Description

Technical Field

[0001] This invention relates to the field of electrochemical process technology, and in particular to an electrochemical treatment method and apparatus. Background Technology

[0002] Exploring the intrinsic structural changes of matter and studying the aging process of matter over time has always been a pure fundamental scientific pursuit for scientists. First, the "aging" discussed here is not the commonly understood concept of "protein biomolecule aging" or "material degradation aging." The conventional concept of "aging" refers to the "denaturation" of biomolecules or the degradation of materials, which includes chemical or physical processes that can be explained by existing theories, such as the collapse of higher-level physical structures or the breaking of chemical bonds. This invention proposes a method for molecular aging, or rather, altering the inherent physicochemical properties of molecules, which differs from previous concepts. It can be understood that, regardless of size, such as a water molecule, even after being subjected to some drastic treatment or undergoing some special treatment, its structure remains that of ordinary water. That is, superficially, it still consists of one oxygen atom and two hydrogen atoms connected by two hydrogen-oxygen bonds, and its characteristic spectroscopic properties (peak positions) such as infrared spectroscopy do not show significant changes; conventional characterization still shows it as "water." However, certain "properties" have undergone definite (reproducible) changes, changes that have not been previously considered. To put it figuratively, just as a person ages over time, a pair of shoes or a piece of clothing ages with wear, and anything ages over time, a water molecule, after being repeatedly "used, processed," or "bombarded," should also age. The "aged" water molecule is not fundamentally different from the original molecule; based on current tools, the molecular structure detected is still H2O. Just like a new pair of shoes that has worn out is still the same pair of shoes—as long as it hasn't disintegrated, it's still the same item, just "old" or "aged." However, it's clear that something "old" or "aged" still has some discernible differences from the original new thing. For water molecules, once a definite and significant change in a certain property is detected after processing, these changes may bring entirely new functions and values, equivalent to obtaining a "new" functional material, making the classification of substances more refined and diverse.

[0095] To further illustrate the present invention, the following detailed description of an electrochemical treatment method and apparatus provided by the present invention is provided in conjunction with embodiments, but it should not be construed as limiting the scope of protection of the present invention.

[0096] Example 1

[0097] use Figure 1 The electrochemical treatment device shown uses pure water as the substance to be treated for electrochemical treatment. The size of the conductive plate is 10cm×5cm×0.5cm; the number of layers in the multilayer conductive plate is 5.

[0098] The methods include:

[0099] Five layers of conductive plates (copper plates) are bonded together and clamped together using the first and second clamps. The gap between adjacent conductive plates is less than 0.1 mm. The anode wire is connected to the negative terminal of the power supply, and the cathode wire is connected to the positive terminal of the power supply. A 10V DC voltage is applied, and the current display shows 20A. The samples are treated for 30 days and 60 days. Water in the feed tank slowly passes through the gaps between the copper plates by gravity and accumulates in the sample collection tank.

[0100] The collected water samples were subjected to hydrogen evolution activity tests, with pure water that had not undergone the aforementioned electrochemical treatment used as a comparison. The test conditions were: Pt / C catalyst, three-electrode system, rotating disk, and electrolytes of the treated water from Example 1 (both electrolyzed and untreated), prepared with 1 mol / L KOH electrolyte containing 99.99% pure KOH. Water sample 1 (electrolyzed for 60 days), water sample 3 (electrolyzed for 30 days), deionized water sample 2 (taken on the day of test for water sample 1), and deionized water sample 4 (taken on the day of test for water sample 3).

[0101] Experimental results are as follows Figure 3 As shown. Figure 3 The results show the hydrogen evolution test results of the water sample treated in Example 1 of this invention. The experimental results indicate that, under the same test conditions, the water treated with the above-mentioned electrolysis exhibits better stability under alkaline conditions. Figure 3 As can be seen, under the same test conditions, water treated with electricity showed worse hydrogen evolution performance than water without electricity, meaning that water was less likely to ionize and exhibited more stable performance.

[0102] Example 2

[0103] use Figure 1 The electrochemical treatment device shown uses hydrogen as the substance to be treated for electrochemical treatment. The size of the conductive plate is 15cm×5cm×1cm; the number of layers in the multilayer conductive plate is 5.

[0104] The methods include:

[0105] Five layers of conductive plates (copper plates) are bonded together and clamped together using the first and second clamps. The gap between adjacent conductive plates is less than 0.1 mm. The anode wire is connected to the negative terminal of the power supply, and the cathode wire is connected to the positive terminal of the power supply. A 10V DC voltage is applied, and the current display shows 21A. The power supply is applied for 50 days. Hydrogen gas in the feed gas bag slowly passes through the gap between the copper plates and accumulates in the sample collection gas bag.

[0106] Gas chromatography was performed on the collected hydrogen samples, and it was found that the peak position of the hydrogen samples had shifted slightly. The electrochemical hydrogenation performance of the hydrogen was characterized, and compared with hydrogen that had not undergone the above electrochemical process, it was found that the stability of the treated hydrogen was better.

[0107] Example 3

[0108] use Figure 2The electrochemical treatment device shown uses methanol as the substance to be treated and copper powder as the conductive powder. Both the first and second conductive plates are copper sheets with dimensions of 10cm × 6cm × 0.8cm; the distance between the first and second conductive plates is 5cm; both the first and second conductive plates penetrate the sealing device (sealing cap) and enter the conductive powder in the sample cup.

[0109] The methods include:

[0110] Copper powder was placed in a 200mL sample cup, filling it to half its volume. Then, 100mL of methanol was added, allowing the methanol to enter the gaps between the conductive powder particles. The cup was then sealed with a cap. The first wire was connected to the first conductive plate, and the second wire was connected to the second conductive plate. Both the first and second wires were connected to a power source. A 1V DC voltage was applied, and the current display showed 50A. The samples were then subjected to power-on treatment for 30 days and 70 days.

[0111] The electro-oxidation performance of the treated methanol was tested using a commercially available PtRu / C catalyst. The test results are as follows: Figure 4 As shown. Figure 4 The results show the electro-oxidation performance test results of methanol after treatment in Example 3 of this invention; where N represents untreated methanol, E1 represents methanol treated with electricity for 30 days, and E2 represents methanol treated with electricity for 70 days. Figure 4 As can be seen, the stability of methanol improves after electrolysis. Figure 4 As can be seen, under the same test conditions, methanol treated with electricity has a worse electro-oxidation performance than methanol without electricity, meaning that methanol is less likely to undergo oxidation and exhibits more stable performance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
