preparation example Construction

[0033] The embodiment of the present invention also provides a method for preparing an aluminum alloy for hydrogen production by hydrolysis, comprising the following steps:

[0034] (1) take raw materials by mass percentage;

[0035] (2) Weigh the raw materials and balls in proportion, and then charge them under the protection of an inert gas. Place the filled ball mill jar symmetrically on the turntable of the planetary ball mill and fix it. Take it out under protection to obtain the aluminum alloy for hydrogen production by hydrolysis.

[0036] In the present invention, the hydrolysis of hydrogen-producing aluminum alloy is carried out under the protection of inert gas during the whole preparation process; in some preferred embodiments of the present invention, the hydrolysis of hydrogen-producing aluminum alloy is carried out under the protection of argon gas during the whole preparation process. The invention adopts an atmosphere protection method to avoid oxidation of al...

Embodiment 1

[0046]Example 1 of the present invention provides a hydrolysis aluminum alloy for hydrogen production, which is composed of the following raw materials in mass percentage: Al, 94wt%; K, 2wt% and Bi 2 o 3 , 4wt%. .

[0047] The aluminum alloy for hydrogen production by hydrolysis is prepared by the following method:

[0048] (1) take each raw material by mass percentage;

[0049] (2) Weigh the raw materials and grinding balls according to the ball-to-material ratio of 10:1, and then charge them in an argon-protected environment. Fill the grinding balls and raw materials according to 3 / 4 of the volume of the ball mill tank. The ball mill jar is symmetrically placed on the turntable of the planetary ball mill and fixed, and then ball milled at 200r / min for 0.5 hours;

[0050] (3) The ball-milled mixed material is taken out under the protection of argon to obtain the hydrolyzed hydrogen-producing aluminum alloy.

Embodiment 2

[0052] Prepare the aluminum alloy according to the method of Example 1, the difference is that the raw materials are: Al, 93wt%; Zn, 4wt% and SnCl 2 , 3wt%.

Abstract

The invention discloses a hydrolysis hydrogen production aluminum alloy. The hydrolysis hydrogen production aluminum alloy comprises raw materials including, by mass percent, 90 to 95% of Al and 5 to10% of an additive. The additive is one or multiple of a metal element, metallic oxide and metal chloride, the metal element comprises one or multiple of magnesium, antimony, zinc, lead, cadmium, bismuth, tin, potassium and sodium, the metallic oxide comprises one or multiple of magnesium oxide, antimony oxide, zinc oxide, lead oxide, cadmium oxide, bismuth oxide, tin oxide, potassium oxide and sodium oxide, and the metal chloride comprises one or multiple of magnesium chloride, antimony chloride, zinc chloride, lead chloride, cadmium chloride, bismuth chloride, tin chloride, potassium chloride and sodium chloride. In the hydrolysis hydrogen production aluminum alloy, the cost of hydrolysis hydrogen production aluminum alloy is greatly reduced while hydrogen production is ensured. The invention further provides a preparing method of the hydrolysis hydrogen production aluminum alloy and application.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a hydrolyzed hydrogen-producing aluminum alloy and a preparation method and application thereof. Background technique [0002] Energy is not only the basis and important guarantee for the survival and continuous development of human society, but also the focus of political, economic and diplomatic attention of all countries in the world. Throughout history, every progress in human society has been accompanied by changes in energy sources. At present, the world's energy composition is still dominated by the three traditional energy sources of coal, oil and natural gas. Nowadays, my country's economic development has entered a new normal, and the growth rate of energy consumption has slowed down. However, the quality and efficiency of development are prominent, and supply-side structural reforms are urgent. [0003] Hydrogen is the No. 1 element in the periodi...
