Molecular Formula: H2
Main use:
The initial use of hydrogen is the hydrogen balloon, hydrogen airship. At present, two-thirds of the world's production of hydrogen for the ammonia system. Second, it is used in oil refining and petrochemical industries in a variety of processes, such as hydrocracking, catalytic hydrogenation, hydrotreating, hydrodesulfurization, benzene hydrogenation to cyclohexane, naphthalene hydrogenation of decalin, etc. . The third is the production of methanol. In addition, hydrogen is also used for hardening of plant and animal oils and fats, such as the manufacture of margarine, brittle butter, grease and so on.
Products:
H2 is an important industrial gases. Colorless, tasteless, odorless, flammable. Atmospheric pressure boiling point -252.8 ℃, the critical temperature of -239.9 ℃, the critical pressure of 1.32MPa, the critical density of 30.1g / l. In the air content of 4% ~ 74% (volume), that is to form an explosive mixture of gases. Hydrogen is the lightest material, with oxygen, carbon, nitrogen were combined into water, hydrocarbons, ammonia and so on. Natural gas fields, coal fields, as well as fermentation of organic matter, also contains a small amount of hydrogen.
