What are the technologies for hydrogen production?

The technologies for hydrogen production are:

1. Fossil Fuel Hydrogen Production

Fossil Fuel Hydrogen Production is a traditional method of hydrogen production and an old process. However, it still relies on fossil fuels and will emit greenhouse gases such as carbon dioxide. The fossil fuel usually used for hydrogen production is natural gas. There is an extreme shortage of natural gas in the country, the feedstock is underutilized, and the process of making it is complex and difficult. The location of natural gas hydrogen production construction is also very much influenced by the availability of natural gas.

2. Methanol reforming method

Methanol steam reforming method is a kind of hydrogen production technology developed abroad in the 1980s, which has low investment, quick completion, no emission and no pollution, and high availability of raw materials. So far the hydrogen production process at home and abroad is very mature, highly integrated technology and fuel cell power generation technology, in new energy vehicles, communication stations and other areas of successful application, the application prospects are very good.

3. Industrial by-products of hydrogen production

Coke oven gas is the use of variable pressure adsorption process of hydrogen production process, from the coking industry by-products of coke oven gas in the extraction of pure hydrogen, the basic principle is the use of solid adsorbent selective adsorption of gases and gas adsorption on the adsorbent with the reduction of partial pressure of gas mixing and separation and regeneration of the adsorbent characteristics, to achieve the purification of hydrogen production purposes

4. Hydrogen production by electrolysis of water

Traditional electrolysis of water can also obtain hydrogen, domestic and foreign use of electrolysis of water to produce hydrogen technology is relatively mature, high efficiency, hydrogen production process is simple. However, this method has few new installations except those already built due to its high cost.

Hydrogen role:

1, in the petrochemical industry, the need for hydrogen through the de-sulfurization and hydrogenation cracking to refine crude oil.

2, another important use of hydrogen is the hydrogenation of fats in margarine, cooking oil, shampoo, lubricants, household cleaners and other products.

3, in the high-temperature process of glass manufacturing and the manufacture of electronic microchips, hydrogen is added to the nitrogen protective gas to remove residual oxygen.

4, used as raw material for ammonia synthesis, methanol synthesis, hydrochloric acid synthesis, metallurgical reducing agent.

5, due to the high fuel properties of hydrogen, the aerospace industry uses liquid hydrogen as fuel.
