Micronized zinc oxide powder has a wide range of applications in desulfurization agents. Zinc oxide desulfurization technology is to add water containing micronized zinc oxide powder or the washing liquid of the desulfurization residue returned in the process into a suspension, and react with the SO2 in the flue gas in the absorption equipment, and the SO2 in the flue gas is mainly zinc sulfite ( There are also the form of zinc bisulfite, zinc sulfate) to be removed. The absorbed by-product zinc sulfite undergoes air oxidation or thermal decomposition or acid decomposition treatment, and finally products such as zinc sulfate, electrolytic zinc and sulfuric acid (or liquid sulfur dioxide) can be produced.

The main indicators of PZT-01 normal temperature zinc oxide desulfurizer and PZT-02 medium temperature (high temperature) zinc oxide desulfurizer produced withmicronized zinc oxide powder are as follows:

*Appearance and specifications: The external form of zinc oxide desulfurizer is in the shape of yellow and white clover, and the specifications are diameter Φ4~5×3~20mm.

*Composition: The main components are fine zinc oxide powder and active components (above 95%)

*Specific surface area: the larger the specific surface area of the zinc oxide desulfurizer, the larger the contact area with hydrogen sulfide gas, and the faster the reaction rate.

*Sulfur capacity: It is an important indicator to measure the quality of zinc oxide desulfurizer. It refers to the kilograms of sulfur that can be absorbed per 100 kilograms of zinc oxide desulfurizer, usually expressed as a percentage. The penetration sulfur capacity of the zinc oxide desulfurizer produced by MSTmicronized zinc oxide powder is as high as 35%. The penetration sulfur capacity is the capacity of the zinc oxide desulfurizer per unit volume to absorb sulfur while ensuring the process purification index.

*Crushing strength: The higher the percentage, the better the crushing resistance.
