Introduction of gas
Biomass carbonization technology produces a variety of gas components, including nitrogen, oxygen, carbon dioxide, and water vapor.
In this process, the biomass decomposes and converts to carbon, while releasing heat to generate electricity or heat.Under different temperatures and pressures, different gas products are formed, such as water vapor, carbon monoxide, carbon dioxide, nitrogen and hydrogen, etc., which can be used for fuel, industrial smelting, deodorization and decolorization. At the same time, the generated wood vinegar and methane, hydrogen, etc., can also be further utilized.
Application of Combustible Gas
The gas components produced by biomass carbonization technology, such as carbon dioxide, nitrogen, oxygen, etc., can be applied in the following areas:
Ammonia Synthesis Process
The gas produced by biomass carbonization technology can be used to synthesize ammonia. The main steps of the ammonia synthesis process are as follows:
Biomass is converted to carbon through the carbonization process, while releasing carbon dioxide, hydrogen and other gases. These gases are one of the raw materials for ammonia synthesis.
The gas released from the biomass carbonization process contains some impurities, such as sulfide, nitrogen oxides, etc., which need to be purified. The purification process includes steps such as dust removal, desulfurization and nitrogen removal to ensure the smooth progress of subsequent ammonia synthesis.
The purified gas undergoes further chemical reactions to produce syngas. Syngas is mainly composed of hydrogen and nitrogen, and is one of the basic raw materials for ammonia synthesis.
Under the action of high temperature and pressure and the catalyst, the hydrogen and nitrogen in the synthesis gas react to produce ammonia. This process requires controlling reaction conditions, such as temperature, pressure, catalyst, etc., to improve the productivity and purity of ammonia.
Product separation and storage
The generated ammonia is separated and stored and can be used in fertilizer, chemical raw materials and other fields.
