.

[0074] The fixed modular hydrogen production device includes an electrolyzer 100, hydrogen production auxiliary equipment 101, purification equipment 102, a water supply tank 104, a water supply pump 105, a catalyst box 106, a power conversion device 107, a transformer 108, a control cabinet 103 and a hydrogen storage area 109. The water supply tank 104, the catalyst box 106 and the water supply pump 105 are connected in sequence and connected to the electrolyzer 100 to provide electrolyte; the control cabinet 103 is connected to the power conversion device 107 and the transformer 108 to monitor and control the power system, and the power of the transformer 8 is converted by the power conversion device 107 to supply power to the electrolyzer 100.

[0075] The hydrogen in the electrolyzer 100 is transported to the hydrogen production auxiliary equipment 101 and the purification equipment 102 through an underwater gas pipeline for processing to produce high-purity hydrogen, which is then transported to the hydrogen storage area 109 through a gas pipeline 1091 for storage.

[0076] See also Figure 1-Figure 4 The skid-mounted modular hydrogen production device is a vehicle-mounted PEM hydrogen production coupling device 4, and the vehicle-mounted PEM hydrogen production coupling device 4 is movable.

[0077] The site of the fixed modular hydrogen production device is provided with a skid-mounted parking space 110, which is specifically divided into skid-mounted parking space 1, parking space 2, parking space 3, ..., parking space n1, where n1 is a positive integer. The skid-mounted parking space is used for parking the vehicle-mounted PEM hydrogen production coupling device 4. The fixed modular hydrogen production device and the skid-mounted modular hydrogen production device respectively utilize the photovoltaic or wind power energy in the basic hydrogen production station and the regulating hydrogen production station to produce hydrogen.

[0078] like Figure 4-Figure 11 As shown, the new energy photovoltaic system 1, the power control cabinet 2, the hydrogen production control switch cabinet 3 and the PEM hydrogen production equipment 4, the new energy photovoltaic system 1 generates electricity and converges it to the power control cabinet 2, and the hydrogen production control switch cabinet 3 controls the power on and off between the power control cabinet 2 and the PEM hydrogen production equipment 4. The power control cabinet 2 and the hydrogen production control switch cabinet 3 are located at the site where the fixed modular hydrogen production device of the hydrogen production station is located.

[0079] Optionally, the PEM hydrogen production equipment 4 is also a vehicle-mounted PEM hydrogen production coupling device 4, which includes a PEM hydrogen production device 7, a first power device 5, a second power device 6 and a baffle 8, the first power device 5 has a first power connection unit 51, and the second power device 6 has a second power connection unit 61.

[0080] Modularization means that the vehicle-mounted PEM hydrogen production coupling device 4 is driven into the skid-mounted parking space set up in the area where the modular hydrogen production device is fixed like multiple modules. Only one vehicle-mounted PEM hydrogen production coupling device 4 can work, or multiple vehicle-mounted PEM hydrogen production coupling devices 4 can work simultaneously.

[0081] like Figure 5 As shown, the PEM hydrogen production device 7 includes a hydrogen production unit, a power input terminal 71 and a hydrogen storage unit, and the first power connection unit 51 or the second power connection unit 61 is electrically connected to the power input terminal 71.

[0082] Hydrogen production unit: Hydrogen is produced by direct decomposition of water, which can be achieved in a variety of ways: the water decomposition method for hydrogen production specifically includes electrolysis of water, photocatalytic decomposition of water, or thermochemical cycle decomposition of water. Use electricity to electrolyze water to generate hydrogen and oxygen; use solar energy, wind energy, or geothermal energy to decompose water to produce hydrogen through a thermochemical cycle; use light energy to directly decompose water through a catalyst to produce hydrogen. The produced hydrogen enters the hydrogen storage unit for storage. Hydrogen is mainly produced by decomposing water, and the implementation method can be, but is not limited to, photolysis of water, electrolysis of water, pyrolysis of water, etc.

[0083] Hydrogen storage unit: includes hydrogen storage material and hydrogen storage tank, which is provided with hydrogen inlet and hydrogen outlet, and the hydrogen storage material is located inside the hydrogen storage tank. The tank body of the hydrogen storage tank can be made of polytetrafluoroethylene material, stainless steel and other materials, which are characterized by high pressure resistance, anti-permeability and corrosion resistance.

[0084] Hydrogen storage materials mainly include the following categories: 1) Physical adsorption hydrogen storage materials - reversibly adsorbed on high specific surface area porous materials through physical action, such as carbon-based materials (graphite, activated carbon, carbon nanotubes) or inorganic porous materials (such as zeolite molecular sieves) and metal organic frameworks (MOFs), etc. The metal organic framework (MOF) is Cu2(L2)(H2O)2, IRMOF-11 or IRMOF-20, etc. 2) Metal hydride hydrogen storage materials - including light metal hydrides (such as Mg-based series, specifically single magnesium hydrogen storage materials, magnesium-based composite hydrogen storage materials and magnesium-based alloy hydrogen storage materials) or advanced alloy hydrides (such as LaNi5 or TiFe alloys, etc.). 3) Chemical hydride hydrogen storage materials - including sodium aluminum hydride, lithium aluminum hydride, calcium aluminum hydride, lithium nitrogen hydrogen system or ammonia borane, etc. 4) Organic liquid hydrogen storage materials - including aromatic ring compounds such as benzene, toluene, naphthalene and condensed heterocyclic compounds. The catalyst is a noble metal catalyst, a Ni catalyst, a homogeneous catalyst, or the like.

[0085] In the cold winter, due to snow accumulation and low temperatures, when solar or wind power is abandoned, it is difficult to connect the PEM hydrogen production equipment 4 to the power supply when the photovoltaic system 1 is coupled to the PEM hydrogen production equipment 4. For example, when a cable is used for connection, the cable needs to be manually dragged and crimped to the cable terminal board, which is time-consuming and difficult to operate. In addition, when hydrogen is produced using a vehicle-mounted hydrogen production device, due to the positioning deviation of the wheels and the baffle 8, the distance between the first power connection unit 51 or the second power connection unit 61 of the PEM hydrogen production equipment 4 and the power control cabinet 2 deviates. When manual operation is used to connect the power supply, the cable length is insufficient and cannot be connected due to the distance deviation, or the cable terminal holes do not match, making it impossible to screw the connecting cable terminal board between the PEM hydrogen production equipment 4 and the power control cabinet 2.

[0086] The present application sets up a hydrogen production control switch cabinet 3 between the PEM hydrogen production equipment 4 and the power control cabinet 2 to facilitate the automatic connection of the PEM hydrogen production equipment 4 to the power control cabinet 2, thereby reducing the problem of insufficient cable length for connection or mismatched cable terminal holes causing the inability to screw the connecting cable terminal board between the PEM hydrogen production equipment 4 and the power control cabinet 2.

[0087] Figure 7 This is a schematic diagram of the vehicle-mounted hydrogen production equipment and the baffle position according to an embodiment of the present invention, wherein Figure 7 Part 7a is when the wheels of the PEM hydrogen production equipment 4 are precisely positioned through the baffle 8, the first power connection unit 51 of the first power device 5 is directly opposite to the power interface 31 of the hydrogen production control switch cabinet 3; Figure 7 Part 7b shows that when the wheels of the PEM hydrogen production equipment 4 do not contact the baffle 8, a distance deviation occurs between the first power connection unit 51 of the first power device 5 and the power interface 31 of the hydrogen production control switch cabinet 3; Figure 7 Part 7c shows that when the wheels of the PEM hydrogen production equipment 4 exceed the baffle 8, a distance deviation occurs between the first power connection unit 51 of the first power device 5 and the power interface 31 of the hydrogen production control switch cabinet 3; Figure 7 Part 7d shows that when an angle deviation occurs between the wheel of the PEM hydrogen production equipment 4 and the baffle 8 , an angle deviation occurs between the first power connection unit 51 of the first power device 5 and the power interface 31 of the hydrogen production control switch cabinet 3 .

[0088] The first power connection unit 51 of the first power device 5 of the PEM hydrogen production equipment 4 has a telescopic rod 52 and L1~L3 three-phase terminals 53 located at the end of the telescopic rod 52. After the telescopic rod 52 extends out of the first power connection unit 51, it pushes the L1~L3 three-phase terminals 53 to contact the power terminals on the power interface 31 of the hydrogen production control switch cabinet 3 to provide power to the PEM hydrogen production equipment 4.

[0089] See also Figure 7Parts 7b-7d show that when there is a distance or angle deviation between the wheel of the PEM hydrogen production equipment 4 and the baffle 8, the contact between the telescopic rod 52 and the power terminal on the power interface 31 of the hydrogen production control switch cabinet 3 after extending out of the first power connection unit 51 will deviate, affecting the reliability of power supply.

[0090] Angle correction: The wheels of the PEM hydrogen production equipment 4 are positioned by the baffle 8 and then angle corrected. A first infrared distance sensor 54 and a second infrared distance sensor 55 are symmetrically arranged on the left and right sides of the first power connection unit 51. The distance between the first infrared distance sensor 54 and the second infrared distance sensor 55 is CD. The center lines of the first infrared distance sensor 54 and the second infrared distance sensor 55 are perpendicular to their installation planes on the first power device 5. The first infrared distance sensor 54 measures the distance between the PEM hydrogen production equipment 4 and the hydrogen production control switch cabinet 3 as AD. The second infrared distance sensor 55 measures the distance between the PEM hydrogen production equipment 4 and the hydrogen production control switch cabinet 3 as BC. A line parallel to the line segment CD through point A intersects the line segment BC at point E. After the telescopic rod 52 extends out of the first power connection unit 51, the deflection angle is ∠BAE=arc(tan((BC-AD) / CD)). Since BC>AD, the deflection direction is from the second infrared distance sensor 55 to the first infrared distance sensor 54.

[0091] Due to the distance or angle deviation between the wheel of the PEM hydrogen production equipment 4 and the baffle 8, as well as the displacement change in the vertical direction of the first power connection unit 51 caused by the wheel air pressure, after the angle correction, there is a vertical and horizontal deviation between the L1~L3 three-phase terminals 53 and the power terminals on the power interface 31 of the hydrogen production control switch cabinet 3 after the telescopic rod 52 extends out of the first power connection unit 51.

[0092] Vertical correction: Since the deviation caused by the wheel air pressure generally causes the center of gravity of the first power connection unit 51 to drop, a first position sensor 32 and a second position sensor 33 are provided on the hydrogen production control switch cabinet 3. After the telescopic rod 52 extends out of the first power connection unit 51, the L1-L3 three-phase terminals 53 contact the hydrogen production control switch cabinet 3 and then move vertically upward. After the L1-L3 three-phase terminals 53 contact the first position sensor 32, the movement of the telescopic rod 52 is stopped, and the vertical correction is in place.

[0093] Horizontal correction: Due to the distance or angle deviation between the wheels of the PEM hydrogen production equipment 4 and the baffle 8, the second position sensor 33 is set on the side close to the baffle 8. After the vertical correction is in place, the L1~L3 three-phase terminals 53 move horizontally toward the second position sensor 33. After the L1~L3 three-phase terminals 53 contact the second position sensor 33, the movement of the telescopic rod 52 is stopped, and the horizontal correction is in place.

[0094] After the angle correction, vertical direction correction, and horizontal direction correction are in place, the circuit breaker in the hydrogen production control switch cabinet 3 is controlled to close, enabling the power supply of the PEM hydrogen production device 4 to produce hydrogen.

[0095] There are multiple baffle 8 devices to position multiple rear wheels of the PEM hydrogen production device 4.

[0096] The aviation kerosene preparation center 9 schedules the in-vehicle PEM hydrogen production coupling devices in hydrogen production station a1, hydrogen production station b1, the first hydrogen production station a 1i , the second hydrogen production station b 1j and the third hydrogen production station c 1k The in-vehicle PEM hydrogen production coupling device transports the produced hydrogen along the road to the aviation kerosene preparation center 9 to synthesize aviation kerosene at the aviation kerosene preparation center 9. The method for preparing aviation kerosene by hydrogenating biomass raw materials includes the following steps:

[0122] Optionally, the telescopic rod 52 is covered with an insulating outer sheath to improve electrical safety.

[0123] Embodiment 5

[0124] The difference between this embodiment and the first embodiment is that Fig.12 A hydrogen production station a1 is set up at the farthest point on the north side of the aviation fuel preparation center 9. The wind resources are the most abundant at the hydrogen production station a1, so the wind power hydrogen production capacity is the largest.

[0125] A hydrogen production station a2 is set up at the farthest point on the south side of the aviation fuel preparation center 9. The solar energy resources are the most abundant at the hydrogen production station a2, so the photovoltaic hydrogen production capacity is the largest.

[0126] The average distance from all hydrogen production stations to the aviation fuel preparation center 9 is calculated and marked as Q. The hydrogen production station whose distance to the aviation fuel preparation center 9 is less than Q is marked as b. v , v is an integer greater than 1.

[0128] Step W1: The hydrogen production stations a1 and a2 count the remaining hydrogen S of the on-vehicle PEM hydrogen production coupling devices in the stations at a fixed time or a predetermined time on the same day. a1 and S a2 ; The fixed time can be, for example, 17:00, 18:00, 19:00, 20:00, or 21:00 every day; The hydrogen demand of the aviation kerosene preparation center 9 for the next day is denoted as P.

[0136] Embodiment 6

[0137] The difference between this embodiment and the first embodiment is that the first embodiment considers transporting hydrogen from the distributed hydrogen production station to the aviation kerosene preparation center, but the ratio of hydrogen and other gases when mixed is precisely controlled, and the on-board PEM hydrogen production coupling device controls the on-off of the gas cylinder pipeline by a valve. According to the ratio of hydrogen and other gases, the gas cylinder valve is sometimes opened, and sometimes reduced or closed, that is, the opening of the gas cylinder valve increases and decreases in a certain range. This feature requires the gas cylinder valve to be more accurately and reliably controlled to avoid the instability of the hydrogen ratio and thus affect the yield rate of aviation kerosene preparation. This embodiment controls the valve opening by a servo motor, thereby improving the valve control accuracy and reliability.

[0138] like Figure 13-15 As shown, the box body of the PEM hydrogen production device 7 of the vehicle-mounted PEM hydrogen production coupling device includes a fixed bracket 204, and each row of the fixed bracket 204 is fixedly provided with a plurality of gas cylinders 205. The upper end of each gas cylinder 205 is provided with a separate valve 202 which is connected in series in the gas distribution pipe and controls the opening and closing of the gas cylinder 205. The gas distribution pipes on each row of gas cylinders 205 are connected in parallel to the trunk pipe, and the trunk pipe is provided with a main gas valve 201 and a pressure gauge 203; a weight sensor 206 is provided at the bottom of the gas cylinder 205.

[0139] The opening degrees of the separate valve 202 and the main gas valve 201 are controlled by different servo motors, that is, the servo motor controls the opening and closing of the separate valve 202 and the main gas valve 201 .

[0140] Optionally, the separate valve 202 and the main gas valve 201 are controlled by servo motors with different current levels, and the different current levels result in different output driving forces of the servo motors. For example, the current level of the servo motor corresponding to the separate valve 202 is 0.5A, and the current level of the servo motor corresponding to the main gas valve 201 is 1.5A.

[0141] The servo motor includes a stator core 301, a rotor, a stator winding 302, an angle detection device, a housing 308, an end cover 310 and a bearing 309. The stator core 301 is arranged in the housing 308. The inner side of the stator core 301 of the stator is provided with four teeth arranged at equal angles along the circumferential direction. The stator winding 302 is wound around the four teeth respectively. The rotating shaft 306 of the rotor is assembled between the end cover 310 and the housing 308 through the bearing 309.

[0142] The rotor includes a rotating shaft 306, a yoke 305 and a permanent magnet 307. The rotating shaft 306 fixes the yoke 305 and the permanent magnet 307 and outputs driving force as the output axial discrete valve 202 and the main gas valve 201. The yoke 305 is made of soft magnetic material; the permanent magnet 307 is made of neodymium iron boron. Two adjacent permanent magnets 307 close to the Hall sensor 303 in the angle detection device provide induced magnetic flux for the Hall sensor 303, so that the Hall sensor 303 outputs a corresponding voltage signal, thereby determining the displacement of the rotor, thereby measuring the angular position of the servo motor in real time to control the rotation angle of the servo motor. The yoke 305 is sleeved and fixed on the rotating shaft 306. An even number of radially magnetized permanent magnets 307 are evenly distributed around the yoke 305. In this embodiment, the number of permanent magnets 307 is 4, and the polarities of the four permanent magnets 307 are staggered, that is, the four permanent magnets 307 are staggered along NSNS. Optionally, the four permanent magnets 307 are tile-shaped or arc-shaped and have equal thickness along the radial direction of the rotor, so as to reduce the change of the magnetic lines of force of the teeth during the movement of the rotor, thereby eliminating the torque fluctuation caused by the change of magnetic flux.

[0143] Optionally, a gap is provided between two adjacent permanent magnets 307 , and the gap is 0.5-0.8 of the air gap between the tooth shoe 312 and the permanent magnet 307 .

[0144] Changing the current polarity and amplitude of the stator winding 302 can adjust the direction and magnitude of the output torque of the servo motor. The Hall sensor 303 monitors the angular position in real time to achieve the function of accurately controlling the rotation angle of the servo motor.
