What can hydrogen do and what can hydrogen be used for?

Hydrogen is the main industrial raw material, and it is also the most important industrial gas and special gas, which has a wide range of applications in petrochemical, electronic industry, metallurgical industry, food processing, float glass, fine organic synthesis, aerospace, etc. At the same time, hydrogen is also an ideal secondary energy source (secondary energy refers to the energy that must be produced from a primary energy source such as solar energy, coal, etc.). In general, hydrogen is readily bound to oxygen.

This property makes it a natural reducing agent for use in production to prevent oxidation. In high-temperature processing of glass manufacturing and in the manufacture of electronic microchips, hydrogen is added to a nitrogen protective atmosphere to remove residual oxygen. In the petrochemical industry, hydrogenation is required for refining by desulfurization and hydrocracking**.

Another important use of hydrogen is the hydrogenation of fats in margarine, cooking oils, shampoos, lubricants, household cleaners, and other products. Due to the high fuel properties of hydrogen, the space industry uses liquid hydrogen as fuel.

Analysis: Hydrogen is easily combined with non-metallic elements and can also form metal hydrides, which at high temperatures take oxygen from many compounds and reduce oxides. In the presence of a catalyst, hydrogen can be combined with various organic substances.

Therefore, in the process of modern industrial production, hydrogen is increasingly used as a protection to carry and reduce gases and refine certain rare metals. Metals and alloys can be treated with hydrogen to remove impurities such as phosphorus, sulfur, oxygen, and carbon, and improve the performance of metals and alloys. The uses of hydrogen can be summarized as:

1. In the electronics industry, tungsten and molybdenum wire processing; heat treatment of metal parts of vacuum tubes; extraction of semiconductor materials silicon and germanium; Epitaxial growth, device sintering, etc. in the production of semiconductor devices.

2. In the metallurgical industry, powder metallurgy is used to prepare rare metals such as tantalum, ingots, and niobium; magnet production; processing of silicon steel, etc.

3. In the chemical industry, hydrogen is used as a raw material to produce synthetic ammonia, methanol, liquid fuels and nuclear fuels; In addition, it is also used in nylon production, hydrogenation of oils and fats, etc.

4. In the gas manufacturing industry, hydrogenation and oxygen removal are often used to refine inert gases such as nitrogen and argon. Hydrogen is a combustible gas, and the hydrogen and oxygen flame can reach a very high temperature, which is used in the processing and production of hard glass, optical glass, and quartz devices.

5. In meteorological science, fill sounding balloons with hydrogen and carry sondes to an altitude of tens of thousands of meters to detect relevant meteorological elements in the atmosphere, provide data for meteorological forecasting science, and serve aviation, navigation, national defense, and industrial and agricultural construction.

6. Hydrogen plays an important role in national defense and aerospace technology. For example, liquid hydrogen can be used as a high-energy fuel for rockets or missiles. The hydrogen bomb uses solid hydrogen to produce hydrogen fusion under the action of heat energy, and releases energy to attack the enemy at the pouring moment.

Hydrogen energy, a new type of energy, will be used more and more, and it will become an inexhaustible source of energy.

In addition, hydrogen is used as a general fuel, and it also has very outstanding advantages: it is very rich in resources, it generates more heat when burning, and the heat released is about 3 times that of gasoline of the same mass, and the product produced is water, which is less polluted. Therefore, in recent years, there has been a lot of emphasis on the research of hydrogen as a new fuel.

For example, the gradual promotion of the hydrogen and oxygen welding process has improved the technological level of the product, reduced the cost and reduced environmental pollution. Hydrogen is widely used in a variety of fields. In the future, if there is a breakthrough in the technology to produce hydrogen using solar energy and water, and hydrogen can be obtained cheaply and abundantly, hydrogen will become an important new fuel.

In short, with the progress of modern science and technology, the development of industrial and agricultural production and national defense, the application range of hydrogen is expanding day by day, and the amount of hydrogen is also increasing rapidly.

The main methods of producing hydrogen in industry:

Electrolysis electrolysis electrolyzes water to produce hydrogen and oxygen. Chlorine and caustic soda are also by-products when chlorine and caustic soda are produced by electrolysis of salt solution in the chlor-alkali industry. Pure hydrogen can be obtained by electrolysis, but the power consumption is very high, and the electricity consumption is up to 1m3 of hydrogen produced.

Chemical equation: 2H2O = energized = 2H2 + O2

Hydrocarbon cracking method The cracking gas obtained by this method contains a large amount of hydrogen, and its content varies depending on the properties of the raw material and the cracking conditions. Cryogenic separation of pyrolysis gas yields hydrogen with a purity of 90, which can be used as industrial hydrogen, such as as raw material for catalytic hydrogenation in petrochemical industry.

Hydrocarbon steam reforming method Hydrocarbons can react with water vapor to produce hydrogen-containing syngas at high temperature and in the presence of a catalyst. In order to obtain pure hydrogen from syngas, molecular sieves can be used to remove other gases by pressure swing adsorption; Pure hydrogen can also be obtained by membrane separation; By adsorbing hydrogen with palladium metal, hydrogen can be separated up to 1,000 times the volume of metal.

Refinery gas Various hydrogen-containing gases produced in the production process of petroleum refineries, such as hydrogen-containing gases produced in the processes of catalytic cracking, catalytic reforming, petroleum coking, etc., and coke oven gas (containing 45 60 hydrogen) can be separated by cryogenic separation to obtain industrial hydrogen with high purity.
