What is the role of phosphoric acid in the production of activated carbon?

Phosphoric acid activated carbon with husk as raw material, H3PO4 as activator to prepare can be used for citric acid, monosodium glutamate, lactic acid, xylose and other products production decolorization of activated carbon. The effects of immersion time, liquid-solid ratio, H3PO4 concentration, reaction activation time and temperature on product yield, methylene blue decolorization and caramel decolorization were studied. The yield, methylene blue decolorization and caramel decolorization of activated carbon prepared at room temperature (25 ℃) for 3 d, liquid-solid mass ratio of 2.5 ∶ 1, H3PO4 mass fraction of 65%, activation temperature and time of 550 ℃ and 1 h, respectively, were 46% 1, 3 mL and 100, respectively. Activated carbon is widely used in chemical industry, medicine, food, light industry, environmental protection, water treatment and other fields because of its developed pores and huge specific surface area.

The Function, Principle and Process of Phosphoric Acid in Phosphating Treatment

Phosphating treatment is a common metal surface treatment method. Its function is to improve the hardness, corrosion resistance and wear resistance of the metal by forming a layer of phosphide film on the metal surface. Phosphating treatment is mainly used in iron and steel materials, but also suitable for aluminum, magnesium and other metal materials.

Application of Phosphoric Acid Composite Catalyst in Petroleum Processing

Phosphoric acid catalyst is widely used in catalytic cracking process. Catalytic cracking is an important petroleum processing technology used to break down heavier crude oil into lighter petroleum products such as gasoline, diesel, and lubricants. The phosphoric acid composite catalyst can be used as a catalyst for cracking reaction, which accelerates the reaction and improves the yield and quality of the product. By regulating the composition and structure of the phosphoric acid composite catalyst, the selectivity and yield of the cracking reaction can be further optimized, and the overall processing efficiency can be improved.

In the future, the concentrated release of lithium iron phosphate production capacity will become a new force in the demand of phosphorus chemical industry.

On March 29, 2020, BYD officially launched the blade battery, announcing that its range reached the same level as the ternary lithium battery, and more smoothly passed the daunting "acupuncture test". On December 20, 2021, Guoxuan Gaoke announced that the company's overseas wholly-owned grandson company and a large listed automobile company in the United States (which one was not disclosed) signed a "strategic supply and localization agreement." According to the agreement, from 2023 to 2028, Guoxuan Gaoke will supply lithium iron phosphate batteries to this customer, who expects to purchase no less than 200GWh of batteries during the demand period. For the above large U.S. listed car companies, the industry is more speculation for Tesla. There are constantly industry giants plus code lithium phosphate track, lithium phosphate against three yuan, and have a more adequate base, or will usher in the "era of revival".

Why can phosphoric acid be so widely used? Introduction to the properties of phosphoric acid

Phosphoric acid plays a very important role in living organisms. As one of the components of ATP (adenosine triphosphate), phosphoric acid is involved in the energy metabolism of cells and is a key substance for the storage and transfer of energy in organisms. In addition, phosphate is one of the components of DNA and RNA, which is involved in the process of genetic information transmission and protein synthesis in organisms.
