Molecular Sieve Alumina Bead

Activated alumina 2 - 5 mm is highly porous material; this material can have a surface area significantly over 200 square metres/g. Very suitable for use as a filter of fluoride, arsenic and selenium in drinking water.

Remarks

High quality activated alumina for applications such as catalysts adsorption in polyethylene and hydrogen peroxide production, selective adsorption of chemicals from gas streams, and removal of fluoride from drinking water. We also provide activated alumina that can be used as a desiccant in many other applications, including compressed air drying.

Note

Activated Alumina Desiccants:

Activated Alumina Desiccants is a porous form of aluminum oxide. It has a high surface area which adsorbs vapors without any change in form. Activated Alumina Desiccants  will not soften or disintegrate easily when immersed in water.

Dew points to -40°F and lower may be achieved with Activated Alumina Desiccants  depending on dryer design and operating conditions.

The 1/8” (2-5mm) bead is the size most frequently used in regenerative dryers.

If size is not known or specified, the 1/8” (2-5mm) size is usually satisfactory. However, if Activated Alumina Desiccants is used in a regenerative dryer and the desiccant retaining screens cannot be measured, the 1/4” (5-10mm) size should be used as a bed support (6” layer). If at all possible, obtain a sample and measure it  before ordering.

Product Benefits:

  1. High adsorption capacity. With high surface area and excellent pore distribution, Activated Alumina Desiccants  has a high water adsorption capacity. This reduces initial cost, energy consumption and operating costs through smaller bed sizes and/or longer operating cycles.
  2. Low abrasion. Insures less dusting during tower depressurization or loading. Low abrasion means low pressure drop and a reduced chance of plugging the afterfilter.
  3. Resists liquid water. Water slugging due to upstream failure of aftercooler, separators or drain traps will not fracture the alumina beads. The adsorption capacity of the desiccant can be restored after complete regeneration.
  4. High crush strength. High crush strength, which limits dusting, is important during loading of desiccant towers. High crush strength makes alumina effective as a prebed material when used with other types of desiccants.
  5. Uniform bead sizes. Activated Alumina Desiccants is a uniformly sized bead. It provides low pressure drop to minimize channeling and ensures utilization of the full bed column section.
Activated Alumina is an aluminium oxide that is highly porous and exhibits tremendous surface area. Activated Alumina is resistant to thermal stock and abrasion and will not shrink, swell, soften nor disintegrate when immersed in water.
 
Surface area is in the range 345-415. Because it has a higher capacity for water than Silica Gel at elevated temperatures it is mainly used as a desiccant for warm gases including air. In many commercial applications zeolitic materials have now replaced it.
