Ammonia is an important inorganic chemical, widely used in agriculture, industry, energy and other fields. In the field of chemical production raw materials, the upstream and downstream related products of synthetic ammonia are very rich. This article will detail the upstream and downstream associated products of synthetic ammonia.

1. ammonia synthesis upstream product

1. Natural gas

Natural gas is one of the main raw materials for synthetic ammonia production, and its main component is methane. Natural gas is converted into synthesis gas (a mixture of hydrogen and nitrogen) by steam reforming or partial oxidation, and then purified, compressed, and synthesized to produce synthetic ammonia.

2. Coal

Coal is also one of the important raw materials for the production of synthetic ammonia. Coal is converted into synthesis gas through gasification, and then through purification, compression, synthesis and other processes to produce synthetic ammonia.

3. Air

Nitrogen in the air is another important raw material for ammonia synthesis. Through air separation technology, nitrogen in the air can be separated for the production of synthetic ammonia.

2. ammonia synthesis downstream products

1. Urea

Urea is a commonly used nitrogen fertilizer, but also one of the main downstream products of ammonia synthesis. The production of urea usually takes synthetic ammonia and carbon dioxide as raw materials and reacts to produce urea.

2. nitric acid

nitric acid is a strong acid, widely used in chemical, pharmaceutical, pesticide and other fields. The production of nitric acid usually takes synthetic ammonia and oxygen as raw materials, and generates nitric acid through oxidation reaction.

3. ammonium salt

ammonium salt is a kind of important inorganic compounds, widely used as chemical fertilizer, chemical raw materials, etc. The production of ammonium salt usually takes synthetic ammonia and acid as raw materials, and generates ammonium salt through neutralization reaction.

4. Amide

Amide is an important class of organic compounds, widely used as solvents, plastics, fibers, etc. Amide production is usually synthetic ammonia and organic acids as raw materials, through the amidation reaction to produce amide.

In short, the upstream and downstream related products of synthetic ammonia are very rich, involving many fields, such as agriculture, chemical industry, medicine and so on. With the continuous development of science and technology, the upstream and downstream products of synthetic ammonia are also expanding and extending, providing important support for the development of various fields.
