Activated alumina is a porous, highly dispersed material with large surface area, microporous surface with catalytic performance, strong adsorption performance, and good thermal stability, so it is widely used as ideal material for the manufacturing of desiccant, adsorbent, catalyst, gas or water purificant.
As the most common industrial desiccant, adsorbent, activated alumina products are widely used in air separation and preparation, PSA pressure swing adsorption, gas drying, desulfurization, dechlorination and defluorination, hydrogen peroxide production, water treatment, catalyst preparation for petroleum, petrochemical and fine chemical industry.
Potassium permanganate adsorbent , purification agent adopts special alumina carrier, produced by special process, has more than twice the adsorption capacity of similar products. With its high strength and long life, it can be called the first-class product in China. Utilize the strong oxidation of potassium permanganate to oxidize and decompose the reducing harmful gases in the air, so as to achieve the purpose of purifying the air. It has high removal efficiency for harmful gases such as H2S, SO2 and HCHO. With its stronger adsorption capacity and long service life, it further oxidizes and decomposes the reducing harmful gases in the air, so as to achieve the purpose of purifying the air. It is gradually used in water treatment, vegetable preservation, meat preservation, and cold chain transportation and other fields.
