Main applications
1. Hydrogen is the main industrial raw material, but also the most important industrial gas and special gas, in petrochemical, electronic industry, metallurgical industry, food processing, float glass, fine organic synthesis, aerospace and other aspects have a wide range of applications. At the same time, hydrogen is also an ideal secondary energy source (secondary energy refers to energy that must be produced by a primary energy source such as solar energy, coal, etc.). In general, hydrogen combines easily with oxygen. This property makes it a natural reducing agent for use in production that prevents oxidation. In the high-temperature processing of glass manufacturing and the manufacture of electronic microchips, hydrogen is added to the nitrogen shielding gas to remove residual oxygen. In the petrochemical industry, crude oil is refined by hydrogenation through 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 hydrogen's high fuelicity, the space industry uses liquid hydrogen as fuel.
2. Used as raw materials for synthesizing ammonia, synthesizing methanol, synthesizing hydrochloric acid, reducing agent for metallurgy, hydrodesulfurization agent in petroleum refining, etc.
