Done by: ABJ_Copper8, Ali Bin Jassim Secondary Independent School for Boys Environmental Catalysis Module: Students examines different types of catalytic systems, including heterogeneous and homogeneous catalysis. Depending on the knowledge they gained during activities, the students are then asked to design their projects. Our Project: Put a plastic bag in your tank: The plastic waste can be heated to between 400 and 500 Celsius over a kaolin catalyst. This causes the plastic's long chain polymer chains to break apart in a process known as thermo-catalytic degradation. This makes the liquid fuel very similar chemically to conventional petrochemical fuels.

Pollutant
 Design Project:Th Put a plastic bag in your tank e use
of fungi to purify the environment

3. INTRODUCTION..
 Motivation is the use of a substance called catalyst able to
«increase the speed of chemical interaction by reducing /
activation energy of interaction that occurs without the
permanent chemical change».
 Also called a catalyst and catalyst Assistant factor, which is of
importance in chemistry and biology. And knows that he is
able to accelerate the rate of change of interaction without
being consumed, or by a chemical change occurs.
 The enzymes are active natural catalysts in biochemical
reactions.

4. INTRODUCTION..
 Environmental catalysts is using catalysts to
clean environment. They play an essential role in
the industry and in pollution prevention.

AS A CATALYST
Aim: To know what is the catalytic effect of the
decomposition of hydrogen peroxide(H2O2)?

7. ACTIVITY:2 SEARCHING FOR CATALYSTS
This figure shows that the catalyst works to activate the chemical reaction,
instead of crossing the interaction Tel higher energy (Black, from left to right) is
expressed in the presence of a catalyst Tel smaller energy (red).

16. PROJECT: PUT A PLASTIC BAG IN YOUR TANK
 Many types and forms of plastic pollution exist in
our environment.
 Plastic pollution can adversely affect lands,
waterways and oceans. Plastic reduction efforts
have occurred in some areas in attempts to
reduce plastic consumption and promote plastic
recycling .
 The prominence of plastic pollution is correlated
with plastics being inexpensive and durable,
which lends to high levels of plastics used by
humans

17. THE CATALYST KAOLIN
 The catalyst, Kaolin is a clay mineral --
containing aluminum and silicon.
 It acts as a catalyst by providing a large
reactive surface on which the polymer
molecules can sit and so be exposed to
high temperature inside the batch reactor

18. MATERIALS AND METHODS
 We need to heat the plastic waste to between 400 and
500 Celsius over a kaolin catalyst.
 This causes the plastic's long chain polymer chains
to break apart in a process known as thermo-catalytic
degradation.
 This makes the liquid fuel very similar chemically to
conventional petrochemical fuels.
 This requires catalyst 1 kg of kaolin for every 2 kg of
plastic.

19. RESULTS AND CONCLUSION:
 To develop a commercially viable technology for
efficiently rendering LDPE into a liquid fuel . If
applied on a large enough scale, reduce
pressures on landfill as well as increase supply of
petrochemicals for fuel
 For every kilogram of waste plastic they could
produce 700 grams of liquid fuel.
