Multi Department Booth Project Title Exhaust Purifiers Present

Multi Department Booth Project Title : Exhaust Purifiers

Present scenario of Pollution Ø Pollution limit is being crossed drastically. Ø Which calls for need of controlling it.

Existing Solution on Pollution Platinum Catalytic Converters Limitations of Converter Fig: Platinum Catalytic converter Substitutes for such converters

The Survey :

Zeolite Converter 1. Zeolite: Naturally occurring mineral. It is Aluminosilicate having micro porosity of the order of 2 -3 nm. Fig: The shape of para-xylene means that it can diffuse freely in the channels of silicalite Loosely bounded metal ions in structure is available for other metal exchange.

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