Activated Alumina

Activated alumina Type χρ active alumina desiccant is kind of spherical hard granule full of many invisible fine pore .It is no corruptive ,non toxic ,and has close affinity to polar molecule ,This product is typically used as effective desiccant it has high adsorption capacity for moisture deep dew point control (-70),and low regeneration temperature (150),it is widely used in petrol chemical, textile and air-separation field Formula :AL2O3 Activated alumina desiccant Item3-5mmSphere4-6mmSphereBulk density g/ml≥0.70≥0.68Surface area sqm/g260-300260-300Pore volume ml/g0.38-0.420.38-0.42Static adsorption (RH=60%)16-1816-18Crushing strength N/P≥90≥120Abrasion (%)≤0.40≤0.40Remarks: Do not unpack the package before using in order to avoid damp This product can control the dew point to -70. This product can be used and regenerated again and again. Packing: 25kg plastic woven bag or 150kg steel drums. Other types of active alumina: Type γ catalytic active alumina ,can be used as catalyst carrier of catalyst itself. χρ active alumina can be used as defluoride in water process ,fluoride removal capacity can reach to 2.1mg/g. χργ active alumina for dioxide hydrogen purification. χρ Active alumina for oil purification
