Description
Technical Field
The invention belongs to the technical field of hydrogen production, and particularly relates to hydrogen production particles capable of generating a porous structure on site, and a preparation method and application thereof.
Background
Hydrogen has no toxic hazard and side effect on human body, is praised as the most effective and most ideal antioxidant and is widely applied. In recent years, a plurality of scholars research the biological effect of hydrogen and find that the hydrogen has an important health-care effect on human bodies. After entering human body, the hydrogen can permeate into the whole body rapidly, penetrate cell membrane, take away malignant active oxygen, and synthesize water to be discharged out of the body. At the same time, hydrogen also restores the cells that have been destroyed and oxidized.
Hydrogen-rich water, as the name implies, refers to water that contains abundant molecular hydrogen. The hydrogen-rich water is different from common water in that it has reducing power, can eliminate excess active oxygen in human body, purify blood, promote metabolism, prevent various diseases and is beneficial to human health. Currently, there are probably three following methods for the preparation of hydrogen-rich water: the first method is that hydrogen is directly dissolved in water through high-pressure equipment to form saturated hydrogen-rich water, but the cost of the high-pressure equipment is high, and the storage stability of the prepared hydrogen-rich water is poor; the second method is to dissolve hydrogen generated by electrolyzing water into water by an electrochemical method, but the type of products sold in the market at present are mixed, and simultaneously, the prepared hydrogen-rich water has lower concentration. The third is to put the hydrogen-producing particles into water and prepare hydrogen-rich water by utilizing a micro-electrolysis technology, however, the existing hydrogen-producing particles in the market cannot release hydrogen rapidly in order to ensure that the hydrogen-releasing effect is stable for a long time, so that the concentration of the hydrogen-rich water is difficult to improve and the health-care effect on human bodies is exerted.
Therefore, hydrogen production particles which can be conveniently and safely used and can rapidly release hydrogen are expected. When the hydrogen production particles are placed in a sealed water cup with a certain volume, not only can super-saturated hydrogen-rich water be obtained in a short time, but also natural mineral elements can be enriched in the water, and the health care effect on human bodies is exerted.
The present invention has been made to solve the above problems.

Wherein, the kaolin can be used as a main component of the sintered ceramic; the bentonite can be used as a binder; the medical stone contains various mineral elements beneficial to the growth and development of a human body, can be dissolved out of various trace elements and rare earth elements after being soaked in water, and has good adsorption effect; the zeolite has natural micropore structure, and can increase the specific surface area of the hydrogen producing particles, so that the hydrogen producing particles have more micropore structures. The addition of the silicon oxide can reduce the sintering temperature of the hydrogen production particles, and save more energy; cerium oxide has excellent antibacterial properties; taurine is not easily decomposed at high temperature, and appropriate acidity helps to neutralize alkaline substances generated after hydride hydrolyzes and releases hydrogen.
The second aspect of the present invention provides a method for producing the hydrogen-producing particles, comprising:
(1) ball milling and mixing
Ball-milling the hydrogen release material and the auxiliary agent for 2-5h respectively until the particle size of the powder is less than 50 μm, pouring the ball-milled hydrogen release material and auxiliary agent into a mixing pot, and mixing for 15-30min to ensure that the components are uniformly mixed.
(2) Punch forming
And (2) pouring the mixed powder obtained in the step (1) into a punch press for punch forming.
(3) Calcination screening
And (3) calcining the product formed in the step (2) in a 200-500 ℃ tube furnace under an inert atmosphere for 0.5-5h, and screening to obtain the hydrogen production particles.
Preferably, the calcination temperature is 300 ℃ and the calcination time is 1 h.
Preferably, the hydrogen-producing particles may be spherical, flaky, or columnar.
Such as nitrogen, argon, and the like.
After being prepared, the hydrogen production particles can be wrapped in a breathable and water-permeable packaging bag, then are sterilized by ultraviolet rays and are stored in a dry, cool and ventilated place.
A third aspect of the invention relates to the use of the hydrogen-producing particles of the first aspect for the preparation of hydrogen-enriched water for drinking or for contact with water in the food preservation, cultivation and growing industries for the production of hydrogen.
The invention has the following beneficial effects:
(1) compared with the traditional hydrogen production particles only added with metal powder, the hydrogen production particles of the invention are also added with a certain amount of hydride, such as calcium hydride or magnesium hydride, and can be rapidly decomposed in water to release hydrogen, and simultaneously, a porous ceramic structure can be further formed on site, so that the contact area between the hydrogen production particles and water is greatly increased, the metal powder is further promoted to form a galvanic cell effect, the metal powder in the hydrogen production particles reacts more thoroughly, and the hydrogen evolution speed of the hydrogen production particles is greatly improved. For example, 1 part of hydrogen-producing particles is added to 100 parts of water in a mass ratio and placed in a sealed container, and after 15 minutes, the hydrogen molecule content in the hydrogen-rich water can reach up to 800 ppb.
(2) The hydrogen production particles are added with natural minerals to ensure that the hydrogen-rich water is rich in trace elements such as magnesium, zinc, calcium and the like while decomposing and releasing hydrogen, thus being beneficial to improving the drinking water quality of human bodies and playing the health care role on the human bodies.

Detailed Description
The present invention will be further described with reference to the following embodiments.
Example 1
(1) Ball milling and mixing
Preparing 2g of magnesium powder and 1g of calcium hydride as hydrogen release materials; 5g of kaolin, 1g of bentonite, 1g of medical stone, 1g of zeolite, 0.5g of silicon oxide, 0.05g of cerium oxide and 0.5g of taurine are prepared as auxiliaries.
Grinding auxiliary agents such as kaolin, bentonite, medical stone, zeolite, silicon oxide, cerium oxide and taurine for 2-5h until the particle size of the powder is smaller than 50 mu m, simultaneously ball-grinding the hydrogen release material for 2-5h until the particle size of the powder is smaller than 50 mu m, pouring the ball-ground hydrogen release material and the auxiliary agents into a mixing pot, and mixing for 15-30min to ensure that all the components are uniformly mixed.
(2) Punch forming
And (2) pouring the mixed powder obtained in the step (1) into a punch press for punch forming.
(3) Calcination screening
And (3) calcining the product formed in the step (2) in a tubular furnace at 300 ℃ for 1 hour, and screening to obtain the hydrogen production particles.
Specific data: in a closed container, 2g of hydrogen production particles are placed in 200ml of water, and the concentration of hydrogen in the prepared water is detected by a snail hydrogen pen, as shown in figure 1, the concentration of hydrogen in the solution can reach 800ppb after 15 min.
Example 2
The difference from example 1 was only that 2g of magnesium powder, 0.5g of calcium hydride as a hydrogen-releasing material were prepared in step (1).
Specific data: in a closed container, 2g of hydrogen production particles are placed in 200ml of water, and the concentration of hydrogen in the prepared water is detected by a snail hydrogen pen, as shown in fig. 2, the concentration of hydrogen in the solution can reach 600ppb after 15 min. Compared with the embodiment 1, the hydrogen concentration is reduced because the adding amount of calcium hydride is reduced by half, so that the porous structure generated on site by hydrogen production particles is not enough, a part of magnesium powder is not fully contacted and reacted with water. Meanwhile, calcium hydride reacts with water rapidly, releases hydrogen rapidly in a short time and is discharged from water, and the released hydrogen has low solubility in water. The amount of calcium hydride is therefore reduced, resulting in a reduction in the amount of hydrogen produced by its reaction with water, resulting in a reduction in the hydrogen concentration in the final aqueous solution, which is a negligible factor.
Comparative example 1
The difference from example 1 is that in step (1), 2g of magnesium powder was prepared as a hydrogen-releasing material without adding calcium hydride or other hydride.
Specific data: in a closed container, 2g of hydrogen production particles are placed in 200ml of water, and the concentration of hydrogen in the prepared water is detected by a snail hydrogen pen, as shown in fig. 3, the concentration of hydrogen in the solution can only reach 100ppb after 30 min. It can be seen that if calcium hydride is not added, most of the magnesium powder can not directly contact with water and completely react due to the fact that a porous structure cannot be generated in situ in the contact process of the magnesium powder and the water, the released hydrogen amount is very low, and further the hydrogen concentration in the water is very low.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
