CATALYSTS INDUSTRY
APPLICATIONS
The production of sulfuric acids from sulfur dioxide gas with a vanadium oxide containing catalyst is well known. Vanadium oxide distinguishes itself in its stability against catalyst poisons. GfE Metalle und Materialien produces vanadium pentoxide, ammonium polyvanadate and potassium orthovanadate for the production of catalysts.
As sensitive oxygen converters, vanadium compounds are best suited for the combustion of organic starting materials. In addition, they can be tailored for forming the desired compounds with the correct functional groups for further processing. These include:
- Maleic anhydride
- Phthalic anhydride
- Adipic acid
- Acrylic acid
- Epoxides
- EPDM rubber
These organic base materials are further processed into synthetic resins, chlorine-free solvents, plasticisers, nylon, polyurethane, etc.
In its pentavalent form, vanadium is a selectively acting oxidation carrier for inorganic and organic oxidation reactions. Its effect is weaker than that of the precious metals (platinum, palladium, silver, gold) and manganese, cobalt, copper, nickel, chromium but stronger than that of zinc, magnesium, aluminum, titanium and niobium.
