- INTRODUCTION
- CRYSTALLINE SOLID STRUCTURE MADE OF
- SILICON
- ALUMINIUM
- OXYGEN
- SILICON
- Form framework with cavities
and channel inside where cation
and water may reside
- Refer as molecular sieves
- Occur naturally as minerals
- CRYSTALLINE SOLID STRUCTURE MADE OF
- USES
- 1) SHAPE
- Selective heterogeneous catalyst

- Clinoptilolite-soil
treatment which
provide potassium
- Clinoptilolite-soil
treatment which
provide potassium
- 7) PETROCHEMICAL INDUSTRY

and hydro-cracking
- Catalyst
- 1) SHAPE
- 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
- mineral
- Exclude from comercial
application because of its
impurity
- Natural zeolite form when volacanic
rocks and ash layer react with
alkaline groundwater
