The core application of tungsten trioxide(WO3)catalyst supported on alumina(Al2O3)is to utilize the synergistic effect oftheacidity oftungsten trioxideandotheractive components,playing a key role in petroleum refining,environmental protection,and chemical synthesis.Mainly manifested in:flue gas denitrification(SCR).
As a co catalyst added to vanadium based SCR catalysts,it can significantly improve denitrification performance and hydrothermal stability.It can also promote the oxidation of NO to NO2,enhance low-temperature activity,and maintain high activity under harsh conditions containing SO2 and H20;Hydrogenation treatment.

As an active component used in the hydrogenation desulfurization and denitrification of gasoline and diesel,it can effectively prevent catalyst sulfur poisoning,and is also used in the hydrogenation deacidification of distillate oil and deep hydrogenation of naphthalene;Synthesis gas production:
As a promoter added to nickel based catalysts for methane dry reforming reactions,it can significantly improve the ability toresist carbon deposition.It can also be used for alcohol dehydration,fine chemical oxidation,isobutene oligomerization,photocatalysis,etc.
