Product Description USAGEAlumina for DeoxidationNAMEACTIVATED ALUMINAActivated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al2O3), the same chemical substance as sapphire and ruby (but without the impurities that give those gems their color). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has. Activated alumina is good of reactivity and stability in use,especially together with our KC-201 will have good effection in sulfur recovery.Appearance: red-brown SPHERSphere Size: Φ4-6mmBulk Density: 0.70-0.75 g/cm3Crush resistance: 130Min. N/sphereSpecific Surface: 280Min. m2/g Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, in sulfur removal from gas streams (Claus Catalyst process). Activated Alumina is a form of Aluminium Oxide that is very porous andbonds with certain liquid and gases without its chemical or physicalform changing, Due to its high porosity, it has a high ratio of surfacearea to weight, it is commonly used as a desiccant, for watertreatment, and as a catalyst in natural gas and refining operations.A desiccant is a substance with a high affinity for water,which has adrying effect on its local atmosphere,such as inside a sealedcontainer,As a desiccant, Acticated Alumina operates by the process ofadsorption, thi should not be confused with the more commonly knowprocess of absorption, Absorption is a physical process by which afluids is drawn into and fills the empty spaces in a solid withoutbonding to it. Adsorption, on the other hand,is a process in which thefluid drawn into the solid material's pores actually bonds chemicallywith the solid material.When exposed to activated alumina,water molecules in the air will bondto the alumina, thereby resulting in drier air. If the material isheated, it will release the water bonded to it back into the air, Thisprocess of binding to and releaseing water can be repeatedindefinitely,making this material one of the most common desiccants.It can also adsorb other materials such as arsenic,fluoride,copper,andlead,This ability makes it a suitable candidate for use in watertreatment operations. In many cases, it is more cost-effective than acutting-edge, large-scale water treatment facility. Activated aluminawater treatment is often the method of choice for rural areas and smallmunicipal facilities.
