Various usages of Hydrogen

1.Petrochemical industry production: as the raw material gas of hydrogenation of ammonia, methanol, petroleum refining, etc. As well as  organic materials of organic hydrogenation.
2.Metallurgical industry: it is widely used in the production and processing of tungsten, molybdenum and titanium just as reduction gas and protection. And it used in production and rolling of thin steel plate, strip steel strip and silicon steel sheet;Production of precision alloy, powder metallurgy material.
3.Electronics industry: mainly used in the production of electronic materials, semiconductor integrated circuits and electro-vacuum main devices.
4.Building materials and light industrial production: as protective gas and combustion gas, such as quartz glass and artificial gemstone production, hydrogen monoxide is used to obtain high temperature;In float glass production,hydrogen is used for protect gas and so on.
5.Power industry: as a coolant for generator sets.
6.Balloons and airbags: as filling gas.
7.Liquid hydrogen is an important liquid fuel for aerospace and rocket.
8.Make fuel cells with hydrogen.
9.It has come true that we can use hydrogen fuel in cars and dispose of chemical waste products
