example 1

[0010] Example 1 Obtain 50g of aluminum powder with a particle size of 200--400 mesh in an inert atmosphere by a ball mill, stir and add it to 15g of gallium solution, eutectic (dissolve), gradually cool to achieve microcrystalline phase blending, and obtain 65g of alloy body. In the Kipp generator, the alloy body reacts with 30°C water to produce hydrogen gas. The reaction amount of metered gas converted to aluminum was 98.7.

example 2

[0011] Example 2 Stir 10 g of gallium solution into 50 g of aluminum powder with a particle size of 50-100 mesh in an inert atmosphere, completely cover the aluminum powder with gallium solution, and cool to form 60 g of alloy body. In the Kipp generator, the alloy body reacts with 30°C water to produce hydrogen gas. The reaction amount of metered gas converted to aluminum was 96.7.

example 3

[0012] Example 3 In an inert atmosphere, 50 g of aluminum powder with a particle size of 100--200 mesh was sintered with an oxyhydrogen flame, and 10 g of gallium solution was covered on the surface of the formed aluminum powder block to completely cover it, and then cooled to obtain a solid alloy. In the Kipp generator, the alloy body reacts with the aqueous solution to generate hydrogen gas. The aqueous solution contains an aluminum ion chelating agent with a concentration of 20% (molar percentage), and the chelating agent is deferoxamine methanesulfonate or malic acid. The reaction amount of metered gas converted to aluminum was 97.8.

Abstract

The invention relates to a method for manufacturing aluminum alloy. The aluminum alloy which can produce hydrogen is manufactured by a powder metallurgy process, and the aluminum alloy is stable in air and can produce the hydrogen when encountering water. The main component of the aluminum alloy is aluminum metal, the secondary component of the aluminum alloy is gallium metal, and the aluminum metal can totally react to produce the hydrogen.

Description

technical field [0001] The invention relates to an aluminum alloy which reacts with water to generate hydrogen by using aluminum gallium metal through powder metallurgy technology. The reaction of the aluminum alloy with water can produce hydrogen efficiently, rapidly and completely, which can be used in hydrogen-burning engine vehicles or hydrogen fuel cell vehicles, and can also supply hydrogen to emergency portable generators to drive wheelchairs, golf carts, Small agricultural machinery, battlefield robots, etc. can also provide hydrogen sources for hydrogen-burning engines in confined spaces (such as submarines) to maintain the health of the environment. In short, special aluminum alloys that can generate hydrogen as long as water is injected have broad application prospects and are the future Necessary products for social life. technical background [0002] With the depletion of oil and coal resources and rising prices, urban environmental governance requirements, env...
