Activated alumina is a porous, highly dispersed material with large surface area, microporous surface with catalytic performance, strong adsorption performance, and good thermal stability, so it is widely used as ideal material for the manufacturing of desiccant, adsorbent, catalyst, gas or water purificant.
As the most common industrial desiccant, adsorbent, activated alumina products are widely used in air separation and preparation, PSA pressure swing adsorption, gas drying, desulfurization, dechlorination and defluorination, hydrogen peroxide production, water treatment, catalyst preparation for petroleum, petrochemical and fine chemical industry.
Activated alumina , white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity. It has the characteristics of large adsorption capacity, large specific surface area, high strength, and good thermal stability. In the construction of activated alumina: the spherical particles of activated alumina have many pores and are highly polar to water and other molecules. It has a strong affinity and is a non-toxic, non-corrosive desiccant with a high static capacity. In the petroleum, chemical fertilizer, chemical and other industries, it is used as an adsorbent and desiccant during the reaction process. Activated alumina desiccant is one of the most widely used inorganic chemical products in the world.
Under certain operating conditions and regeneration conditions, the drying depth of this product is as high as the dew point temperature below -70 degrees. This product can be used for gas drying in the electronic industry, drying of automatic instrument air, and drying in chemical fertilizer, steel, petrochemical and other industries. It is a high-efficiency desiccant for deep drying of trace water, which is very suitable for heatless and slightly heat regeneration devices. Widely used in gas and liquid phase drying of petrochemical industry, drying of textile industry, oxygen production industry and automatic instrument air, pressure swing adsorption in air separation industry, etc.
