OCCURANCE AND USES OF ZEOLITES
- INTRODUCTION
- CRYSTALLINE SOLID STRUCTURE MADE OF
- SILICON
- ALUMINIUM
- OXYGEN
- Form framework with cavities
and channel inside where cation
and water may reside
- Refer as molecular sieves
- Occur naturally as minerals
- USES
- 1) SHAPE
- Selective heterogeneous catalyst
- 2) ION EXCHANGE
- Water softner in washing detergent
- 3) ABSORPTION OF MOLECULES
- Selective gas seperation
- Gas chromatography
- Industrial process
- 4) SOLID ACID
- Cracking selectivity hydrocarbon for
fuel
- Petrochemical intermidiate
- 5)COMMERCIAL AND DOMESTIC
- WATER PURIFICATION
- SOFTENING
- 6) AGRICULTURE
- Clinoptilolite-soil
treatment which
provide potassium
- 7) PETROCHEMICAL INDUSTRY
- Catalyst
- Fluid caytalytic cracking
and hydro-cracking
- OCCURANCE
- Natural zeolite form when volacanic
rocks and ash layer react with
alkaline groundwater
- It crystallize in post-depositional
environment over period time in
shallow marine basins
- rarely pure and contiminate to :
- mineral
- metals
- quartz
- Exclude from comercial
application because of its
impurity
