PPP type deoxidizer is a liquid phase propylene-specific deoxidizer. It does not cause side reactions such as addition, polymerization, and oxidation to propylene with an unstable double bond structure. It is safe and reliable, has high deoxidation accuracy, large deoxidation capacity, and long service life.

MNOx+nO2→ MNOx+2n

This product is used to remove trace oxygen from ethylene, the raw material of the polyethylene industry.

This deoxidizer uses a special metal oxide formula that selectively deoxidizes propylene through chemical adsorption. It doesn't provide free radical reaction conditions, thus avoiding side reactions such as addition, polymerization, or oxidation of propylene double bonds.

The PPP deoxidizer can reduce the oxygen content in propylene to below 10 ppb, meeting the stringent raw material purity requirements for polymerization-grade propylene.

This product is designed for single use. Due to its high deoxidation capacity and reasonable economic considerations, regeneration is generally not recommended.

Although it is primarily designed for liquid-phase propylene deoxidation, its technology can also be applied to other hydrocarbon systems that require deep deoxidation and are sensitive to side reactions.

It must be used within the specified temperature and pressure range and avoid contact with water, sulfide and other poisons to ensure the best deoxidation effect and service life.
