Hydrogen Gas H2 applications properties production storage safety
On hydrogen
Hydrogen, the genus of gas is also, and its formula is\ (H_2\). Light in weight and active, in various fields, the function is quite obvious.
1. Properties of Hydrogen
Hydrogen gas, colorless and odorless, lighter than normal gas, floating in the air. Flammable, and oxygenated, flammable, flammable, and turned into water. At room temperature, it is more lazy to react; when it encounters suitable temperature, pressure and catalysis, it can participate in various changes.
Second, the production of hydrogen
The way of its production is diverse and unique. There is a water gas conversion method, which makes carbon and water vapor co-react at high temperature to obtain hydrogen and carbon monoxide; there is also a method of electrolysis of water, which passes current on water to make water separate into hydrogen and oxygen. The hydrogen produced by this method is quite high in purity. Or by reforming fossil fuels, hydrocarbons can also be reformed by catalysis to obtain hydrogen.
Third, the application of hydrogen
In the field of industry, hydrogen is an important agent. Ammonia synthesis, hydrogen and nitrogen are combined in a catalytic, high temperature and high pressure environment to form ammonia, which is the basis for nitrogen fertilizer. In the oil refining industry, hydrogen is used for hydrorefining, removing sulfur, nitrogen and other impurities in oil, and improving oil quality. In the future of energy, hydrogen also has a grand future. Hydrogen-oxygen fuel cells, which burn hydrogen, react to generate electricity, are clean and efficient, and can supply energy for vehicles such as boats, reduce carbon emissions, and meet the needs of environmental protection.
Fourth, the storage of hydrogen
However, the storage of hydrogen is a problem. Because of its light weight, small molecules, and easy leakage. It is often stored in a high-pressure gaseous state, and a special high-pressure vessel is required to ensure airtightness; or it is liquefied at low temperature, reduced to below the boiling point of hydrogen, and stored as liquid hydrogen, which requires huge energy to maintain low temperature; there are also methods of solid-state hydrogen storage, using metal hydrides and other materials to absorb hydrogen and store it, and release hydrogen when used. The hydrogen storage rate is expected to increase in this way.
5. Safety of Hydrogen
Hydrogen is easy to ignite and explode, and it must be heavy and safe to use. In all aspects of storage, transportation and use, it is necessary to strictly set up monitoring systems to detect hydrogen leakage as soon as possible. The place must be well ventilated to avoid the accumulation of hydrogen. When electrical equipment is explosion-proof, operators must receive professional training and follow regulations to prevent the risk of deflagration and ensure the safety of personnel and facilities.
Hydrogen, although it has a wide range of applications, but the safety of storage and use still needs to be carefully researched. It is expected that it can be widely used to promote the prosperity of the industry and the beauty of the environment.
