1. Description :

Hydrogen is a chemical element, the symbol H, in the first place in the periodic table. The usual elemental form of hydrogen is hydrogen, colorless, odorless, odorless, is a highly combustible gas composed of diatomic molecules, hydrogen is the lightest gas. Hydrogen gas is used in medicine to treat diseases.

Hydrogen is a simple substance formed by hydrogen element, chemical formula H2, molecular weight 2.01588. At room temperature and pressure, hydrogen is a colorless, odorless, easily flammable and insoluble in water gas. Hydrogen has a density of 0.089g/L (101.325kpa,0 ° C), which is only 1/14 that of air, making it the densest known gas in the world. Therefore, hydrogen can be used as a filling gas for airships and hydrogen balloons (due to the flammability and low safety of hydrogen, airships are now filled with helium). The reaction of hydrogen with non-metals with high electronegativity shows reducibility, and the reaction with active metals shows oxidation.

Industry generally produces hydrogen from natural gas or water gas, rather than the energy-intensive method of electrolysis of water. Much of the hydrogen produced is used in cracking reactions and ammonia production in the petrochemical industry. Hydrogen molecules can enter the lattices of many metals, causing the phenomenon of "hydrogen embrittlement", which makes hydrogen storage tanks and pipes requiring special materials (such as Monel alloy) and more complicated design. In February 2018, China realized the low-temperature preparation and storage of hydrogen, which was awarded the Top Ten Scientific Advances in China in 2017 by the Ministry of Science and Technology.

1. Application:

2. Hydrogen is a good chemical raw material, the largest hydrogen consumption is synthetic ammonia, about 60% of the world's hydrogen is used for synthetic ammonia, China's proportion is higher. Second, methanol is produced from synthetic gas (H2/CO2). Hydrogen and chlorine can be synthesized into hydrogen chloride to produce hydrochloric acid. In addition to the production of ammonia and the synthesis of hydrochloric acid, hydrogen can also reduce the nitro-amino group of organic matter, such as nitrobenzene hydrogenation reduction can produce aniline. Using ketones or aldehydes and hydrogen to reduce alkylation can produce various organic products, such as n-alkyl-n-phenyl-p-phenylenediamine, antioxidant 4010, antioxidant 4020, etc.

   Because hydrogen has good reducing property and no pollution, hydrogen can replace carbon as reducing agent for metal smelting. In addition, hydrogen can also be used for optical fiber production, metal cutting and welding, hydrogen fuel cell vehicles, distributed power generation and so on. Under normal circumstances, hydrogen readily combines with oxygen. This property makes it a natural reducing agent used in production to prevent oxidation. In the high-temperature process of glass manufacturing and the manufacture of electronic microchips, hydrogen is added to the nitrogen protection gas to remove the residual oxygen. In the petrochemical industry, hydrogenation is required to extract crude oil by desulfur and hydrocracking. Another important use of hydrogen is the hydrogenation of fats in margarine, cooking oil, shampoo, lubricants, household cleaners, and other products.

   Hydrogen can also be used as an industrial fuel, one of the advantages of hydrogen as a fuel is the lowest molecular weight, and hydrogen and oxygen combustion calorific value is high, up to 28670 kcal/kg, than liquid oxygen and kerosene calorific value (about 10,000 kcal/kg) is much higher, liquid hydrogen is an excellent rocket fuel, can also be used for space shuttle propellant. It is reported that since the 1960s, China has been able to produce liquid hydrogen for the defense industry, and has built 150, 200, 1500L/h liquid hydrogen production equipment, with a total daily production capacity of several tons. In addition, the company also has a capacity of 60m ³ , 70m ³ liquid hydrogen tank trucks and a variety of specifications of liquid hydrogen road tank trucks, as well as related technical equipment in storage and transportation. China's first experimental communications satellite, launched on April 8, 1984, used liquid hydrogen and liquid oxygen propellants.

3. Studies have found that hydrogen has a good effect on anti-oxidation, anti-aging, enhancing immunity, repairing the body itself, improving allergies, and promoting metabolism.
