Usage
Ammonium molybdate tetrahydrate is an important molybdenum compound with a wide range of applications, mainly including the following aspects:
Catalyst Field
- Petrochemical Industry: In processes such as petroleum hydro - refining and hydro - cracking, ammonium molybdate tetrahydrate is a commonly used precursor of the active components of catalysts. It can combine with other metals (such as cobalt, nickel, etc.) to form catalysts with high activity and selectivity, which are used to remove impurities such as sulfur and nitrogen from petroleum, improve the quality of oil products, and reduce pollutant emissions.
- Coal Chemical Industry: In the processes of coal gasification and liquefaction, catalysts based on ammonium molybdate tetrahydrate can be used to promote reactions, improve the conversion efficiency of coal, and produce clean fuels and chemical raw materials.
- Other Chemical Reactions: In some organic synthesis reactions, such as the dehydrogenation of alcohols and the oxidation of aldehydes, ammonium molybdate tetrahydrate can also be used as a catalyst or a component of the catalyst to accelerate the reaction rate and improve the yield and selectivity of products.
