Embodiment 1

[0035] Example 1: Using metal aluminum as a carrier, the system is used as a hydrogen source for a hydrogen-burning engine

[0036] Aluminum is made into a metal with a high specific surface area, such as metal aluminum powder with a diameter of about 50 μm, and reacts with water at a ratio of 1:3. The actual amount of 27 kg of metal aluminum powder and 54 kg of water is added to the Into the reaction vessel, about 50 mg of a catalyst such as sodium borate is then added while the reaction vessel is sealed.

[0037] Connect the gas outlet of the reaction vessel with the hydrogen inlet of the gas engine, start the gas engine, react with the aluminum powder and water, and start supplying gas to the gas engine.

[0038] After calculation, the energy generated by it can support an ordinary family car (fuel consumption 10 liters / 100 kilometers) to travel 100 kilometers.

[0039] After the reaction is over, the reaction container is recycled through the recovery system, and aluminum...

Abstract

The hydrogen energy circulation system by using metal with high specific surface area as carrier includes the following steps: (1) utilizing existent wet smelting technique to prepare energy storage metal with high specific surface area by using metal hydroxide so as to implement storage of electric energy; (2) utilizing material interchange station to implement interchange of energy storage metal and waste material; and (3). in the presence of catalyst making metal with high specific surface area and water implement reaction so as to produce waste material and hydrogen gas, in with the hydrogen gas can be provided for hydrogen energy consumption mechanism to use. The above-mentioned metal with high specific surface area can be metal aluminium or its alloy and metal magnesium or its alloy. Said invention can be used for matched equipment of hydrogen source car, fuel cell or other energy conversion system.

Description

technical field [0001] The invention relates to a hydrogen energy storage, conversion and circulation method using a metal with a high specific surface area as a carrier. Background technique [0002] Electric energy is currently the cleanest energy in the process of use among various energy sources, but electric energy will be lost in a large amount during the transmission process. The traditional electric energy storage method using batteries as the main carrier, on the one hand, the stored electric energy is limited, on the other hand, the battery itself is difficult to recycle, which will cause serious pollution to the environment. With the continuous development of technologies such as hydrogen vehicles and fuel cells, hydrogen energy has become a very important alternative energy due to its high calorific value and no pollution after combustion. However, there are always problems such as leakage and explosion in the hydrogen storage and supply system. Contents of th...
