The application of ammonium metatungstate in petrochemical catalysts can be summarized as follows:
main ingreadient
Ammonium metatungstate is the main raw material for making tungsten-based catalysts in refineries. These tungsten-based catalysts play a key role in petrochemical production, such as hydrogenation, dehydrogenation, alkylation and other reactions.
Catalyst active components
In hydrotreating catalysts, ammonium metatungstate, as an active component or additive, can significantly improve the hydrogenation activity and stability of the catalyst and help remove sulfur, nitrogen, oxygen and metal impurities in petroleum. In the dehydrogenation catalyst, ammonium metatungstate is also used as an active component, which helps to improve the conversion rate and selectivity of the dehydrogenation reaction and produce important chemical raw materials such as olefins and aromatics.
Manufacture of petrochemical catalysts
Ammonium metatungstate is not only used to manufacture tungsten-based catalysts, but also participates in the manufacture of a variety of petrochemical catalysts, such as alkylation catalysts, oxidation catalysts, etc. In these catalysts, ammonium metatungstate may serve as an active component, additive or stabilizer to improve the performance and stability of the catalyst.
Interactions with other compounds
During the preparation process of the catalyst, ammonium metatungstate may interact with other elements or compounds to form a composite catalyst with specific structure and properties. This interaction may improve the selectivity, activity or stability of the catalyst, thereby optimizing the efficiency and quality of petrochemical production.
Applications of photocatalysts
Research in recent years has shown that ammonium metatungstate can also be used as a component of photocatalysts. Under light conditions, ammonium metatungstate can promote chemical reactions, such as degradation of organic pollutants, photolysis of water to produce hydrogen, etc. This provides new possibilities for environmental protection and energy conservation in petrochemical production.
To sum up, ammonium metatungstate is widely used in petrochemical catalysts, from being used as the main raw material to manufacture tungsten-based catalysts, to being used as an active component in the manufacture of various petrochemical catalysts, to its interaction with other compounds and The application of photocatalysts reflects the important value of ammonium metatungstate in the petrochemical industry.
