The role of activated alumina
The use of alumina in the catalyst is commonly referred to as "activated alumina", which is a porous, highly dispersible solid material with a large surface area and a microporous surface with the properties required for catalysis, such as It is widely used as a catalyst for chemical reactions and a catalyst carrier because of its adsorption properties, surface activity, excellent thermal stability and the like. So what is the role of activated alumina?
After the adsorption is saturated, the water can be removed by heating at about 175-315 ° C for reactivation. Adsorption and resurrection can enter Do it many times. In addition to being used as a desiccant, it can also be contaminated with oxygen, hydrogen, carbon dioxide, natural gas.The vapor of the lubricating oil is adsorbed. And can be used as catalyst and catalyst carrier and chromatography analysis body.
Activated alumina belongs to the category of chemical alumina, mainly used in adsorbents, water purifiers,The catalyst and the catalyst carrier have different raw materials and preparation methods depending on the application.Drying depth of activated alumina under certain operating conditions and regeneration conditions Up to dew point temperature -70 degrees or less, [activated alumina use]: This product can be used as high Defluorination agent for fluorine drinking water (large in fluorine removal capacity), defluorination agent for circulating alkane in alkylbenzene production,
