Zeolite Converter

• Zeolite
• Naturally occurring mineral.
• It is Aluminosilicate having micro porosity
  of the order of 2-3 nm.
• Loosely bounded metal ions in structure is
  available for other metal exchange.

Fig The shape of para-xylene means that it can
diffuse freely in the channels of silicalite

• Highly porous and exhibit
• high surface area.
• Used in purification of gases.
• 3. Activated Charcoal
• Surface Area.
• Pretreatment.
