Activated Alumina
Activated Alumina Balls can be used as absorbent, desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole-moleculae absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali ect..
Activated Alumina ball are comprised of a synthetically-produced aluminum oxide (A12O3) in a smooth spherical form with high-crush strength. It is highly porous and can have a high surface area greater than 300m2/g. It is an excellent desiccant for liquids and gases, and can achieve dew points from -40°C depending on the operating conditions and the design of the dryer. It will adsorb many molecules to some degree, but will preferentially adsorb the molecules with the highest polarity.Why Choose Activated Alumina for Air Drying?
Activated Alumina ball works as a desiccant through adsorption, so as air passes through the desiccant beads, the water in the air sticks to it and becomes trapped, enabling the air that passes through the activated alumina filter to become dried out. Even if immersed in a liquid, the beads will not fall apart or soften.
Activated Alumina balls can be restored to its original adsorption efficiency by heating the desiccant to any temperature from 177° to 316°C. When the desiccant is heated as described above, the water stored in it is released, which enables the Activated Alumina filters to be reused over and over again.
• Catalyst for recovering sulfur in the petrochemical industry
• Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production
• Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry
• Adsorbent in the production of hydrogen peroxide solution
• Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product
• Desiccator and purifying agent.
Activated Alumina ball is extremely effective for drying gases and is very stable physically and chemically, even in high temperature and corrosive environment. It is widely used for compressed air dryers, because of its cost effectiveness in relation to the other types of desiccant. With its high surface area, high moisture capacity, and high crush strength, the desiccant beads can easily withstand the saturated conditions that are found within an air compressor.
• Quality Assurance
• Price Advantage
• Good Before& After Service
• While they often perform the same process of adsorbing moisture, activated alumina and molecular sieve differ in many ways. Molecular sieve features pores whose size can be adjusted by ion exchange, allowing them to separate molecules based on size discrimination, a task other adsorbents are not capable of.
• The sizes of the pores of activated alumina cannot be tailored and are not necessarily uniform. However, activated alumina has its own pros. Activated alumina shows a higher affinity for water than molecular sieve, so it is often used in the drying of various gas and liquid streams, instances when it is important to adsorb the most moisture possible. Its high crush strength allows activated alumina to withstand the high pressures of industrial applications.
