Activated alumium oxide, also known as activated alumina,. The use of alumina in the catalyst is usually called "activated alumina". It is a porous, highly dispersed solid material with a large surface area, and its microporous surface has the characteristics required for catalysis, such as Adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions. Spherical activated alumina pressure swing oil adsorbent is white spherical porous particles. The activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, it does not swell or crack after absorbing water, and remains in its original state, non-toxic, odorless, and insoluble Water & ethanol. Activated alumina is a kind of high-efficiency desiccant for deep drying of trace water, suitable for non-heat regeneration device.
Activated alumina belongs to the category of chemical alumina and is mainly used in adsorbents, water purifiers, catalysts and catalyst carriers. Activated alumina has selective adsorption capacity for gas, water vapor and some liquid moisture. After the adsorption is saturated, it can be revived by heating at about 175-315°C to remove water. Adsorption and resurrection can be performed multiple times. In addition to being used as a desiccant, it can also adsorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. It can also be used as catalyst and catalyst carrier and chromatography analysis carrier. It can be used as a defluorinating agent for high-fluorine drinking water (large fluorine removal capacity), a defluorinating agent for circulating alkanes in the production of alkylbenzene, a deacidification regenerator for transformer oil, and a gas drying agent in the oxygen industry, textile industry, and electronics industry , Automatic instrument wind drying and desiccant and purifying agent in chemical fertilizer, petrochemical drying and other industries (the dew point can reach -40ºC), and the pressure swing adsorption dew point can reach -55ºC in the air separation industry. It is an efficient desiccant for deep drying of trace water. It is very suitable for non-heat regeneration devices.
