where is activated alumina used
Activated alumina is what we often call activated alumina and activated alumina desiccant. It has a large surface area and strong adsorption capacity. It has selective adsorption capacity for gas, water vapor and moisture in certain liquids. After the adsorption is saturated, it can be revived by heating at about 175-315°C to remove water. Adsorption and resurrection can be carried out 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 a catalyst and a catalyst carrier and a chromatographic analysis carrier. Next, let's take a look at its role.
Activated alumina is mainly used in adsorbents, water purifiers, catalysts and catalyst carriers. According to different uses, the raw materials and preparation methods are different. Under certain operating conditions and regeneration conditions, the drying depth of the product is as high as the dew point temperature-70 degrees or less.
Activated alumina 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 as an oxygen-making industry, textile industry, and electronics Industrial gas drying, automatic instrument wind drying, as desiccant and purifying agent in chemical fertilizer, petrochemical drying and other industries (the dew point can reach -40 degrees), and the pressure swing adsorption dew point can reach -55 degrees in the air separation industry. It is a desiccant with trace water depth. It is very suitable for non-heat regeneration devices.
The above is the purpose of activated alumina, have you understood through this article? Only when we have a deeper understanding of activated alumina can we use it better.
