Description

Technical Field

[0001] This invention relates to the technical field of rapid preparation of natural gas hydrates, and in particular to a biomimetic tree-like hydrate promoting device. Background Technology

[0002] Natural gas hydrates possess strong gas storage capacity, mild storage conditions, and high safety. Compared with traditional natural gas storage and transportation methods, using natural gas hydrates as a carrier is more economical and safer, thus showing broad application prospects. However, the low water-to-hydrate conversion rate poses a challenge for commercial applications, and selecting a suitable method to promote hydrate formation is crucial for the success of this technology.

[0003] To achieve the industrial production of natural gas hydrates, various formation enhancement strategies, including physical methods, external field effects, and additive methods, have been explored. Among these, porous media have shown unique advantages as kinetic promoters. These media, through their high specific surface area and capillary action characteristics, significantly increase the gas-liquid contact area, thereby accelerating the mass and heat transfer processes between gas and liquid, and improving the hydrate formation rate and gas storage density. However, existing porous media such as activated carbon, nanoparticles, and silica gel have some limitations. While activated carbon and silica gel have high adsorption capacities, they are easily saturated during hydrate formation and are difficult to regenerate; although nanoparticles enhance mass transfer efficiency, their stability and difficulty in recycling limit practical applications. These drawbacks highlight the necessity of developing novel hydrate-promoting materials. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this invention are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or device.

[0028] The following will combine Figures 1-5 A detailed description of a biomimetic tree-like hydrate promoting device according to an embodiment of the present invention will be provided.

[0029] This invention provides a biomimetic tree-like hydrate promoting device that not only overcomes the shortcomings of existing kinetic promoting materials but also simulates the efficient water and gas exchange mechanism of trees in nature. It offers an innovative and efficient solution for the commercial utilization and storage of natural gas hydrates, representing a novel, environmentally friendly, cost-effective, and easily industrially applicable gas hydrate promoting material and its preparation method. Based on a biomimetic tree-like structure design, this device effectively accelerates hydrate formation and can be widely applied to the industrial production research of natural gas hydrates. Example

[0030] refer to Figures 1 to 5 As shown, the biomimetic tree-like hydrate promoting device provided in Embodiment 1 of the present invention is made of tree-like absorbent cardboard modified by soaking in sodium dodecyl sulfate. The biomimetic tree-like hydrate promoting device includes a trunk 1 and 10 branches 2 symmetrically distributed on both sides of the trunk 1 along the center line of the trunk 1. The width of the trunk 1 gradually decreases from bottom to top. The branches 2 are distributed at intervals from the bottom of the trunk upwards. That is, there are 5 branches symmetrically distributed on each side of the trunk 1. There is a certain distance between two adjacent branches 2 on the same side. The length of the branches 2 gradually decreases from bottom to top along the length direction of the trunk 1. The length of the branches 2 is the distance from the center of the edge of the trunk 1 to the center of the end of the branch. The width of the branches 2 first increases and then decreases in the direction away from the trunk 1.

[0031] refer to Figure 1 and Figure 2As shown, the main trunk 1 features a structure with a wide bottom and a pointed top, which better accommodates the growth of natural gas hydrates. Furthermore, the main trunk 1 has an upright structure with a bottom width of 27 mm and a semi-circular top. The bottom width of the main trunk 1 is 1.2 to 3 times the top width. This design effectively utilizes the growth of methane hydrates on the main trunk. The overall structure of the main trunk 1 resembles the trunk of a tree, mimicking the shape of natural trees to provide a larger surface area, allowing more gas and water molecules to contact the material surface. This structural design effectively increases the gas-liquid contact area, thereby accelerating the hydrate formation process, especially within a limited space, enabling more efficient gas conversion and rapid growth of methane hydrates.

[0032] refer to Figure 1 , Figure 2 and Figure 3 As shown, the biomimetic tree-like hydrate promoting device provided in Embodiment 1 of the present invention is made of tree-like absorbent paper modified by soaking in sodium dodecyl sulfate. The biomimetic tree-like absorbent paper is prepared using materials from natural sources, and its production and use process has a small impact on the environment, which meets the requirements of sustainable development. It not only reduces the burden on the environment, but also provides a green solution to promote the clean use of energy.

[0033] refer to Figures 1 to 3 As shown in Embodiment 1 of the present invention, a biomimetic tree-shaped hydrate promoting device is provided, wherein the length of the branch 2 located at the bottom of the trunk 1 is 1.5 to 2.5 times the length of the branch 2 located at the top of the trunk 1. This setting can better adapt to the biomimetic tree structure setting. The distribution structure of the branch 2 on the trunk 1 is similar to the distribution of leaves on the trunk. This setting helps to dissipate the heat generated during the methane hydrate reaction in a timely manner, avoid the temperature being too high and inhibiting the formation of hydrate, thereby maintaining the continuous progress of the reaction. Furthermore, the lengths of the branches along the length of the trunk from bottom to top are 22 mm, 21 mm, 15 mm, 13 mm, and 10 mm respectively. The distance between the center points of two adjacent branches at the edges of the trunk gradually increases along the length of the trunk from bottom to top. Specifically, the distance from the center point of the branch at the edge of the trunk to the bottom of the trunk is 22 mm, 40 mm, 59 mm, 81 mm, and 104 mm respectively along the length of the trunk. This structure incorporates the distribution pattern of leaves on a tree trunk, which can better improve the crystallization and growth of methane hydrate on the biomimetic tree-shaped hydrate promoting device. It can also better utilize this structure to improve the combination of water molecules and methane gas, thereby increasing the efficiency and rate of methane hydrate formation.

[0034] refer to Figures 1 to 5As shown in Embodiment 1 of the present invention, a biomimetic tree-like hydrate promoting device is provided. The branches are cut into three parts along their length, with the top of each branch being semi-circular. By cutting the branches into three parts along their length, the cut portions act as leaf ribs. Furthermore, cutting the branches into three parts increases the surface area in contact with the gas through the folded "leaves," allowing more liquid and gas to participate in the reaction simultaneously, thereby improving the efficiency and rate of hydrate formation. After cutting the branches into three parts along their length, each part acts as a folded leaf, enabling the biomimetic tree-like hydrate promoting material to unfold in three-dimensional space, making more effective use of the reactor space. This not only ensures that each part fully contacts the reactants but also helps control the uniformity of the reaction environment. Moreover, the folded branches can contact the gas from multiple angles, overcoming the potential for insufficient contact in certain directions with a single planar material.

[0035] This invention provides a biomimetic tree-like hydrate promoting device. The tree-like structure, with its numerous branches, provides a large surface area, allowing more gas and water molecules to come into contact. The precisely trimmed and segmented branches greatly enhance the interaction between gas and liquid, promoting hydrate formation. The longitudinal extension of the tree-like structure guides hydrate growth along a specific direction, fully utilizing the longitudinal space within the reactor, thereby optimizing the hydrate formation process and morphology. The distribution pattern of the branches on the trunk improves reaction efficiency; due to the more uniform distribution of water and gas and the increased contact area, the reaction rate and efficiency are significantly enhanced. This design reduces reaction time and increases the hydrate formation rate. Because hydrates can form uniformly and compactly along the biomimetic tree-like hydrate promoting device, it helps increase the storage density of the final methane hydrate product, making storage and transportation more efficient and economical.

[0036] refer to Figures 1 to 5As shown in Embodiment 1 of the present invention, a biomimetic tree-like hydrate promoting device is provided. The branches are cut into three equal-width sections along their length, and the main trunk is cut into two symmetrical sections along its length. The cutting line of the main trunk is two-thirds to three-quarters of its length and extends through the bottom of the main trunk. Cutting the main trunk into two symmetrical sections along its length allows for folding of the main trunk and increases its specific surface area. This, combined with the folded branches, further increases the surface area in contact with the gas, allowing more liquid and gas to participate in the reaction simultaneously, thereby improving the efficiency and rate of hydrate formation. After cutting the branches into three sections along their length, each section acts as a folded leaf, enabling the biomimetic tree-like hydrate promoting material to unfold in three-dimensional space. This more effectively utilizes the space of the reaction vessel, ensuring that each section fully contacts the reactants and helping to control the uniformity of the reaction environment. Furthermore, the folded branches can contact the gas from multiple angles, overcoming the potential for insufficient contact in certain directions with a single planar material.

[0037] The first embodiment of this invention provides a biomimetic dendritic hydrate promoting device, which is made of dendritic absorbent paper modified by soaking in sodium dodecyl sulfate. The specific surface area of ​​the sodium dodecyl sulfate-modified dendritic absorbent paper is 0.00496 m² / g. The sodium dodecyl sulfate-modified dendritic absorbent paper used in the biomimetic dendritic hydrate promoting device is prepared using the following method:

[0038] Immerse the dendritic absorbent cardboard in a sodium dodecyl sulfate solution with a concentration of 200 ppm to 500 ppm for 20 to 40 minutes at a temperature of 15 to 25 degrees Celsius.

[0039] After soaking, the dendritic absorbent cardboard is dried at 80-120 degrees Celsius for 50-70 minutes to obtain dendritic absorbent cardboard modified by sodium dodecyl sulfate soaking.

[0040] Specifically, the concentration of sodium dodecyl sulfate solution used to soak the dendritic absorbent paper was 300 ppm, the soaking time was 30 minutes, and the soaking temperature was 20°C. After soaking, the dendritic absorbent paper was dried at 100°C for 60 minutes. SDS solution (sodium dodecyl sulfate solution) is a highly efficient surfactant whose core function is to effectively reduce the tension at the gas-liquid interface. Sodium dodecyl sulfate soaking in the modified dendritic absorbent paper increases the contact area between the gas and liquid, as well as the solubility of the gas in the liquid, which is crucial for the formation of methane hydrate. After soaking in sodium dodecyl sulfate, the surface and internal properties of the dendritic absorbent paper are altered. This process allows the gas to dissolve and disperse effectively not only on the outer surface of the dendritic material but also within its internal microstructure, improving gas utilization and reaction efficiency. The use of sodium dodecyl sulfate (SDS) impregnation-modified dendritic absorbent paper results in a large surface area. During impregnation, this larger surface area provides more contact points, allowing SDS to more fully cover and act on the material surface. Extensive SDS surface coverage enhances the efficiency and uniformity of subsequent reactions. The biomimetic dendritic hydrate promoter made from this SDS-modified dendritic absorbent paper, due to its unique structure and material properties, can adapt to different reaction environments and conditions, including variations in pressure and temperature. Its wide applicability makes it an ideal promoter choice for various hydrate production systems. By improving hydrate formation efficiency and reducing required reaction time, the biomimetic dendritic absorbent paper can significantly reduce energy and operating costs in industrial production processes. Furthermore, the relatively low manufacturing cost of the biomimetic dendritic hydrate promoter further enhances the economic benefits of methane hydrate production.

[0041] This invention provides a biomimetic tree-like hydrate promoting device using tree-shaped absorbent paper modified with sodium dodecyl sulfate. The device includes a main trunk and 10 branches symmetrically distributed on both sides of the trunk's centerline. The width of the main trunk gradually decreases from bottom to top. The branches are spaced apart along the bottom of the main trunk, and their lengths gradually decrease from bottom to top along the length of the main trunk. The length of a branch is the distance from the center of the branch's edge to the center of its end. The width of the branches first increases and then decreases in the direction away from the main trunk. By mimicking the shape of natural trees, this device provides a large surface area, allowing more gas and water molecules to contact the surface of the promoting material. This structural design effectively increases the gas-liquid contact area, thereby accelerating the hydrate formation process. Especially within a limited space, it enables more efficient gas conversion and rapid growth of methane hydrates. This not only overcomes the shortcomings of existing kinetic promoting materials but also simulates the efficient water and gas exchange mechanism of trees in nature, providing an innovative and efficient solution for the commercial utilization and storage of natural gas hydrates. Example

[0042] Based on the same inventive concept, and referring to Figures 1 to 5 As shown, the biomimetic tree-like hydrate promoting device provided in Embodiment 2 of the present invention is made of tree-like absorbent cardboard modified by soaking in sodium dodecyl sulfate. The biomimetic tree-like hydrate promoting device includes a trunk 1 and 10 branches 2 symmetrically distributed on both sides of the trunk 1 along the center line of the trunk 1. The width of the trunk 1 gradually decreases from bottom to top. The branches 2 are distributed at intervals from the bottom of the trunk upwards. That is, there are 5 branches symmetrically distributed on each side of the trunk 1. There is a certain distance between two adjacent branches 2 on the same side. The length of the branches 2 gradually decreases from bottom to top along the length direction of the trunk 1. The length of the branches 2 is the distance from the center of the edge of the trunk 1 to the center of the end of the branch. The width of the branches 2 first increases and then decreases in the direction away from the trunk 1.

[0043] like Figure 1As shown, the base width of the main trunk 1 is set at 27 mm, gradually tapering towards the tip as the height increases. Ten branches 2 extend evenly from the sides of the main trunk, symmetrically distributed on both sides, with each branch ending in a semi-circular shape. The lengths of the branches from the center of the main trunk edge to the center of the branch end, from bottom to top, are 22 mm, 21 mm, 15 mm, 13 mm, and 10 mm respectively. The heights of the branches 2 from the center of the main trunk edge to the bottom are 22 mm, 40 mm, 59 mm, 82 mm, and 105 mm respectively. Each branch is divided into three equal-width sections during cutting, which can be done using a laser cutter. The resulting tree-shaped absorbent cardstock is completely immersed in a 300 ppm sodium dodecyl sulfate (SDS) solution. The immersion process is carried out at room temperature (approximately 20°C) for 30 minutes to ensure that the SDS molecules are fully adsorbed onto the cardstock fibers. After soaking, the cardboard is gently squeezed to remove excess solution from the surface, and then transferred to a drying oven and dried at a constant temperature of 100°C for 60 minutes to obtain a biomimetic dendritic gas hydrate promoting device.

[0044] The surface micromorphology of the biomimetic dendritic hydrate promoting device of this embodiment was observed using SEM. The observation results are as follows: Figure 3 As shown in the figure. The surface pore size distribution of the SEM image was obtained after grayscale processing, and the results are as follows. Figure 4 As shown in the figure, it can be seen that after the dendritic absorbent paper is soaked and modified with sodium dodecyl sulfate (SDS), the surface and internal properties of the material are changed. The SDS-modified dendritic absorbent paper allows gas to dissolve and disperse effectively not only on the outer surface of the dendritic material but also within its internal microstructure, improving gas utilization and reaction efficiency. The SDS-modified dendritic absorbent paper also provides a larger surface area, which provides more contact points during soaking, allowing SDS to more fully cover and act on the material surface. Extensive SDS surface coverage helps enhance the efficiency and uniformity of subsequent reactions. The biomimetic dendritic hydrate promoting device made with SDS-modified dendritic absorbent paper, due to its unique structure and material properties, can adapt to different reaction environments and conditions, including changes in pressure and temperature. Its wide applicability makes it an ideal promoting device choice for various hydrate production systems. By improving hydrate formation efficiency and reducing required reaction time, biomimetic dendritic absorbent paper can significantly reduce energy and operating costs in industrial production processes. Furthermore, the relatively low manufacturing cost of the biomimetic dendritic hydrate promoting device further enhances the economic benefits of methane hydrate formation.

[0045] A hydrate formation experiment was conducted using the biomimetic dendritic hydrate promoting device of this invention. The equipment used in the hydrate formation experiment was a 120 ml capacity reactor, with methane selected as the reaction gas. Before the experiment, the reactor body was first removed and thoroughly cleaned with deionized water, including the interior, base, and lid, at least three times to remove any possible impurities. The cleaned reactor was then thoroughly dried in a drying oven. After drying, the reactor body was placed back on its base, and 30 g of deionized water was added to the reactor. The biomimetic dendritic hydrate promoting device of this invention was then placed inside the reactor. Afterward, sealing gaskets were installed and screws tightened. All relevant equipment was checked to ensure normal operation. The gas cylinder was then closed, all valves were opened, and the vacuum pump was started to perform a vacuuming operation. The vacuum level was monitored using a pressure sensor, and the airtightness of the device was ensured until the pressure change was less than 0.01 MPa for 10 consecutive minutes. Then, the vacuum pump was turned off. Next, the gas cylinder was opened, and a small amount of methane gas was injected into the reactor. Excess gas was discharged through the exhaust valve. This operation was repeated 2 to 3 times. The high and low temperature alternating test chamber was started for cooling, and the data acquisition system was activated to record data. When the liquid phase temperature inside the reactor stabilized at 274.15 K, the methane inlet valve was quickly opened to pressurize until the pressure reached 6.5 MPa, after which the gas cylinder and inlet valve were closed. Throughout the experiment, the temperature of the refrigeration system was kept constant, and the changes in gas phase temperature, liquid phase temperature, and gas phase pressure inside the reactor were recorded. The experimental results showed that, under the action of the biomimetic dendritic hydrate formation promoting material, hydrate nuclei began to form after 10 seconds, and the reaction ended after 220 minutes. The final methane gas consumption was 0.17 mol, and the time required for the gas consumption to reach 90% of the total gas consumption during the methane hydrate formation process was 100 minutes. The biomimetic dendritic hydrate promoting device after the reaction is as follows: Figure 5 As shown

[0046] To compare the effectiveness of the biomimetic dendritic hydrate formation promoting material, a controlled experiment was conducted without adding any promoting device. Keeping all other experimental conditions identical, it was observed that without using the biomimetic dendritic hydrate promoting device of this embodiment, hydrate nuclei appeared at the gas-liquid interface 56 minutes after the start of the experiment, and the final methane gas consumption was 0.013 mol, indicating that hydrate formation was significantly delayed and the amount produced was extremely small without the promoter.

[0047] Compared to the control experiment, the biomimetic tree-like hydrate-promoting device used in this embodiment significantly shortened the induction period and total reaction time for hydrate formation. Furthermore, the biomimetic tree-like hydrate-promoting device of this embodiment also significantly improved the hydrate formation rate and the final gas consumption, thus verifying its high efficiency in accelerating natural gas hydrate formation.

[0048] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations to the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
