Catalytic oxidation is of wide and vital importance in fine chemical engineering that enables reformations of hydrocarbon materials (olefins, aromatics, alkanes) into a variety of multi-functional derivatives.

Oxidation reactions have the following characteristics:

*The reaction is accompanied by a huge amount of heat releases. And as reaction proceeds gradually, heat release will increase correspondingly.

* The reaction is irreversible. Hydrocarbon oxidation reaction ΔG << 0 can violate the rule of chemical equilibrium。

* The realization of reaction is complex and diverse.

* The reaction process possesses possibility to cause fire and explosion.
