Activated alumina belongs to the scope of alumina chemicals, mainly used in absorbents, water purifiers, metal catalysts and catalyst carriers. Activated alumina has the ability to selectively adsorb gases, water vapor and moisture from some solutions. After adsorption saturation, it can be regenerated by heating at about 175-315°C to remove water. Adsorption and regeneration can be achieved multiple times.
In addition to being used as a moisture-proof agent, it can also absorb grease vapor from environmental pollution such as oxygen, hydrogen, carbon dioxide, and natural gas. And can be used as metal catalyst and catalyst carrier and chromatographic analysis medium.
It can be used as a defluorinating agent for high-fluorine drinking water (large defluorinating volume), a defluorinating agent for ethane in the circulation system in the production of alkylbenzene, a deacidifying and regenerating agent for insulating oil, used for oxygen production, textile industry , Gas drying in the electronic industry, drying of automated instrument air, and its use as a moisture-proof agent and purifier in the fields of fertilizers and petrochemical equipment drying (the leakage point can reach -40°C), and the leakage point of pressure swing adsorption in air enterprises can reach -55°C.
It is also a high-efficiency moisture-proof agent for deep drying with a small amount of water, which is very suitable for non-heat regeneration equipment.
