The difference between activated alumina and activated carbon

Activated alumina is a kind of porous, high dispersion of solid materials, has a large surface area, the microporous surface has the characteristics of catalytic action required, such as adsorption performance, surface activity, excellent thermal stability, etc..As a desiccant, catalyst, fluoride removal agent has a very significant effect.Activated alumina adsorbent for white spherical porous particles, activated alumina particle size uniform, smooth surface, high mechanical strength, hygroscopicity, water absorption does not expand does not crack to maintain the original state, non-toxic, odorless, insoluble in water, ethanol.Activated alumina is an efficient desiccant for deep drying with trace water and is suitable for non-heat regeneration device.

Secondly, to understand the activated carbon.Activated carbon is divided into coconut shell activated carbon, nut shell activated carbon, columnar activated carbon, honeycomb activated carbon bee according to the appearance of different, so no matter which activated carbon has a certain adsorption.Activated carbon can not only remove all kinds of harmful substances in the water but also adsorb harmful gases in the air.For example, columnar activated carbon as a household formaldehyde removal is a very good product.Using activated carbon adsorption method to remove indoor pollution is the most widely used, the most mature, the safest, the most reliable effect, the most kinds of absorption of a kind of method.Activated carbon, as an excellent physical and chemical adsorbent, has attracted more and more attention.Efficient environmental protection activated carbon pack can absorb formaldehyde, ammonia, benzene, xylene, radon and other indoor harmful gas molecules in the air, quickly eliminate decoration odor.

Both activated alumina and activated carbon are now well known and used.Their common characteristic is non-toxic, tasteless, harmless, each industry has their figure.
