Example Embodiment

[0024] Example 1:

[0025] In a hydrogen production reaction capable of controlling the rate of hydrogen production, the solid catalyst is mainly a mixture of sodium hydroxide and sodium bicarbonate, wherein the mass fraction of sodium hydroxide is 50% and the mass fraction of sodium bicarbonate is 50%. The mass fraction of aluminum powder in the hydrogen generator is 79%, and the remaining slow-release agents and other ingredients account for 21%. The buffer is mixed with 5% magnesium stearate and 95% sodium carboxymethyl cellulose. The composition, the ratio of hydrogen generator to solid catalyst is 1:0.5.

[0026] The above mixture is processed into flakes by mixing, tableting and other techniques, and packed in a non-woven fabric. When in use, mix the non-woven fabric bag with hydrogen generator and catalyst and room temperature water at a ratio of 1:10, and the hydrolysis reaction lasts for about 160 minutes.

Abstract

The invention belongs to the technical field of chemical engineering and provides a hydrogen production reaction with the controllable hydrogen production speed to solve the problem that the hydrogen production rate is affected due to different degrees of alkalinity in a traditional aluminum water hydrogen production method and the problem that manual control cannot be achieved due to the high hydrogen production speed generated when PH is too high.The hydrogen production reaction includes the process that a hydrogen production agent generates a hydrolysis reaction under the effect of a solid catalyst.The alkaline solid catalyst is added in the process of mixed hydrogen production of a hydrogen-from-aluminum agent and a sustained-release agent, the hydrogen production rate and time period can be effectively controlled, and hydrogen is generated at a uniform speed for use.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a hydrogen production reaction capable of controlling the hydrogen production speed. Background technique [0002] At present, hydrogen energy (fuel cell) is considered to be the first choice to solve carbon emissions, but because infrastructure such as hydrogen supply stations seriously restricts its development, it is urgent to develop efficient, safe and rapid online hydrogen supply technology. [0003] The production of hydrogen can be achieved through different technical means, including electrolytic hydrogen production, pyrolysis hydrogen production, photochemical hydrogen production, radioactive hydrolysis hydrogen production, chemical hydrogen production and biological hydrogen production and so on. At present, most of the hydrogen is produced through natural gas steam reforming reaction or partial oxidation, but the resources are limited and a large...
