Activated Alumina Ball with Sodium Permanganate

Product Introduction

Activated alumina balls are highly capable of adsorbing moisture and water vapors from the applications where air purification is must to obtain the clean product. These balls are produced by heating the aluminum oxide to the high temperature. These balls are odorless, non-toxic, insoluble in water and tasteless that makes this desiccant an ideal choice for several applications used in petrochemical and acid industry.

Activated alumina ball fluoride in similar to the anion exchange resin, but the fluoride ion selective anion resin. Activated alumina adsorption defluorization effect is good, stable capacitance, per cubic meter of activated alumina fluoride absorption 6400 grams. This product has high strength, low abrasion, water the same soft, not inflation, not pulverization, not burst. Can be widely used in petroleum cracking gas, the depth of the dry ethylene propylene gas and hydrogen production, dry air separation device, instrument air drying machine, hydrogen peroxide solution of hydrogen fluoride treatment can remove the sulfur in the exhaust gas, sulfur dioxide, hydrogen fluoride, hydrocarbon and other pollutants, especially for fluoride water fluoride in processing.

APPLICATIONS                                                                               defluorination purification for air drying; good at in the production of hydrogen peroxide solution a depth dehydration desiccant and adsorbent for polar molecules;

4.Alumina ball for drinking water application reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry;

5.used for deep drying of gas or liquid phase of petrochemicals and adsorption drying by automatic instruments;

6.has good stability, suitable for catalyst carrier and catalyst for recovering sulfur in the petrochemical industry;

7.excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzeneproduction;


  1. The main ingredients for alumina (92% or higher), has no effect on the grinding material quality.
  2. The products than the major (3.60 g/cm3) or higher, can greatly improve the grinding efficiency, reduce the milling time, save energy, reduce cost; Effectively increase mill effective volume at the same time, thereby increasing the amount of grinding material.
  3. Products high hardness, abrasion is low (0.01%) or less, can greatly prolong the service life of the grinding medium.
  4. Products with high whiteness and will not affect by the color of the grinding material.
