Hydrogen energy is considered to be an important form of energy in the future energy field. It has the advantages of high efficiency, clean and renewable, and is an ideal alternative energy. However, the production of hydrogen has become one of the constraints of hydrogen energy. The traditional hydrogen preparation technology mostly uses fossil fuels (such as natural gas, petroleum, etc.) as raw materials, and uses high temperature and high pressure to carry out chemical reactions, resulting in high production costs, high energy consumption, environmental pollution and other issues. Therefore, looking for an efficient, clean and environmentally friendly hydrogen production technology is one of the important topics in the development of hydrogen energy industry.

pressure swing adsorption hydrogen production technology is a new type of hydrogen production technology, its principle is to use the different characteristics of raw gas adsorption and desorption at different pressures, through repeated pressurization and decompression, can separate high-purity hydrogen. Compared with the traditional hydrogen production technology, pressure swing adsorption hydrogen production technology has the following advantages:

1. energy consumption is small. In the pressure swing adsorption hydrogen production technology, there is no need to use high temperature, high pressure and other conditions, so the energy consumption is very small. Compared with the traditional hydrogen preparation technology, it can save more than 70% of energy.

2. low production costs. The pressure swing adsorption hydrogen production technology does not require the use of expensive raw materials, and the production cost is reduced by more than 30% compared with the traditional hydrogen production technology.

3. environmental benefits. Pressure swing adsorption hydrogen production technology will not produce waste water, waste gas and other pollutants, no pollution to the environment, and can realize the recycling of waste gas, with high environmental benefits.

4. a wide range of applications. Pressure swing adsorption hydrogen production technology can produce high purity hydrogen, which is widely used in aerospace, chemical, electronics, pharmaceutical and other industries.

5. sustainable development. Pressure swing adsorption hydrogen production technology can improve the sustainability and development potential of the hydrogen industry and promote the development of the hydrogen energy industry.

Therefore, pressure swing adsorption hydrogen production technology is considered to be an important technical means in the future hydrogen energy production. In practical applications, it is necessary to continue to strengthen technology research and development, optimize process flow, and strengthen safety management to ensure the efficient, safe, reliable, environmentally friendly and sustainable development of PSA hydrogen production technology.
