High-purity hydrogen is a colorless, odorless, and combustible gas. Flammability limit in air 40%～75.0%(v)。The autoignition temperature is 5712℃。The relative density ds(0, air = 1)006960。ρg 0.08342kg/m3(21.1℃，101.3kpa)；Liquid density 7096kg/m3(-252.8℃，101.3kpa)。Boiling point -2528℃。Melting Point - 2592℃。The hydrogen molecule is composed of two isomers, and the ratio of n-secondary hydrogen is 75:25 at room temperature. As the temperature decreases, the proportion of secondary hydrogen increases, accompanied by the release of heat of conversion. 20.The balance composition is 0 at 4k2:99.8。Hydrogen is non-toxic, but it is not life-sustaining.
Purification methodHydrogen purification methods mainly include low-temperature adsorption method, low-temperature liquefaction method, and metal hydride hydrogen purification methodIn addition, there are palladium film diffusion method, hollow fiber membrane diffusion method and pressure swing adsorption method. Hydrogen is the main industrial raw material and one of the main secondary energy sources in the future. Uses:Nuclear research, deuterium nuclear accelerator bombardment particles, tracers, can be used as gas chromatography hydrogen flame assay raw materials. Application industryPetroleum refining, float glass, electronics, food, chemical production, aerospace, automotive industry.
High-purity gas refers to a gas with extremely high purity, in which the impurity content is very low, usually at the level of ppm (parts per million) or even ppb (parts per billion). High-purity gases play an important role in modern industry and are widely used in semiconductors, optoelectronics, medical, chemical and other fields. The continuous innovation and development of high-purity gas technology has brought many opportunities and challenges, and has broad prospects in the future development. With the continuous progress of science and technology, the application field of high-purity gases is also expanding. In the semiconductor manufacturing process, high-purity gases are widely used in critical steps such as preparing photoresists and cleaning wafers. In the field of optoelectronics, high-purity gases can be used in the processing and production of lasers, optical fiber communications, flat panel displays and other equipment. In addition, high-purity gases also play an important role in the medical industry, used in the production of oxygen**, medical preparations, etc. In the chemical industry, high-purity gases can be used as reaction feedstocks or catalysts for the synthesis of high value-added chemicals.
