Fast hydrogen producing agent

Abstract

The invention relates to a fast hydrogen producing agent. The fast hydrogen producing agent consists of aluminum, magnesium, calcium oxide, low-melting metal, a friction agent, an adhesive and an antioxidant agent in a certain proportion; the aluminum is the main function material of the hydrogen producing agent and capable of forming a plurality of activating points on the surface under the combined action of the magnesium and the low-melting metal, and then generating hydrolysis reaction in alkaline environment produced by the calcium oxide in the presence of water so as to produce hydrogen; the friction agent is used for preventing metal aluminum from clustering in the ball-milling process; the adhesive is used for processing the powdery hydrogen producing agent after ball-milling into the shape easy to pack and transport; the antioxidant agent is used for preventing the hydrogen producing agent from oxidizing so that the hydrogen producing agent can be stored for a long time. The fast hydrogen producing agent provided by the invention has the advantages of low cost, stable property and high hydrogen producing efficiency and can be widely applied to instantaneous-preparation and instantaneous-application occasions of mobile hydrogen energy.

Description

technical field [0001] The invention relates to a rapid hydrogen production agent, in particular to a solid mixture with low cost, stable properties, high hydrogen production efficiency and rapid hydrolysis when meeting water to generate hydrogen. Background technique [0002] Hydrogen energy is a kind of energy with high energy density and green environmental protection. It has a very wide range of applications in vehicle power systems, laptop computer power supplies, emergency power supplies, and individual combat power supplies. However, due to the flammable and explosive characteristics of hydrogen, its transportation is difficult, which hinders its large-scale application. Therefore, it is of great significance to develop ready-to-use hydrogen energy technology. [0003] At present, the commonly used instantaneous hydrogen production technology mostly adopts aluminum hydrolysis method, but the dense oxide film on the aluminum surface hinders the contact between aluminu...

Problems solved by technology

However, calcium and lithium have strong activity, and the final composite hydrogen generator is extremely unstable in the air, which is not conducive to storage

At the same time, the cost of active materials such as bismuth, lithium, and calcium is high, and the cost of the final hydrogen-generating agent is relatively high.

[0004] In addition, the aluminum particles in the existing hydrolysis hydrogen production agent are easy to agglomerate during the ball milling process, and the repeated ball milling process is cumbersome, time-consuming, and reduces the activity of the hydrogen production agent

What's more serious is that the high surface activity aluminum-based hydrogen generator (especially mixed with high activity metals such as lithium calcium and other metals) is prone to surface oxidation effect, easy to fail, short shelf life, and poor practicability
