Application of Coal Hydrogen Production Technology

Hydrogen is widely used in fields such as electronics, metallurgy, glass production, chemical synthesis, aerospace, direct coal liquefaction, and hydrogen energy batteries. Currently, 96% of the world's hydrogen comes from the conversion of fossil fuels. Coal gasification plays a very important role in hydrogen production. Generally, coal is converted into CO and H2, and then CO is converted into H2 and H2O through a transformation reaction. Hydrogen rich gas can be obtained by low-temperature separation, pressure swing adsorption, and membrane separation technology. In practical applications, the increase in CO content will inevitably lead to an increase in the load of the converter in the transformation process. It not only shortens the service life of the catalyst, but also increases the steam consumption of the converter.used forGas composition analysis provides concentration data of various gas components in gas, guiding the control of gasification and conversion processes, which can play a role in energy conservation and efficiency improvement.

It can also improve chemical production efficiency, provide clean energy, improve process technology, and achieve maximum benefits in the application of coal gasification polygeneration, which helps to enhance industrial technology level.

With the application and development of coal gasification technology in China, higher requirements have been put forward for the monitoring and control of the coal gasification process.It can achieve component analysis and calorific value analysis of coal gas. The problems of H2 measurement compensation and CH4 measurement anti-interference have been solved in practical applications, and are more widely used in industrial gas, civil gas, metallurgy, chemical and other industries. It can guide process control and improvement, and achieve energy-saving and efficiency enhancing effects, which is conducive to promoting the improvement of gasification technology.
