Chemical activated alumina desiccant chloride adsorbent gamma aluminium oxide for deflorination in hydrofluoric alkylation
Activated Alumina, there are many micro-paths, so the specific surface is large. It can be used as absorbent, desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole molecular absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali ect. Activated alumina defluorinate just as the anion exchange resin, but the selectivity is much strong. The defluorinate effect of the activated alumina is good. The capacity is stable. It has high strength, low abrasion, no soften in water, no expansion, no powdery no crack. It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorinate.
Typical Application
Activated Alumina KA100 for TBC removal in production of polyethylene and polymer
Activated Alumina KA401 for ordinary gas and liquid dehydration
Activated Alumina KA402 for arsenic and fluoride removal in water treatment
Activated Alumina KA403 for absorption in producing hydrogen peroxide (H2O2)
Activated Alumina KA404 for catalyst carrier
Activated Alumina KA405 for dehydrating and drying in air separation
