Embodiment 1

[0021] Accurately weigh 20 parts of flaky aluminum powder with a particle size of 20 μm, add 0.5 part of silica sol and 0.1 part of alcohol to make a uniform liquid, stir in a mixer for 5 minutes; manually mold into a block; move it into a vacuum drying oven Inside, the vacuum degree was kept at 133 Pa, and the temperature was 95° C., and dried for 20 minutes to make a non-loose solid composition.

[0022] Put 100g of this solid composition into an Erlenmeyer flask filled with 300g of 2%wt sodium hydroxide solution. When the temperature is 20~30°C, hydrogen bubbles will continuously escape from the surface of the solid composition. After about 30min The escape of hydrogen bubbles gradually weakened; heating the Erlenmeyer flask, when the temperature was 55~65°C, a large number of hydrogen bubbles continuously escaped from the surface of the solid composition, and the hydrogen bubbles gradually weakened after about 40 minutes; cooling the Erlenmeyer flask to 20~30 Under the con...

Embodiment 2

[0024] Accurately weigh 2 parts of flaky aluminum powder with a particle size of 50 μm, add 3 parts of silica sol and 0.01 part of alcohol to make a uniform liquid, stir in a mixer for 5 minutes; manually mold into a block; transfer to vacuum drying In the box, the vacuum degree was kept at 133 Pa, and the temperature was 100° C., and dried for 20 minutes to make a hard block solid composition.

[0025] Put 100g of this solid composition into an Erlenmeyer flask filled with 300g of 2%wt sodium hydroxide solution. When the temperature is 20-30°C, it can be seen that hydrogen bubbles are continuously escaping from the surface of the solid composition for about 30 minutes. Afterwards, the hydrogen bubbles escaped and gradually disappeared; when the Erlenmeyer flask was heated, when the temperature was 55-65°C, it could be seen that there were continuous hydrogen bubbles on the surface of the solid composition, and the hydrogen bubbles gradually disappeared after about 40 minutes; ...

Embodiment 3

[0027] Accurately weigh 15 parts of flaky aluminum powder with a particle size of 30 μm, add 3 parts of silica sol and 0.1 part of alcohol to make a uniform liquid, stir and knead in a mixer for 5 minutes, and then add 1 part of table salt with a particle size of 300 μm, Continue kneading for 5 minutes; manually mold into blocks; move into a vacuum drying oven, keep the vacuum at 133Pa, and dry for 20 minutes at a temperature of 100°C to make a slightly hard block solid composition with a certain shape.

[0028] This solid composition of 100g is put into the Erlenmeyer flask that the sodium hydroxide solution of 300g 2%wt is housed, when temperature is under the condition of 20~30 ℃, it can be seen that the surface of the solid composition is continuously and uniformly escaping hydrogen bubbles, After about 30 minutes, the hydrogen bubble escape rate remained unchanged; when the Erlenmeyer flask was heated, when the temperature was 55-65°C, it could be seen that intense continu...

Abstract

The invention relates to a solid mixture used for producing hydrogen by using aluminum powder. The mixture is characterized in that the mixture is composed of aluminum powder, edible salt, and silica sol. The mixture comprises, by mass, 2-20 parts of aluminum powder, 0-1 part of edible salt, 0.5-3 parts of silica sol, and 0.01-0.1 parts of alcohol. With the adhesion of silica sol, aluminum powder and edible salt particles are kneaded into a certain solid shape, such that chemical reaction microstructure interface is improved, and reaction continuity is improved. The solid mixture is used in high-efficiency hydrogen production, such that reaction speed and hydrogen production efficiency are improved, and the reaction is stable and controllable. The solid mixture has high application value.

Description

technical field [0001] The invention relates to a solid composition for producing hydrogen from aluminum powder. The hydrogen produced by the technology can be applied to the post-treatment industry of automobile exhaust and fuel cell vehicles, and can also be directly input into the intake pipe of a traditional internal combustion engine. Background technique [0002] At present, the world is facing comprehensive challenges of energy and environment. In order to cope with the increasingly severe energy shortage, governments and automobile companies of various countries are intensively developing new energy vehicles, including fuel cell vehicles, lithium-ion battery vehicles and super capacitor vehicles. Both lithium-ion battery vehicles and supercapacitor vehicles are facing complex electrochemical material bottlenecks. It is estimated that it will be difficult to obtain breakthrough technological progress in the next 5 to 10 years, and they will still have to rely on tradi...
