Embodiment Construction

[0026] Specific embodiments of the present invention will now be described below.

[0027] Such as figure 1 Shown are the micron and nanometer size pure aluminum powder (Al) and commercial aluminum hydroxide (Al(OH) 3 ) Scanning electron microscope (SEM) photo of the powder, the shape of the aluminum particles is irregular, and the size has a certain distribution.

[0028] A method for preparing high-activity aluminum hydroxide suspension and reacting with pure aluminum powder to produce hydrogen has the following process and steps: 3 methods are used to prepare aluminum hydroxide (Al(OH) 3 ) Suspension: (1) Take a certain amount of micron or nano-sized aluminum (Al) powder and add it to a beaker containing a certain amount of water and mix it evenly, then place the beaker into an ultrasonic bath containing a certain amount of 40oC warm water After ultrasonic treatment for 1 hour, the aluminum powder reacts with water under ultrasonic conditions. After the reaction, aluminum hydroxi...

Abstract

The invention discloses a method for preparing a high-activity aluminum hydroxide suspension liquid and producing hydrogen through high-activity aluminum hydroxide suspension liquid and pure aluminum powder reaction. The method comprises the steps of adding a certain quantity of micro / nano-scale aluminum powder into a beaker filled with a certain quantity of water, uniformly mixing, then, placing the beaker into an ultrasonic water bath filled with a certain quantity of 40-DEG C warm water to carry out ultrasonic treatment for 1h, enabling aluminum powder to be reacted with water under an ultrasonic condition to obtain an aluminum hydroxide suspension liquid with high activity; placing 250ml of aluminum hydroxide suspension liquid with a certain concentration into a glass vessel with a known volume, next, adding a certain quantity of micro-scale metal aluminum powder, uniformly stirring the aluminum powder and the suspension liquid by using a glass rod, and then, sealing the glass vessel; enabling pure aluminum powder to be continuously reacted with water in the aluminum hydroxide suspension liquid under the conditions of normal temperature and normal pressure or normal temperature and vacuum to generate hydrogen. The method is mainly used for providing hydrogen sources for mobile kilowatt-level fuel cells and other medium-small portable fuel cells.

Description

Technical field [0001] The invention relates to a method for preparing a highly active aluminum hydroxide suspension and reacting with pure aluminum powder to produce hydrogen, and belongs to the technical field of chemistry and chemical engineering. Background technique [0002] Energy is the basis for human survival and development. With the development of society and population growth, people's demand for energy is increasing. The current energy supply is mainly based on fossil energy. The large-scale use of fossil energy faces limited resources and serious environmental problems, such as global warming, acid rain, increased haze weather, and excessive PM2.5. These factors make efficient and clean energy. The research and development of technology is imminent. Hydrogen energy has the advantages of a wide range of sources, zero emissions, and can be converted into other forms of energy. It is regarded as the most potential clean energy in the 21st century. The fuel cell is a...
