This product is used for reclaiming degradation product in the working fluid in hydrogen peroxide production by Anthraquinone Method. Especially in the plants of palladium catalyst and three-component nickel catalyst, there is no other better method for degradation except activated alumina, this kind of special absorbers, which is indispensable to hydrogen peroxide production.
Many tests, valuations and application in hydrogen peroxide can show that this product, compared with other similar products, is the perfect one at home at present, also has many good properties such as, less floating powder, low abrasion quantity, big specific surface area, good degradability, long life period.
